no funny replies now. what is the stroke of a 6.0 and an ls-1 stock crank? something like 3.84" or something isn't it?

 

5.3,5.7,6.0 all have the same stroke. 3.622"

 

you sound pretty sure about that. so the 4.8 is the only oddball? can you put a 4.00" crank in without any other mods?

 

Nope. If you change the stroke, you have to change the rods and pistons to match. Basicaly the complete rotating assembly.

You could install a 5.3 crank. rods and pistons to fit your 4.8 block.

 

hey tex. not the 4.8, the 6.0. i may just have to deal with the fact that i will have to keep this thing. i was talking more about having to machine the block to accomodate the additional stroke. anyone know of a kit for the 6.0's?

 

Hey Texas Terminator,just a suggestion, if i were you i would offer big Tex to come over to you crib along with several beers and pick his brain for knowledge in all the interchangability and maybe come up with a solution to your dilemma.He has a lot of parts you need and maybe able to come up with some sort of trade thats workable for both. His no-how might be worth alot to you.

 

yea, right on. i can get a new crank out of the moron i got the motor from, but that still doesn't solve my heads issue. all the parts are new, i am just exploring other avenues. the motor is already out after all.

 

What is wrong with your heads?
