i did a search on 427 tall blocks, found alot of info, found some answers to questions i had, i was thinking that I'd go with a 4.375 stroke use 6.535 rods maybe have to do a small amount of grinding ,bore the block .060 over stock, (about 510 cubic inches) thats about as far as i got in planning, I plan to put this engine in an 85 4x4 lifted chevy truck 4 speed manual trans, i would like the engine to be streetable,run on pump gas and sound pretty mean (lopy idle) i have a set of 781 heads i wanted to use, just wanted to know if anything is wrong with my plan so far and what you guys thought? how much horse can i get out of it?i might do some comp. truck pulling with it.

Thanks
