Header evac with mufflers

My buddy Jerry has the same Evac set up on his Nova 364 CI and a 400 Hit of NOS. He has fender well headers and mufflers about 4' away from the collector. Evac is in the collector. The system works xlnt. He has NO Vac Pump and running that much juice. Car runs 5.80's in the 1/8, it is no slouch.

My lil 340 before I pulled it had the same set up. It worked great. My mufflers were in the standard place and exhaust dumped at the axle.
