i been reading and understanding this artical from hotrod mag.

How to Add Horsepower to GM's 6.0L Ls-Series Small-Block - Hot Rod Magazine


but what i am getting is the stock lq9 bore is 4" (or is it smaller) which is marginal for the l92 heads. i guess my questions would be how marginal? i do understand the l76 intake would need to be used or the fast90 ( wonder if theres any others) and some bracketery from a camero, none of this is not obtainable. can be done rather cheaply, anyway gonna read and research more into this as it seems like a postive route to go in... if its as promising as it seems..


anyway just some thinking out load and any input is more than welcome!!!!
