Shouldnt need to touch internals as long as you arnt going over 7000rpm, theres talk of even 7500 being ok but i think thats pushing it a bit

Thats enough headroom for some half decent aftermarket cams

I know of a few people running up to 8000rpm on stock internals. Not sure if this is wise though.

yeah im at the point where, do i really want to spend the extra money for the shim under bucket conversion to run big cams. Then will need to change to aftermarket rods and might aswell higher compression/head work while im at it and have 8500 to 9000rpm of love.

or

run a more mild cam within the limits of the engine's rev range and not have to worry about rods/shim under bucket conversion, though there still be a risk of how long it will last i guess.

Either way i would want to at least crack the 300rwhp mark (do-able with mild cams+head work?)
- though if i went all out on doing the above then more closer to the 400rwhp mark would be nice.

Looks to be running a tad rich ? Mid 12's afr's are perfect for forced induction, possibly run it up to 13.5 with NA ? That could help it rev better as well ?
