Default what to expect...
I bought this cam out of the classifieds

I had a 6.0 but it needed more work than I wanted to spend (spun main)

How would this perform in a 5.3?
Vic jr 750dp
4k converter
Spray.

Should I rethink my 6.0 or find a new one?
I currently have 2 sets of heads 317 and 806 (ls1 early)

That is alot of cam for a 5.3!!!! Is it a all forged setup? Your going to have to spin that motor high and have some decent heads.

Why not make your 6.0 a 400+ ci with forged bottom end?

That is a split hair bigger than a Trex. Will be great in a 5.7-6.0. For a 5.3 it will want to spin more RPM than the rod bolts will want to allow.

If I had the money for all that, do you think I would be looking at used camshafts?
