How fast will it be?

[tylerrocks]

Sorry if you guys are tired of seeing these kind of threads but here goes.

Stock roller 302 short block with forged pistons.
Untouched GT-40p heads with 1.7 roller rockers
F303 cam
Edelbrock RPM (non-airgap) intake
Speed Demon 650 mech. secondaries

Driven with a T5 and 4.11 gears

How much RWHP can I expect?
This will be in a 2600 lbs car, what can I expect in the quarter mile?

mid to high 13's

I had performer RPM heads performer rpm air gap intake. With F cam, 1.6 rockers 650dp and 3.55's in a stick car and went 12.6@106 with 7 cylinders. You should go high high 11's

3450lbs with me inside.

I thought 11's sounded low too, but I think high 13's sound high. I was kinda thinkin 12's, just wanted some more opinions.

Also, can anyone geustimate RWHP? Is 275 plausible?

Hmmmm sounds far fetched to me

what's the suspension? dr's or slicks?

 

[tylerrocks]

Street trim. 245's. This car is actualy 64 mustang, I figured the 5.0 forums would yield better info than the classics. That being said, The suspension consists of 5 leaf springs and KYB shocks. I'm not a hardcore racer, just tryin to get a feel for how fast it will go.

I would say somewhere in the 12's because how light the car is... but i can't say for sure.

Untouched GT-40Ps and that combo, my guess is 250-280...

In a 2600 lb car (thats LIGHT) Id be willing to bet it could go 11s with traction. My car made 265 and in a 3200 lb car went 12.5! Similar or more power in a car 600 lbs lighter, should definately be much faster!
