For the added noise of a blower.
Could do a gear drive timing set if they are offered???
Noisy whistle whine as all get out. Had one on my
SBC back in the day.

Let me know if I can do anything for you.
Precision 76/68 would standard.
76/75 is an upgrade option.

 

Whats the difference between the 76/68 and 76/75? Im a turbo noob. Will my walbro 255 and ls2 injectors support 6psi of boost?

 

The exhaust wheel size. The 75 flows more.
Decreases back psi.

Not always needed depending on goals.

 

Looking for 500 at the wheels if my pump and injectors will support it. Then ramp it up ftom there. Looking to use a brian tooley 226/231 turbo cam.
