ALright guys i picked up the new summit magazine and they offer the lt4 conversion kit for like 2300 dollars!! not bad. But they claim 425+ hp. Is this true. the package is heads cam and intake. Has anyone done this conversion what numbers are u putting down? Also what times are u running?

 

I remember hearing that the test was performed with long tubes a bigger TB and some other things. I have never heard of anyone putting down those numbers with just the kit.

 

This is a post I put up a a couple weeks ago about the kit http://web.camaross.com/forums/showt...hreadid=175042
