I got this LG4 block with 601 heads and an energizer chs278h10 cam in it. Will that cam and those heads fit on my LO3 thats in my car know. I know my TBI intake wont bolt up to the heads. Is there anything else I should know. Or or should I just drop the whole LG4 block in the car? Any idea on how much more power those heads and cam will make on a mostly stock LO3. It has an open element, no TBI spacer, shorty headers, the rest of exhaust is stock right now.

 

imo just drop the lg4 in there its all ready together why not ya know.the LG4 is allready setup to run the cam right?

wouldnt the lo3 be a roller block.

 

I was thinking the same thing. But I think I may need to change the cam bearings and I have never done that before, so I was just wondering if I could put that cam and heads in the LO3.

 

Why do you think you may need to change the cam bearings?

 

The front one has a big scratch. I think one of the middle ones may be scratched up too. Cant tell for sure until I drop the crank.
