300-330 rwhp. The heads, cam, intake, throttle body and shorty headers are killing it.
+1, the entire top end of that motor is choking it out terribly, 302 parts on a 351 make 302 power out of a 351
I had damn near the exact combo but in reverse. haha. I had trick flow heads and cam and eddy intake. That combo made 360/395 so yea i guess those 302 parts deffinatly choked me off.
Personally i think thats where alot of people mess up. they slap on the biggest heads and intake they can (even on 302's) and they dont do research first. There is a fine line between good port volume and velocity. You should try to find a good median between the two, but stay a little more on the velocity side.
edit: oh yea my compression was around 9:1 i believe.
and he could certainly benefit from a custom camshaft and a better flowing top end with the extra cubic inches he has to work with. Longtubes and a larger throttle body would be nice too, don't you think?
Did your combo put down those numbers on a Mustang Dyno or Dynojet? I'm not doubting you at all, FYI, just curious.

Trick Flow heads are FAR better than Edelbrock performers first of all, and you had a custom cam you say. Are you trying to say those numbers are good for a 351?? A 331 will make those numbers with a bogus combo without breaking a sweat. A 351 with a proper top end will make over 400rwhp piece of cake. This "velocity" bs doesn't work the way you think it does. Choosing small parts only gets you small numbers.
There's never enough money to do it right but there's always enough money to do it twice.

I don’t think anyone could come up with a better true statement then that, even if they tried. That is the problem a lot of times…we have all done it.

show me anyone on here who is making those numbers so easy with an efi motor. i can think of maybe two people. and of those two people they had pro built motors.
