Possible HP?

[mustang283]

1991 mustang gt 5.0 block

331 stroker kit
victor jr aluminum heads
trick flow R series intake
X303 cam
75mm eddelbrock throttlebody/matching mass air meter
30 OR 39lb injectors
WITH A TUNE


What would you guys guess possible HP area would be with this build?
(my buddy's 331 with gt40 heads and gt40 intake, TFS1 cam, 30lb inj, made 294rwhp on a dyno, not a dynojet)

just watched a similar build make like 320/322 at my local mustang dyno.

what compression? what size exhaust?, this along with a different cam choice could mean the difference in 320 rwhp and 370 rwhp.

Id scratch the X cam idea, doesnt make sense on that setup. But Compression ratio, pump or race gas all play a factor. But 350 rwhp is my guess!

348.9 / 319.2

You definitely need more cam, but i'm gonna say in the neighborhood of 350hp. My buddy's 347 with Victor Jr heads, an Ed Curtis cam (240 duration, 580/630 lift), 11.3:1 CR, Systemax intake and all the typical supporting parts made 385/399.

I'm going to say 330hp and 333 torque.
