I consider myself an enthusiast, but I didn't really have many specific goals. Moving from the Dom1.5 I just wanted more power and similar spool and street manners. I read about the GTX and Perrin's big post had recommended the 3076. I'm very happy with the choice.
As for heads, didn't want to be making monster monster power, and didn't want cams either since not much showed me it was really worth it for my needs: street daily driver. And stock exhaust because I prefer quiet, and inconspicuous when I'm flying down the road
I'm sure with just an exhaust and rev it out to 7500 I'd hit 600whp. I want this to last, and didn't feel the need to change the oem rev limiter, and Ron didn't suggest it either.
