Just curious if anyone in here races there chicken im not talking abou drag racing either. Last year i dirt tracked a 91 mn12 tbird with moderate sucess and this year im building a foxbody tbird to take on the chevys.
No way.An occassional drag,sure,but nothing that would involve rubbing panels with another car.This is a special car,not a dirt track car at all.Now if it's an MN12 car,sure,race 'em til you kill 'em.Not the Fox body.
i've thought about it, in hobby stock. i watched a guy run i think a 86 with the plastic nose of an 87-88.. he spent the whole time under the hood so as you can assume he didnt run well. but i was suprised to see a fox ford in hobby (with prolly a 351 swap)
Dirt's for plantin'. :flame: Asphalt and concrete are for racing.
When finished, the one on the left will be seeing lots of track time. I've got some old pics (from before the build) of it cooking rubber, including some from in Vinnie's neighborhood.
dirts for fun asphalt is for being serious. competition is better on dirt, more difficult on asphalt, apples n oranges.
its hard to run a tbird as a hobby stock ive tried alot of tracks outlaww them an the mn12 b/c the car of choice , metric monty carlo, cant compete with them when there running right. Im racing my foxbody this year and hopefully get a few more wins under my belt. fox body cars arent that rare and the suspension makes them great race cars. As far as dirt vs concrete its like comparing drag racers vs real racers. dirt more about the driver while pavement more about the car, oval more about the driver while drag more about the car. If you crazy like me you run figure 8 and put ur car on the line at any lap she could be totaled but still run like hell and shoot the gap.
http://www.myspace.com/midgetracing28 go to this link and under pictures and fig 8 cars theres some pics of the old 91 b4 the first race and after the season with some body damage lol. B4 anyone says anytihng the blue house in the back ground isnt mine im on the other side of the street lol.
Hey, go ahead and dirt track race it... Its your car...
Welcome to the site, any questions go ahead and ask. Dont take them too serious. Just try to do it with a rusted out car...
i gotta deal with a guy that owns a junkyard he holds these cars for me and waits to take them to the crusher until after i get use outta them. so its a win win really the cars get some final glory moments and i get cheap chassis's and no i hardly ever take a rust free car on the track when i have to cut most of car up anyway to get them down light enough.
I've actually got a question for everyone preferably the v8 guys. Ive got some fairly open engine rules compared to most other dirt series.
Stock block and heads (no porting) max 360 ci
aftermarket intake ok
After market carb ok (no efi)
no electric fuel pumps
headers ok
Stock style ingitions only hei legal ( ive already made up my mind and found descently priced hei distributors for ford v8s)
aftermarket pulleys ok
pump gas only 93 octane max
engine must pull 15psi of vacuum at 1000rpm.
So what would be the better engine to start with a 302 or 351w?
Find a Explorer 5.0 and use that, they have the better flowing GT40 heads... With a good intake and 600-650cfm carb it would be a tough combo...
Those heads on a 351 would be even better but you will have the extra weight... BTW I believe the 351 is approx the same weight a s SB Chevy... The 5.0 is 60-70 lbs lighter... A killer combo would be a 5.0 stroked to 331 or 347...
I don't even drive mine on dirt roads.
the 5.0 is about 100lbs lighter than a race ready chevy 350. i like the engine they make descent power through the upper rpms. Ive heard of people taking the heads off of 289s and putting them on 351s and 302s but im not sure what all work would have to be done to this. A friend of mine that races bmod raced a fox tbird 2 years ago as a hobby stock won all but 3 races in the car and he had a stock 351w bottom end with 289 heads. wicked fast car every body hated him b/c he was beating them with a chicken.
Except for the smaller combustion chambers 289 heads ain't nothing special(on a 351 prob at least 10.5 CR)... they have minuscule exhaust ports as does most stock 302/351 heads... The GT40 and '69-'71 351 heads are actually very similar... With the GT40 being the better of the two...
is there any place to get reman gt40 heads? or does anyone on here have a set up for sale lol. Ill be using a crane z cam long tube headers and a aftermarket intake from speedway with 750 holley double pumper to get as much outta the stock 302 as i can.
explorer 5.0 motors have gt40 heads
what years?
newer efi ones.. can't give you exact numbers right now...
95 - 97.5 gt40
97.5 - 01 gt40p
will they work with standard ford intakes ? are they a direct bolt on or would i need to get them machined ?
I know of no SB Fords other than the Boss and Tunnel Port(extremely rare) 302s that require special intakes... Maybe some exotict after market stuff, but not the factory pieces...
i was just askin b/c i saw a gt40 take in a jegs catalog and wondered if that was the deal.
I'd be more than happy to help in anyway I can.
I've got a carbed V8. The big question I have for you is what tranny are you gonna run???
I used E7 heads which were from a High Output motor. 130 bucks and they did a grind job on them.
If you're looking at the gt40's and P's then expect to spend 300 bucks just for the heads. Plus the money for the grind job.
