For a street car on pump gas ,thats not too bad. But for a full blown mod, thats not even close.
To be competitive, you need another 150+hp on tacky tracks.

Hpontap is correct. I have one of each motors you are talking about. The 388 makes around 650 and the 358 around 630. Both have good pieces in them so they will live.
That being said there are guys that are real fast and do not have high power, but it never hurts to have extra if you need it.

i think it depends if you're running imca or ump. 525-550 hp in imca with the harder tires is probably plenty.
