Good riddance to the smog pump (among other things) September 02, 2008, 01:47:53 AM I figured labor day weekend would be a good time to get around to sping the smog pump. It hasn't been hooked up for quite some time and my cats are non existent, so might as well get it off the pulley system, right? I give most of the credit to jcassity for all the information taken from what I like to call the "master thread". The next step will be deleting the EGR and with any luck it will run as it should. The simple mods I've made so far have done a fair amount to wake up the old girl. Mods so far: V8 throttle body swap - aftermarket electric fan w/ thermostatic relay - cat converters removed - engine rebuilt and bored .030 over - emission system removed (smog pump and all)- a/c removed. Average 0-60 time is 11.5-12 seconds and fuel economy has been 17 city/ 28 highway. 3.8 V6 AOD w/ 3.27 gears. Quote Selected

I would estimate a whopping 110-120 at the wheels. It's no speed demon, but it feels good not having the motor choked out by unnecessary junk.Quote from: vinnietbird;234555When do you plan to do the 3.8 delete? The only engine swap this car will ever see might be an upgrade to 4.2 internals. I'm all about the unpopular engine :D My intentions here are not necessarily to add power, but to get the engine back to basics. If it doesn't need something to run properly, it's coming off.

Good riddance to the smog pump (among other things) Reply #6 – September 03, 2008, 12:16:11 AM Wow, I wasnt aware that there were so many v6 modders out there.That engine setup in your sig looks awesome blackcougar71, any other pics or info that setup anywhere that i missed?I'm gonna be running my stock v6 for awhile as well, so im looking for any and all ways to wake her up, heh. :hick:Coolcats and the books say they come from the factory with about 112-120HP and 250@1600 torque (same as a 5.0?!).Has always seemed like that HP number is bogged down, like you should easily be able to release some horses.... dunno.

The v8 offers 45 better than the 6. Not too shabby considering the average cars of today are lucky to break the 200 mark. Due to advances in variable timing and all that junk, we are definitely nursing dinosaurs. On the plus side, we get roughly the same mileage though! Quote Selected

The v8 offers 45 better than the 6V8 torque increased with SEFI -- it was listed as 270 for 86-87 and 265 for 88 (somehow the faux dual exhaust gaioned 5 hp at the cost of 5 tq) Quote Selected
Good riddance to the smog pump (among other things) Reply #9 – September 03, 2008, 11:25:38 AM my attempt at the 4.2 stroker swap was halted for parts reasons but............Recently tom made the comment that 87 and down engines without internal balancers should work just as long as you bring in the flywheel associated to the 4.2crank. I never checked the tooth count but they should be the same.Having said that, the pully on the 4.2 will need to be included with no harmonic.This will change pully alignment for the rest of the bolt ons like p/s , alt ect.Good luck,, it was always my thought that the 4.2 stroker will only work in the 88 v6 engines but I must be wrong.On that smog pump,,,,,,,,, did you run into a blue bolt? THe blue bolt was my smog pivit bolt and passed through the water jacket. not sure if yours did or not.The major thing about the 4.2 rods are that the rod caps are broken off. this means that they are toast if there is spun bearing and its likely they cant even be broached. The crank is steel and the rods are floating, vs your stock setup which has a cast crank, floating piston and repairable rod journals.Someone needs to figure out a way to gut the intake more,,, I have cut the intake in every direction imaginable with a metal bandsaw just to find a weakness and there isnt anything stopping you from going crazy with grinding tools. I would remove the v8 tb , split in in half and hone out the entire hole on each side to match the butterflies. there is a choke point even on the v8 TB. Do not hone the half with the butterflies,,,,,,,I learned that butterflies are not round!! the hard way.The block needs to be true for each cyl hole now more than ever. If you use a stock compression ring, measure the end gap of just the cmpression ring at the top, middle and bottom. Use a piston to scoot the ring down to the next spot to be measured. This task is important to take perfect notes on so your block can be cut with perfect holes and respective or stock pistons used. The use of the 4.2 crank/rods increases your "rod angle" and will oblong your cyl wall out in the middle area sooner than your stock crank/rods will.Like i said,, your virgin topic for now is the open up the stock intake more on each runner. to date, this has not been done by anywone because it really has not been a popular engine to start with.

THe blue bolt was my smog pivit bolt and passed through the water jacket. not sure if yours did or not.Yup, ran into the blue bolt as foretold in the how-to thread, and reinstalled it after yanking the pump out. It went incredibly smoothly and i only had to use a pry bar to knock out the pump after the bolts were taken off. I also forgot that I plan to pick up a pair of stock headers from a newer model tbird/mustang. Does anyone know if the stock y pipe can be reused with the headers in place of the stock manifolds? That's pretty much the only thing holding me back at this point - I don't have the resources to make a custom pipe and nowhere around here will install an exhaust system without also installing brand new cat converters.

Good riddance to the smog pump (among other things) Reply #13 – September 05, 2008, 02:53:17 AM not sure on the header thing,, if they are free and you see it isnt gonna work your not out anything. I had to mate some shorties my stock y pipe a while back and the only thing i had to do to the v6 y pipe was get the end flaired more to mate up to the shortie. I scooted the fitting up to the end and then reflaired to the desired diameter , then i had to grind a little to make the header bolts clear.this was all on the white coug. Quote Selected
