im am attempting to do a upgrade for a customer of mine but i am unsure of the things i need to make this work. ok heres the current layout. 86 gt T top mustang. flowmasters catted h pipe and mac shortys. stock 160 hp flat tappet cam non HO engine. what the plan is a rebuilt E7 block with ported E7 heads and a 95 cobra cam and rockers and the HO EFI intake now will the stock fuel system work or is this too extreame for a speed densedy system? or will this work at all cuz i was considering a E303 cam for this car it is a 5 speed.

the heads will be fine, intake fine, im not sure of the specs on the cobra cam...do you have them? if so post, ill tell you if its ok or not... and the e cam will be a no good...

so yea, your good, just gotta check out those cam specs 1st

dimebag

cobra cam will be fine, stock duration, but a little more lift(.479/.479 with 1.7s)(as opposed to the gt stocker with .444 with 1.6s)

thx to adder for the cam numbers, cuz u know my *** didnt look those up, lol)


this is going to be on a e7 motors bottom end right? were not talking the 86 short block with the flat top pistons right??????

yea it will be on a E7 engine but with speed pro hypers what would be the cam lift with the 1.6 rocker on a cobra cam?

schwindty

1.7 Ratio rockers increase lift by .30 if I remember correct. Pretty sure anyways... so that cam with 1.6 will be.449. If your going to be taking all that apart why not stick with the 1.7 Ratio roller rockers. They are still one of the best bangs for the buck I think....smooths out your valvetrain. As well not sure if he has the parts already or everything was free, it would be a sweet time for a nice intake!

dimebag

the cobra cam came in conjunction w. 1.7 RRs... just for some insight

mayhem motorsports

we will be sticking with the 1.7 rollers what kind of power do you guys think it might make with all these mods and a 5 speed?

dimebag

idk about power, i suck at guessing that... but i say, if he hooks... street tires=low 14, DRs=high 13 its not gonna give you much over stock... but some.

schwindty

I would say about 200 to 210ish at the wheels mabye a bit more pending on how much porting your doing on the heads.......who is doing the port work? Think about aftermarket throttle body and intake, they make a world of differencein conjenction with ported heads.

mayhem motorsports

yea i know that. pretty much the guy is trying to get his car to be a mass air car but upgrade all the other stuff later inake throttle body injectors stuff like that cam etc.etc.
