I haven't actually put the cam in yet. I just have it sitting in the garage. What all will I need to add when I install it? Push rods? valve springs? I was checkin out parts on thunderracing.com and I'm not sure what to get

edit: I think I'm just going to ditch the cam I have and go with a new kit. What size cam would be right for my setup?

 

damn nice ride. good luck with the setup

 

Thanks guys!

 

The 220/220 lsa114 has the biggest negative overlap of all the cams offered in the thunderracing kit. Would that be a good choice?

 

Or would a GT2-3 cam be better for boost in my 4.8?

 

Quite a few people run the gt 2-3 with great results. I think it would perform better than the tr 220 in a boosted truck.

 

That's not enough cam... stock cam or a Leading Edge Performance stage 1 blower cam. That cam is proven to make the power. Im running 12psi on a stock bottom end, stock heads, and stock cam and making over 650 to the wheels... If you are staying at moderately low boost levels, (below 8psi) your stock bottom end will hold as long as your tune is good.

 

for a 6.0 it may not be enough, but the op has a 4.8.

 

I want one that will help get all the power I can out of the blower but not be too aggressive. This is for a DD after all. The gt2-3 will cost a little more but if it's worth it I'll get it.

That's way too extreme for what I need.

Exactly. If I can get at least 400 hp to the wheels I'll be happy. I don't think that's asking for too much

 

Could my engine produce more power with a different camshaft, quite possibly? However, for a daily driver that runs 12.04 with what everyone says is the too small Radix MP-112 and 11.67 with a 75 shot in a 5650lb behemoth, all the while idling silky smooth and being gentle on the valve-springs, I don’t know that I would go so far as saying it’s too small. Maybe too small for max performance, and maybe too small for a supercharger that could push a little more air, but I don’t feel it’s too small for the 112 that’s doing all it can. And I know mine isn’t a fluke, as there are a few that are running similar times with basically the same set-up. Too bad the GT-7 is no longer available, as it showed promise as well and Roger’s (KySilverado) truck also ran almost identical times. I know the LS9 has comparable enough spec’s that Lingenfelter dropped the GT-7 as a cost savings, but due to the amount of effort and money it would take to convert to the Gen IV style timing components, front cover with CPS and the extension harness that is also required, I don’t see where it’s really the best choice for a Gen III equipped vehicle. Now if the OP had a lighter weight vehicle with smaller wheels and tires, with a larger more radical combination, I could see going with a more aggressive camshaft, but as it stands, I feel the GT2-3 should work as well in his as it does in everyone else’s. Another good thing about the mild GT2-3 is that while it will set you back a little purchasing it new, you will be able to run the LS6 valve-springs and could get away with the stock pushrods as well if you desired. Better pushrods are always a nice upgrade when you increase spring pressure or extend the operating range of an engine, but at this level it’s not 100% necessary either.
