Supershark kit. Without a doubt. Do some research on rennlist on it. Definitely go supercharged. There are guys running theirs at over 600hp and over 200mph. You arent going for a “most power” setup anyway, take a look at rebuild costs doing it the “right” way for an 32v motor (or hell, even the 16v). Just supercharge it at 8psi and call it a day. 400+whp reliable.
