so i have a couple questions bout the gm 847 first does it need bigger injectors, what size throttle body, about how much power will i get out of it, and can i use 1:6rr with stock valve covers?

 

tRY A SEARCH, BRO. aLL YOUR ANSWERS ARE THERE.

 

1. You will be fine w/ stock injectors for now.
2. I would up it to a 52mm TB
3. Every car is different. Depends on your supporting mods.
4. 1.6 rockers will work with stock valve covers.

 

If your going to make in the upper 300's to lower 400's its not going to hurt to go to #30's for the injector, the car needs to be tuned anyway so why not spend the extra couple of bucks.

52 or 58mm doesnt matter they preform about the same, the diff is you need to open up the intake manifold

 

well i made 353 rwhp and 374 rwtq w/ the gm847 cam w/ the stock tb....
and if ur interested in buying a used gm847 cam(only has 3000 miles on it) PM me
