t60 or t67 Having a forged 347 9.5/1 compression built. Going w/ZO6 cam stock heads. My question is to make 500-600rwhp should I upgrade my t60 to a t67(STS kit). Current mods FMIC,Mac headers w/ORY,ASP pulley.New mods 42# or 60# inj.(not sure yet) and ZO6 cam & springs.
Id suggest LQ9 heads to lower the compression a little bit. If your setups not done yet also consider 918s and possibly a LPE GT7 cam. Then you should be able to run 9-10 psi on a safe tune (if your FMIC is decent) and make an easy 500+rwhp on a 60 trim. I believe theres a few on here that have made 550-600+ on their 60s before swapping to a 67trim
edit: btw go for the 60# instead of 42s. theyll start to run outa steam after 550hp. May as well go bigger from the start.

Go with 60# injectors... and with the 67.... the 60 will not give you 600RWHP in an STS setup. It is cheaper to take your 60 and have it upgraded with the 67 wheel... dont buy a new turbo. If you want to buy a new turbo... with a 347 I would reccomend a 70 or 72.
