well as many of you might know from all my stupid posts, but i have a 350 with a 327 crank in it but it still has the 350 top end in it, i have been told this was done to get more hp at higher rpms, but all it seems to do for me is suck through my gas faster than my buddies 400 hp engine and it seems to hate speeds over 50 or it will blow up, but i have been thinking about putting a 350 crank back in it, but i have been wondering if i will have to get new pistons, will i need to get shorter ones or not, they are nothing special, just .060 over forged steel, aside from that i don't know anything about them, but i don't think i would need new ones.
