What year 360?

I actually have to correct part of my above statements regarding one of the motors I mentioned. I talked to the guy at work with the 78 360 and he said he is running 10:1 compression TRW forged pistons with a 60 overbore and fully ported and decked heads. He is around 450hp with a stock 360 crank.

350-450HP is very achievable using the stock crank with the right combo of parts and of course it has to be built right! 500 HP is also achievable with the stock crank and will still be streetable.
