Im going to need to look into a new block as my compression test didn't turn out too good...haha, but I was expecting it. My current setup is a rotated GT3071 setup pushing about 425whp on 112oct. The car is not dd at all and it is mostly setup for autox (hence the choice on the turbo, which is perfect for autoX in my opinion). I will be the first to tell you I don't know a whole lot on this subject, but I am becoming more learned. I am going with Ron @ RAW1 for sure, since he's local and super nice guy. I really would like to keep it under 5k, maybe 6k. Im looking at his track series engine, there is really no need to sleeve for the power levels Im looking at right? Or, would I be better off with his street block and re-work the heads also? I would imagine the higher the redline would work the best for autoX. Just want to hear some of your guy's opinions. I have an appointment to talk with Ron this week, but I just want to be a little more educated before I make a decsion. Thanks in advance
