The injectors should be orange for the HO 19lb.
Tan are the SO 14lb that your car already has.

Seen lotsa HO inj that  looked tan...

The whitish gray are the 14s used in the SO...

E6 headed 200Hp 5.0 HOs used 19lb inj, same as the 225Hp E7 headed versions... Generally the '86 HO used a std intake(and unique 58mm throttle body), look for a '87-up...

For the record, i did what I posted, the car averaged 28 miles per gallon from Dubuque to St. Paul Minnesota and Back with the 302, E303 camshaft, 76mm mass air meter, A9P computer, 30 lb/hr injectors, 190 lph Holley fuel pump, Holley Systemax II intake, Keith Craft CNC stage III ported Windsor Junior heads and a stock 89 GT block that does not have EGR or Thermactors.  This was with a .80 overdrive and 3.73 final gears.  The car scales at 3675 pounds with nine gallons of fuel and has run a best of 13.468 in the quarter mile @ 103 mph.  The speed density from the 88 Mustang GT that we tried a the beginning did not like the E cam at all so we converted to mass air and it ran perfect.
Blueprinted 306, Thumper ported Canfield 195's, TLSR Camshaft, custom motor mounts, Parker funnelweb, Pro Systems Carburetor, Tremec 3550 II, 4.30 gears, Moser Axles, Team Z custom suspension with upper relocation brackets and anti roll bar.  At the track I run M/T 26/10's on Weld Star rims.

No doubt, but IF he's going to run the flat top pistons there won't be clearance for a "E" cam... So speed densety will work fine...

Now if you want a good combo, get a set of Trick Flow heads and run 'em on flat tops like I do(with mas air of course)... Before my shiznit wore out, I've gone 13.11 @ 105.3... IF I'd have put more converter in it(only have a 2600) high 12's would have been easy...

HEY !!! Scared is such an unfriendly term,I prefer..........well,O.K.,scared (at the time,before I found the real problem)..I thought I had problems related to the E cam then found out I needed spacers under my roller rockers because with the milled heads the lifters were compressed to much.The E cam IS going back in.I still have to order gaskets to do the job.Probably in the nesxt few weeks if the weather holds out and I have a dry/warm place to work.I just ordered a set of the quality valve guide seals (not the umbrella type).As a matter of fact,I had enough PTV clearance with the E cam,and the heads were slightly milled.Crazy,but I swear it's true.I'm selling my extra parts to finance this,and gather parts for my a/c pieces and 5 speed swap.One piece at a time.

When I installed the E303,I had ported E-6 heads with a 3 angle valve job on (not that the valve job made a difference).Now,E-7 heads.We did clay,and there was room enough for the cam to work fine.As a matter of fact,I drove it for a week until I figured out that it was the rockers,not the cam.I have faith that it'll be fine.I'll have a thread with all of the info,pics,and results.

Kitz,you didn't set me off.Without your constant harassment.....I mean "encouragement",I would've sold the cam and been done with it.

Sorry Vin :hick:

I was asking Kitz as I already knew your setup ;)

Still it is good to post it up for reference though.....

So what say you Kitz?  What heads with a 512 lift cam and which cam for that matter?

It's E7's with the E cam and 1.7 rockers.I'm pretty sure it wont work but since I have my spare motor apart I can play with it.

I plan to buy a new cam and have been doing some looking. Lots of numbers out there. What are the specs on the stock Mustang cam?
Any benefit in paying for a Ford cam?
