Hello I am interested in swapping my stock 350 vortec with a 5.3 (i threw a rod through the oil pan on the 350) Furthemore i pulled the original and recently discovered it is nearly impossible to find a used 350 without a million miles on it. I found a 5.3 well worth the $$ just a little reluctant to all the conversions such as motor mounts, A/C, fuel, and electronic crap

Thanks a million
Erik
