stock block with forged internals i know for fact can make 660 RWHP

But its not wise, even with internals.. i think its wise to stop around the 430 RWHP area on a stock block stang.

My 306 is the same as a DSS essentially, and its been hammered on a few times.. If youre going to spend big cash on the insides, might as well get a block too... then make 1000+ RWHP

routine maintence and still **** itself.

yea i herd shaggy is a little rev happy

all the girdle will do is hold your parts when the block splits.If you don't beat on the car 24/7 it will last you.I have friends with 500rwhp and so far so good.you will be good at 475 rwhp..I say just go the 500..a fresh stock block with internals is a $1000.00 so don't worry.500rwhp is good for 10's so why would you want more than that on the street.worry about the stock 8.8 and stock trany..Dasilvas son is runing 600 with a 306 and he gives it all its got.his car has 2.02 edelbrock heads cobra uper/lower and 12lb of boost with a good tune.

O ya don't forget to spend the money on ARP bolts..
