gen 3 motor ?
I have a 03 5.3 in my 80 k5 blazer. Recentlt blew up engine. I happened to have a 08. V8 motor on hand. My question is if the newr motor would work in replacement of the 03. I plan on just using the motor and heads. I noticed a few sensors where in different locations.

Agree with BCZEE. You will have a 58x reluctor in the 2008 engine. You can either change the reluctor or use a lingenfelter box to convert the crank sensor from 58x to 24x. What size is the 2008 engine?

Why waste money on a expensive conversion box are removing the crank just to swap reluctor wheels as change campick up as well, just to run a 4.8L. Get the right motor.
Just look for a Gen III 5.3L long block 99-06 and carryover 2007's to replace it. Search car-part.com
