Mighty Mouse ran mid and low 8's in his 3800 lb turbo car for years with a Erl block and a stock crank out 20k miles on it also in that time.
I mean thats where about I'm thinking I will end. Probably dead on around about a 1000whp. I'm sure I can make it stock cubes and I like the 6 bolt heads that come with it but maybe its more cost effective to put the right components in the LS3.
I was looking at the B15 strongly or buying a shortblock from TSP. I'm up in the air but the stock stuff is taking a beating so far so I'll keep it moving.