Also the Header options for the GT40's & P's are limited because of the spark plug angle. If you have specific questions PM Cougar SE. He'll help you out alot.
ive got a c4 and aod trans which are both stock cofiguration b/c of the rules. Theres a 9 inch ford rearend which will either be getting 3:50 or 3:70 gears with minispool.ive got a set of e5 truck heads but ive heard some people say there descent and others say there better off as boat anchors.
(http://i25.photobucket.com/albums/c73/gmby23/24.gif)
P's YES, special header preferred, BUT I've heard of using the short bodied Accel plugs and running std headers...
Regular GT40s use the std plug location... AFIK any header fit's these...
E5 truck heads are basically the same as the E7TE used on the '87-up HO's... OK but GT40s kick their ass...
Claude (CougarSE) has a set of GT40's and GT40p's. IMHO he's the person to ask questions about them.
If the e5s are descent heads i might throw the 351w i have back together, i tore it down in hope to build a 393 stroker, unless i can swap these back onto a 302. id prefer the 302 just because of the weight and the well... i never had a problem sticking with the last class i was in using a bone stock 302 non ho against 350s and many 355 sbc's no one beleived me it was a 80,000 mile 302 out of a 85 crown vic. I know a few modified and late model guys that love there ford engines but there very divided on which is the better platform 351w or 302.
just updating i got the 5.0 and aod in the 84 bird along with a 5 lug conversion up front and 95 mustang 8.8 rearend with ford racing, springs, global west urethane bushings all the way around camber plates, nylon brake line kit, 16 gallon fuel cell, monroe shocks and struts sensitrac (rules require a stock style shock), 14 point roll cage, and trimmed away about as much sheetmetal as i could possibly get a torch too lol. i will post some pics as soon as i get her painted and lettered
have fun and don't wreck the car up to bad if you can but if all else fails go back to tearing up the MN12s.
I think you'd be better off with a 650DP carb, the 750 is too big. But then again, you may not need the throttle response and the 750 is slightly easier to tune in it's stock form.
Do you have a carb rule or a carb claimer rule?
Oh, and stick with the 302. Handling is much more important than horsepower.
o i changed the classes and this one has to use a stock style carb so ill either be using my 500cfm 2 barrel or if i can find a cast iron 4 barrel intake i could use the old ford 4 barrel i have not sure on the cfm just know it has center hung floats so it would be alot better in that respect. im still looking for a larger hydraulic cam that will still have my engine pulling 15psi of vacuum which is becoming a real pain to find any one have any suggestions let me know.
The Ford 4100 four bbl carbs are either 470 cfm(small block) or 595 cfm(big blocks)... The 595 unit will have 1.21 cast into the driver side of the float bowl... Unfortunately the ed things are getting scarce and pricey...
Could you run a four bbl Holley from a '84-'85 Stang??? Those have a Ford part number on the air horn... There are other Ford Holleys as well...
The 4412 500cfm carb is a good one, and can be made to make good power. I would use it over a "stock-OEM" 4bbl any day.
Email me once you know your carb rules and specs.
it has to be a factory piece and can be modified so i either have to use the motorcraft 2 barrel or factory ford 4 barrel so long as it came from the factory its fair game after that for being hogged out. beleive me i would much rather have the 4412 be legal. and the 4 barrel i have is off an 84 stang if that helps any wether its stock or not idk i havent had my carb guy touch it yet b/c ive found it near impossible to find a 4 barrel cast iron intake for a 302
i have an intake its a D1 piece off of a boat motor. has the standard holley bolt pattern. pretty rusty though but it is a factory piece and it is cast iron
The only 302s I know of to come with a Cast Iron 4bbl intake were the '68s... The 289s did get a 4bbl from '63-67... The '65 & '66 used to be very common...
Sold a C5 from a '65 289 a few years back for $85... I'm sure I could find you one for roughly the same, but shipping would be killer... Main prob is they flow rather poorly... If you were going to use the 2bbl Holley, a hogged out 2bbl manifold would probably be just as good...
BTW the large Autolite/Motorcraft 2bbls Had a flow of 350CFM, I believe they were cast 1.34 on the side of the housing... Those come cast as small as .98 that were on the early 221s...
ill prolly just stick with my trusty 2 barrel she works good it just acts up when the filter gets a lil dusty.

finally someone else who gives the birds a good workout
can you not use one of the factory 84-95 mustang aluminum factory intakes?
nope cast iron only i found a 4 barrel intake for a 289 that ill be switching to when i change the cam.
well the car is running and driving with 2 weeks til race season i still need to prime and paint it but other than that she ready to rock. took it out for a test run in a open feild to get the feel of her and she is a bit of a handfull compared to the last car i need to lighten up the front end without weakening it any ideas b/c im still nose heavy. as a last resort i might have to get some lead to put inthe trunk to get my percentages right.
