Building a reg. 4.1 NA Block instead od a St. 2

[RUQWKNF27]

The guy who has the turbo Cadillac CTS in the curreant GM HI Tech says he has done this 4 times with great results, for his turbo cars. Basically saying there is no need to go with the S 2 blocks. Has anyone heard of this being done else where..????

The guy with the CTS is a buddy of mine, 4.1 is by no means as strong as a stage block. The key is not to detnate no matter what you build. Yes the 4.1 in his Caddy is holding up pretty good, it is just like the 109 block( maybe weaker maybe stronger) but will give you more cubes. So far the best the Caddy went 11.40's @121mph on nitto drag radials and dynoed 430rwhp. He should be going back to the dyno next week with 4 bolt exhaust housing and 65lbs injectors. we will see.

Good luck
