Hey yall, looking for opinions and insight. I'm building up a 340 for a tube chassis 87 Charger. There's a thread on here on this basket case that I'm slowly making progress on.
It'll be around 13:1, iron heads, running on E85.
Prior build had the simple crankcase evac to the collectors from the valve covers. The old check valves were shot, so I either need to order a new evac kit, or a vacuum pump. Is there a major advantage to running a vac pump, or is the old school exhaust evac fine for my old school build? Thanks for the advise.
