Hi Everyone, I was wondering if anyone has ever used one of those plastic set-up motors? {made by P-ayr Products, www.payr.com } Are there any disadvantages to it? {other than the fact that it doesn't run! ;).. I want to get a hemi one before I get the actual motor to see what I'm getting into. Plus while I'm having the engine built I can work on getting it to fit! Thanks, Bill
