Like the title says. For a 4" stroke: LS7 $713 (partsdirect), Eagle $780 (sdpc), Callies $1600 (thunder).
Does it make sense to use the LS7 crank, machine the nose and swap reluctors? Should be better quality than the eagle, but alot cheaper than callies, lunati even after machining and reluctor swap.
Thoughts?

Has anybody done this?

I thought of doing this but I had already gotten the Eagle crank balanced. However, I'd bet that the Eagle crank can handle more power than an LS7, not much more, but more.

Don't forget the LS7 has a pretty light rotating assembly, you will most likely have to add heavy metal to it to make it balance. I haven't had to add metal with the Eagles or the Callies cranks. I have had a LS7 crank snout shortened and swapped reluctor wheels, it turned out great but if you are using a forged rotating assembly it will end being a more expensive endeavor, plus the LS7 is 4130 all the others are 4340.

That is correct, we used the stock LS7 rods and crank. These are issues to consider, most haven't done it first hand so these are the potential things you may run into, just trying to help. Dave

If I recall correctly when I built and up-graded my 4L60E to a 4L65E+ I bought new OEM 5-pinion planets and a new OEM Borg warner 29 tooth forward sprag and they were all made in China. I couldn't believe it but I do think that's correct.
