Thinking about going with a 2.75 inch pulley. Too much for a stock motor?

[QUOTE="Scott8583, post: 14910475, member: 163420"] I ran 11psi on my stock motor for most of last year. With a little race gas mixed in I ran 10.60's @ 131mph... Some people push the stock motor above 11psi to try to run 9's. Most of them plan on building the motor anyway, so if it blows it's not unexpected... 11sec_lx has gone 9.90's @ 138mph this year with just cat deletes from Jegs & GT500 mufflers... [/QUOTE]
