If I could find it, or have it custom I would really like to try a TR220, but on either a 115 or 116 LSA, for sleeper idle. Then I'd want 2 to 3 degrees ground in advance, to bring it on a little earlier. I think this could be killer with a 2600-3000 stalll, so it could still tow. Any suggestions on where to find or have this made?

 

What additional things should i buy while i got the motor opened up to make this cam better and my engine last longer? I dont wanna break anything...

 

cam springs pushrods................
depends on the mileage i would look into a ported ls6 oil pump new double roller timing chain at least maybe milled your cylinder heads to bump compression just a tab.........

 

valve seals. they're about $24 from GMPartsdirect...may as well replace them while you have the springs off.

 

Thanks!!! Very helpful.
