I planning on swapping a LQ4 into my 97 Stepside Z-71 when I get my tax return next year and I'm trying to educate myself in the mean time. I want to put around 500hp the the ground but I need it to be streetable at the same time. I know that it is very possible I just am not sure what would be the best(cheapest) way to go about it. I would really like some input from some of the guys that are making that kind of power to see whats working best for you.
