What manifold options are people going with for drag racing? I have a Fast 102mm intake on a forged LSX 427cid with Mast 305cc heads. We are seeing MAP drop at higher RPM with the current Fast intake.

Is anyone running twin throttle bodies on sheetmetal intakes? I seem to remember seeing someone that had such a setup

 

Check John Marcella.

Marcella is also top notch. http://marcellamanifolds.net/images/Images.html

Beck's also.

Beck built nice intakes, but he doesn't do it anymore. TRE took that over from him and they build a pile of ****.

 

Didnt know that. Pretty damn shame cuz Beck did a badass job with their intakes.
