I find myself pondering about an evac kit for my truck, I have a rather high flowing exhaust an high reving engine its a 3'' in x-pipe system with no tail pipes just dump before rear axle with spintch mufflers, has anybody done a evac kit for a street strip vehicle? it helped alot on my bracket vehicle now im wondering if it will help my high rpm SB

My buddy put an evac kit on his car, a 1964 Ford Thunderbolt clone. High revving small block ford. The evac kit worked so well, it sucked out oil too and his car smoked like crazy... so it took it off never to be used again....

I ran one on the street in a roller cammed, 12.5-1, dual 660's, 401 in a cj-5 Jeep, which shot flames out the side about 3 feet. Only vehicle I ever had that could lift the front end.

The evac was fine. You've got baffled valve covers and try not to put it right over top of a pushrod if possible.
