I was thinking something like a 222/226ish with something like a lift somewhere around the .570 area. I'm running a 3k stall currently.

I've looked into the 6.0 route, around here you can't get one with less than 150,000 miles without spending $1200-1500.

I don't know if I want to use the stock heads and mill them a hair for a bit of a compression boost. The 243's on my 5.3 are 60cc chambers, but I think that'll be too much compression, either I'll mill the 241's, or swap them out with the 243's and run thicker gaskets to offset the smaller chambers.

 

60cc head on a ls1 is 11.27 to 1 with stock head gaskets
Dont be scared people run 5.3 heads all the time on ls1 motors.
yours vs stock 61.15cc 5.3 heads is only a small gain in compression

or you could run a thick gasket or -4cc dish pistons to lower compression.
-4cc dish piston would be 10.7 to 1

 

I ran a set of milled down 5.3 heads on my ls1 in my old camaro with stock gaskets.... dont be a baby!

 

243 heads with 60cc chambers? Must have been really milled, stock they are 64.5cc

 

Milled .030

I guess even running around 11.25 CR... the cam will bleed some off too. I was just concerned running such a high CR if it starts to use oil. This is a DD truck. I think when I get the motor I'll run it up to the machine shop, have them put a fresh crosshatch in it, put the rotating assembly together, and new bearings.

I think this cam with 1.8 rockers is close to what I'm looking for. I'm on the fence about getting a Pat G cam. Not because I don't think he knows his stuff, but just because of how busy he is and the wait time.

 

man idk that 222/226 has proven its self very well
Many guys on ls1 tech have broke 400hp easy with that cam
Have you seen the dyno sheets ? I was very impressed

 

No, I haven't seen them. I haven't really looked at many cams yet.

The 222/226 is an EPS lobe isn't it?

Nevermind... Found it. I'm thinking about going with beehive springs since this is a DD, or am I better off with getting a set of duals?

 

yes EPS
i would run duals with that cam

 

Another vote for dual springs. You'll be pulling some high rpm with that cam.
