I do have a 427 LSX was a bare block 376 bored out to 427 with LSX heads etc. Had it to the track twice and trying to work out the F'n gremlins
So I am keeping some options open like the B15, but last year when we spoke to folks at GM they don't warranty it for lets say 800-1000 HP so I wanted to see if anyone had one and beat the crap out of it yet.
I think C5 has thousands of members so lets say we can get 7700 members to send me one dollar each I will test it for everyone!
