typical cost of 5.3 swap in obs?

Basically, realistically, its not practical to install an LS engine into an OBS truck, UNLESS...its your baby, and you plan on keeping it for a number of years. It can get costly due to the extras. Its not a plug and play, by any means. Its much easier to rebuild or replace what engine you have. BUT...the all-around performance of an LS engine is night & day when completed.

Owning an OBS isn't practical period. They don't have or gain good resale value no matter what you do to them. I don't think anyone who owns an OBS (especially those doing a motor swap) are thinking practical. If you want practical go buy a geo metro.

I agree 100%. Even though we all love our LS conversions & would'nt have it any other way, anyone that hasn't done one, but is going to do one, really doesn't know yet, how many little(and sometimes costly) extra's come into play, that you won't see in a conventional engine repower. So many new LS conversion guys come on here to proudly(rightfully so) tell us, or show us, their LS progress, an say: "Well...I started this project 6 months ago, and I'm finally just about to fire this bad-boy up". lol Cracks me up...cause I know exactly what they went through to get it to that point. And chances are, they STILL have to install exhaust, intake snorkel, gauge wiring, etc, lol. All this, when the old 305 engine could have been rebuilt/replaced in a week-end, lol. But...Is it worth it? Oh Yeah! It sure is.

I love my swap and would do it again.

flattopwill...I listened to your video & like the sound of your exhaust system. What exactly does it consist of? Thanks

It is what's in my sig with dual 2.5" pipe coming off the headers into a Y then 3" pipe into a single in dual out Flowmaster with turn downs under the front of the bed. I love how it sounds as do most but if you are looking for quiet don't go this route (I remembered your earlier post about mufflers). It's not as loud as say a "bullet" style muffler but still pretty loud and resonance is horrible from 1500-1900rpm. Also, I think this muffler slightly disguises the chop of the cam. Other wise, I love it.
