I'm looking to swap out my 5.3 with an ls3 in the next couple months. The previous owner of my truck dumped bucket loads of cash building this truck. That leads me to a what I hope not to be a predicament. I have a magna charger, which is a Whipple style charger, on the 5.3. Will this supercharger fit on an ls3? Are there any other components I will have to swap along with the engine? Thanks in advance for any answers or advice.

 

Yes and No. 5.3s had cathederal ports and the LS3 has rectangle ports. It can work but u would have to change out the lower half of the supercharger manifold to fit the ls3 heads.

 

Thanks for the reply. After searching around this forum, I assumed that would be the case. Thanks again for taking the time to drop a line.
