440RB INDY DUEL PLANE OR RPM INTAKE HELP

IQ52 said

There are no benefits to single plane for your service requirements even with that size of engine unless you wish to reduce the amount of torque you have at lower rpms. I've done dyno tests on this size engine with the RPM manifold and the Victor single plane. With the gasket matched RPM manifold vs the gasket matched Victor you will gain as much as 40 LB-FT at lower rpm's and lose maybe 15 HP at 6,000 rpm.

Hi Thanks for your input.
I build a few engines and dyno every say 12 weeks i am on a dyno, but im the only person around where i am that does Chrysler big blocks.
I did a low deck 2 months agao with an rpm intake and heads,470 cubes and a 236/242 hyd roller that the lifters tapped out at 5800rpm and made 580hp/600 lb/ft @10.7.1 on 98 octane BP fuel.
This sat i am dyno tuning the 493 with 248/254 solid roller,indy ez max wedge, 11.1.1 comp and indy single plane with 950 carb that im shooting for 700hp.
I was considering the holley stealth on the stroker with the trickflows and small solid, if i experimented with this i may want to try asingle plane.
2 questions
Is the mopar M1 as low as the edelbrock RPM to fit under bonnet so i could try it with efi.
And second question does this efi stuff really work?
I had a indy duel plane that fit uner the bonnet before has anybody got the heights for these 3 intakes??
Thanks
