build me an engine!

BLOCKER · 09-15-2001, 09:03 PM

Assume you are starting off with a stock 88 5.0 HO (non mass air)
(okay mine is going to need a rebuild soon so I figured what the heck!)

I have decided on the following up grades:
Cobra upper/lower
gt40 heads

what cam should I use?
what rebuild kit?
what compression ratio? (9:1 or higher)
what else should I do?

please keep in mind I want to keep the car a 5.0 (not stroke it) and I want something that is very streetable, not too clunky

thankx

well if your gonna stay NA the Cobra intake is perfect, I'd consider either AFR165's or TFS heads instead of GT40, as for the cam, F303 maybe? get some 1.6 roller rockers for sure and make, i wouldnt go any higher than 9.5:1
if you are gonna rebuild it then you will need to bore it .030 over, this will take your displacement to 306ci, still a 5.0 though, depending on how radical of a cam you go with, you may have to convert to mass air, its not hard to do, i did it recently just to get rid of a small surge in my idle, i only spent a total of $150 to do mine with a 75mm Pro-m meter that i got used for cheap
good luck with it

what is the B303 cam like, I was reading and the GT 40 engines from ford all have that cam,

also would I be able to use 24# injectors with a s.d. engine or would I have to convert to mass air? recalibrate my computer ect...

thanks

Explorer intake
B303 camshaft
GT-40p Heads, lightly exhuast ported
Motorsport GT40p headers
adjustable fuel pressure regulator
19lb injectors

320hp, capable of 12's easy with traction.

The B303 is a higher rpm cam than the E303 with more duration 224*@.500 vs 220*@.500 for the E303.

The B303 seems to respond well to 1.7:1 roller rockers, but I don't think unless you do a heavy port to the GT40p's you'd need that.

Keep the combo matched, and the wild cams and heads out of the equation and your speed density system will do just fine with you adjusting the fuel pressure. Until you hit 350hp, you will not need 24lb injectors. If you get there, again, just adjust the fuel pressure and SD will run fine with them.

how does this sound

cobra upper and lower intake
GT 40 heads (ported to match intake and exaust)
1.6 roler rockers
E303 cam
19# injectors,

with this combo should I still be able to run SD?
what hp to exepect?
