I have 1966 chevelle and a pro street jeep wrangler I got a few years ago, as of right now the chevelle has pretty stock 402 and the jeep has a small block 400 running around 450 hp. I have decided to put the 400 in the chevelle I do however want to put a blower on the 400. I don’t want to build anything to radical and I don’t plan on building a 1000hp motor but I don’t want to drive around with a worthless blower either. I have never built a blower motor before but I was told this 400 had a blower on it at one time. Does anyone have any suggestions or know how much I should expect to spend?
