    would this cam fit a 5.3?

    saw this cam and am curious about it, would it fit/work right in a stock 5.3? of course i know new pushrods and dual springs and tune would be a must along with bigger injectors. also how would it perform? and what size stall would be needed? 3200?

    It would be great midrange and upper range. It is a rather large cam for a 5.3, but it isn't massive. That cam works extremely well in the LS1. I wouldn't go lower than a 3400 stall with it.

    Of course it will fit. You can run 0.600 + lift if you want. What is the LSA on that cam?

    well i figured it would fit cause i read you can run UP TO .640 MAX but then again ive never personally saw a 5.3 with stock heads and block with anything over .600 so i wanted to double check before i looked any further into it. you pick the LSA when you order

    Just don't plan on running boost with that cam. Even with a wide LSA, that is a lot of duration.

    I dont know that I would say Dont plan on boost with it. The cam that was spec'd for my turbo engine isn't too far off those specs as far as duration and lift goes.
