Supersixmotors test the 4.2L stroker with an 8.5 compression with 20lbs boost and made 600 plus on the engine.
One of their engines take abuse all the time with some ridicules 200+ nitrous
shot and runs into the 10s.
I hear the 3.8 blocks are hella strong and can take one hell of a beating, just make sure everything is forged and ported, get good bolts, and don't skip out on good push rods either.
I'm looking to do the 4.2 stroker with a pro charger at about 10-15 lbs.
I wouldn't do the m112 cuz you can't intercool in in the sixxers. And turbos cost 4k and I've heard of ppl spending another 4k just to get the tubing right.
