My dad and i recently purchased a 52 1/2 ton chevy pickup to restore. i cam up with idea to put a stroked 6L instead of a big block in order to have something differant. I am unsure of where to get the rotating assembly and how many cubes it will go. Any experience or help is appreciated

 

6.0L will go to 6.7L (408ci) easily and can go higher with special attention.

6.0->6.7 = 6.125" connecting rods, 4" stroke crank, 4.030" bore (30 over)

1slowZ71 put in a 4.1" stroke crank and went to 418. I think his bore is the same.
Benkey is at 410 (412?)ci with 60 over and the same crank and rods.

With more money, you can do a 427 out of a c5r block.

 

ya i just read the whole 1slow01Z71 post and all of his problems with the crank and clearence issues. is it worth doing the 418 and what kind of hp and tq # could i expect properly cammed and tuned

 

NA? high 400s low 500s, I think, depending on all the standard variables.

I wouldn't go through what 1slow did. He may have a different perspective, but I'd do a 408 and a power adder if you still want more. I don't think 10 extra cubes are worth what he had to do, but now that he's got it done and you have a guide book of sorts, it might be easier.

 

Hi, I also have a 51 Chev 1/2 ton step-side with the wrap around windows. I have been considering my options for awhile, I will most likely go to either a Big-Block or Small-Block. My honest opinion: putting a GenIII into an old truck is costly and time consuming. You can get away FAR cheaper going carbed.

But it would be awesome having a one-of-a-kind like that.

Different Strokes for Different Folks!

 

I will agree with you in the fact that it would be more costly to put a gen III into the truck considering we have a 2 big block blocks sitting in our shop along with a few small blocks. The point is to be differant and creative no one gets better by doing the same as everyone else
