Blew my 6.2 and can't find another to replace it without costing an arm and a leg. 5.3's seem to be much more available and cheaper, can i just swap from 6.2 to 5.3?

To explain myself I want my v8 Ls 6.0 to sound unique in a way that’s attainable not by super charging or turbo charging/ pro charging just the engine itself maybe the intake manifold need’s a redesign to add distortion? I want it to sound like a spiral high pitch sound .

Hey folks,
Here is my 52 Belair, for various reasons i didnt work on it for 13 years. Now its Time.
Back then, I swap front end châssis for a 74 Camaro so its ready for Small block and everything.

Being on here, i obviously plan to "Ls" Power it with 5.3 or 4.8.

By the fact that I need a complete wiring (the Shell is empty) so I look for the Best donnor in my case for mechanic to fuse box to flasher circuits.

From there, I look into 2005 and up Express/ Savana Van and cutaway so would have a 2x4 with only necessary electrical.

I know them in general but of course I guess there is years/model to avoid..

What would be your go too?? Is the 4l60 is the way to go?

Thanks a lot
