Ishould have been more percice. I want to upgrade my engine this spring .351w .30over stock rods and pistons ,Edelbrock performer with a 750 Holley,Roush200 heads Comp xe4x4 226-234 with 512 lift and 111 ls,Crane gold roller rockers,Duraspark ign with MSD ,Headman headers long tube .I would like some suggestions on an upgrade for more torque or horse power .

come on, Somebody has got to have some idea's

My suggestion are...
First, ditch the performer and step up to a stealth or an AIRGAP. Then go to an 1 3/4 header.... those hedamns you have are more than likely 1 5/8"... correct? I went from hedman long tube 1 5/8 to Accufab 1 3/4" on my 302 and it made a huge flow difference.
Between your headers and intake, you are losing a lot.

I agree that the performer is likely the biggest bottleneck in that combo.It says you have a performer rpm in your sig???

I do have a rpm on the shelf ,I used it for a short time and it didn't seem to do much for it. Never got it to the track to see if there was a difference.Been thinking about advancing my cam timing,to get more torque to get this sled rolling.

Same place I got mine:

Put the RPM back on when you add the 750 Holley carb and the heads. There will be a difference then, especially at higher RPM's.
