ok......i didn't blow the stock motor after 10,000 very hard driven/overboosted miles......but i went ahead and got a sleeved block with 9:1 cp pistons now. 377whp, 333wtq tuned @ 20psi on 2.25" exhaust with a 60-1........but now i have a 3" exhaust and SC61, so i'll retune soon with a little more boost and should make mid 400's if the stock ignition will let me.
