Anybody here run a blower on a 470RB? I was going the tunnel ram route on some 240 Trickflows but now I am thinking... hmmm... I am at 10.5:1 compression which would be perfect for methanol. The issue I have is the stock block! Not sure I could detune it enough to keep from splitting it. NOT BUILDING A RACECAR although it does have RMVB 727 and 4000 8 inch converter, Dana 60 with 4.10 gears and CalTracs. Just a radical street car. Any setups you would care to share?
