I had aloy of help with my build. And as I was reading the spec sheet that my builder gave me I saw the final compression to be at 8.6 to 1. I for some reason had the 9 to 1 ratio in my head and spoke with the guy doing the final tuning and told him it was at 9to1, so he was making me aware of the situation. But I'll be fine with the ratio that its at. I'm new at this and I'm trying to absorb all the info I can. I appreciate everyone taking time out of there day to spread there knowledge. I rebuilt the motor it has 100k and it wiped the cam. I have a 49 turbo wth injectors alky kit bigger down pipe, custom radiator ,scanmaster, hotwire and pump. 218 cam full roller Harland sharp roller rockers. Everything has been replaced. Still have to get tranny done and figure out what stahll to use.
