Default Re: Porpoising Seavette

Steve, I don't think a Paxton blower on a high compression motor will work well. My brother had an underdriven Paxton on his '76 Mustang II Cobra. It worked well enough until he had his heads milled and rebuilt the valve train and installed new dome pistons to obtain an 11.25:1 compression ratio. (At that time Paxton reccomended a max comp ratio on the stock Ford 302 of 9.5:1)
His crankcase pressure was so high at high revs he would blow immense quantities of oil out of the breather, and somehow he eventually hydraulic'd the motor with oil blow-by , and had it come apart completely. It even blew the oil pan loose on the bottom.
