I need some intake manifold recomendations for my 360 build. It is a mild bracket car (1/8 mile). No street time at all. 3000#, 2500 RPM convertor. 9.25:1 compression 360 LA motor, Lightly massaged iron heads with 2.02 intake valves, 5.12 gear, 28" DOT tires, Small tube shorty headers, Comp 280H cam (.480 lift, 230degrees at .050) and valvetrain.
I know that there is a lot of 360 expertise and experience out there and I'd sure like to tap into it.

M1 single plane. More torque than Eddy since your not going to rev 6500+/

Air gab real hard to beat overall

LD340 will work real well too.

Edelbrock Rpm or LD340 would be good. More converter would also help.

My car picked up a tenth in the quarter when I went from an M1 single plane to a Performer RPM Air Gap. My compression is about 9.7.

Did you make any other changes or was the .10 all because of changing out the M1 on your 360?

Is an LD340 the same as a D4B ?

I'm not a racer but I've been using the Weiand Stealth dual plane on my 360 for about the last 8 years. It did good on the first build, and it seems even better on my most recent build (six months ago). Engine is now a mild Eddy headed 360 with about 400hp. The Stealth is priced really well especially for the performance that it yields too

air gap or ld 340 had both they are about as good as it get's till yuo get into the hard core race stuff!
