Internals will be fine at 200rwkw.

You want to change to a mild cam, like the Crane 2030/2031.

You will need to change valvesprings/retainers/locks, and pushrods. I would recommend you change to roller rockers as well.

Should get you very close to 200rwkw, and high 13 second passes. A higher RPM stall converter would help heaps as well.

Next step would be changing heads, and inlet manifold...or porting the stock heads and inlet manifold.

set of underdrives for it and a throttle body upgrade and some hi flow injectors should help you out but if u get the injectors you will need to retune it as the tune you have suits the injectors you are running at the moment



Holy Crap what was that, that my son was BLACK LIGHTNING!!!!!!
