Edelbroock RPM head on a 393

[Redge]

I already have those Edelbroock RPM head with 2.02/1.60 valves on my 302 and those head have been ported. My beat run with my current 302 is 12.626@113.276 MPH in a 2950 Lbs fox mustang. I just bought a 351 short block and i plan to stroke it to a 393.

Here the plan :

Buy a Scat 9000 3.850 cast crank
Buy a set of forged 5140 I-beam rods ( press pin )
Keep my current .040 Keigh Black 115 piston
Keep my Edelbroock RPM head
Keep my Edelbroock RPM camshaft
buy an Edelbrock victor jr. intake or an AIR GAp
keep my holley 650DP

Here is the flow number of the ported RPM head

RPM INTAKE EXHAUST
100 56.4 49.5
200 117 103
300 171 144.6
400 218 166.9
500 237 174

Here is the Edelbrock RPM cam spec :

Duration Advertise 290/300
Duration @.050 224/234
Lift at valve .496/.520
Lobe Seperation 112
Intake centerline 107

I use my car for street and strip. I really want to keep my RPM head for budget reason but i can change the camshaft and the carb. I dont want to rev it pass 6000 RPM. In dyno2003 i got 447HP@6000 rpm and 449 torque @4500 rpm.

Can i really have that kind of power ?
Should i change the Edelbrook cam ?
Witch intake will fit the best with my RPM head, the Victor jr. or the Air Gap.

Tanks to everyone

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 ?
