Intake/carb selection
 
OK here is my set-up. Remember this is a street/strip car(mostly street).

.030 over 350 sbc, flat top pistons (4 eyebrow), 461 heads, MSD ignition, cam I am not sure of exact size but it is approx. .540 lift with 308 dur.
I am currently running a weiand tunnel ram w/ 2 450 holley's. 4 speed trans., 4.56 gear, with 30/14.5/15 M&H cheater slicks.

My problem is that on the track the car launches hard then noses over due to lack of low end power. Slowly powers back up then runs real strong in the upper RPM's.

I am thinking of going with a single carb but not sure of which intake/carb would be best for my application. Any suggestions??

Get rid of the tunnel ram. If you are conservative on the RPM's, get a dual plane intake and a double pumper. For a street/strip 4 speed car, this will give you back the lower end .

I forgot I shift at 6800 now and cross the 1/4 at 6500 in 4th gear.

I was thinking of running a 750 holley but not sure what intake to choose.

I would go with the Edelbrock RPM Air Gap intake, the reccomended range is 1500 to 6500.

what rpm
 
How many R's off the line are you leaving at. What tranny are you using, & first gear ratio?

HEY RABBIT,I agree with Dave.A 750dp will give you plenty of juice for that motor.I put the same setup on my wifes"small block and it works just fine in her TransAm.FISHMANJOE
