Edelbroock RPM head on a 393

[91whiteghost]

we ran a 90 mustang with a 351 with twisted wedge heads a comp cams 286 magnum cam shorty headers and a weiand dual plane with a 750 carb, car weighed 2800 lbs with driver 5500stall converter, 4.88 gears, 13.5 by31 Mickey Thomsons and ran 11.30 on 93 unleaded. max rpm was 7000. The Victor Jr is to big if you are only going to turn 6000 rpm , You will lose bottom end torque , although the bigger cubes will help.I would use either the Rpm air gap351 or the torker 2. The weiand stealth is also a good manifold i have found it have good bottom end as well as able to make power up to about 7000 rpm

So i'd be better with the Air Gap RPM intake if i want to get a better torque/power curve. It's right on the RPM range i wanted. The Air gap on my 302 was perfect with those head.

Do i need to change the edelbrook valve spings and convert to stud type roller rocker if i want change for a bigger cam or can i keep the pedestal mount 1.6 roller rocker i have on my 302.

I have a goal of 450Hp and 450 Ft-lbs Torque and low 11sec at track. I will need better Transmision with that kind of power .

For the compression ratio, i get 11.33 with a 9.503 deck, 60cc chamber and a .041 tick gasket.

Should i mill down the deck and get dish pistons to maximise quench? What compression ratio should id stay to run on pump gaz ?
