Can vouch for this motor... These blocks and heads were used in indy cars back in the day... 6 bolt mains held down a hell of a lot of boost. Chrispy, this conversion is screaming for a TT. I know someone you can speak to for custom manis and turbo kit... to put it simply, with a set of snails all you need to do is make 100hp per cylinder, which is not much for a v8 of its nature and hay presto.... Drags will become all too slippery!!!!!
