If you want low rpm grunt, go for a 4.21 or 4.25 stroke, if you want higher rpm power, go for 3.75 stroke and if you want somewhere in the middle, go 4" stroke. Cranks are available in all flavors, so start with a good 400 block and you can have whatever you want. Ideally, a 4" stroke 6.8" rod combo would be what I'd build if starting from scratch...

i am actually not sure as of yet....my Dad & I are planning on getting a 79 T/A by the beginning of this summer...my intentions is to get the biggest engine i can possibly fit into the T/A...on a post earlier somebody said i can fit a 468 stroker into it?? now my question is it's a 468 CID with a bigger crank?? and ummm...i jus want somethin' under my hood that roars even when it's idling....so maybe toward the middle...as soon as i get it & we start workin' on it, i'll be sure to post pictures & ask questions more often on this site...
