Wow great info thanks to all that replied
Not looking to boost it well not to start

just looking to keep the cost down. Really want to come up with my plan see how much it will hurt the budget and then go from there.
As for the motor I just want freshen it up and of corse get the most out of it. It's a street car so I'm not all that concerned about the 80lb difference, I'm sure the iron block setup is about the same as a SBC, or close.
As for which one I think I'll look for an lq9 as it would make alittle more power with the right cam, heads, and intake?
Here's another question, I want to run the carb intake, maybe even start with a carb? I was thinking to run a set of L92 heads as they seem to be a real good lower cost option and make nice power?
I guess what I'm asking is what would a good setup be for the lq9? Carb, cam, heads, and intake?? I may run EFI later but for now to keep the cost in line I thought a carb setup would better on the budget?? Maybe I'm wrong in my thinking???
