OLDER EDELBROCK PERFORMER INTAKE POTENTIAL ON A 340

Hi Folks

Just wondering how this manifold stacks up against the OEM 1971 cast intake and the LD 340 intake. I would be running a factory TQ ON A 1971 340 with about 9.3 : 1 SCR. Cam is a Comp XE 262 with a 727 (2500 stall), and sure grip 3.23's in a 1971 Demon. I would gasket match the intake ports, but that would be it for mods. I like the LD, but I don't want to modify it for the TQ. What say Ye? Thanks FABO

If you don't already have an LD340, you could look for one of the later issues of the manifold- their carburetor flange is already set up for a TQ with extra material around the carb flange's secondary area, unlike the earlier manifolds. All you have to do is open up the secondary area a bit.

Between the Performer and the factory manifold, about the only advantage to the Performer is less weight. I doubt you'd notice much, if any, difference performance-wise.
