It is a lockup converter, Tranny cooler. 3.90 posi rear end. Approx 4000lbs including driver (gathering parts to swap to a T-56 6speed trans)

**-Gen I SBC, 4-bolt splayed mains, 1 piece rear main seal, OE-Roller block, 0.030" Bore, "0" deck.
**-Canfield Aluminum 195cc, 65cc CNC chamber, 2.055/1.60 or considering AFR 195cc Eliminators with 65cc chambers.

-Scat cast steel 383 stroker crank. 3.750 stroke
-5.7" forged I-beam rods
**-SRP Forged flat top pistons, -5cc dome, 1.285 compression height, approx 10.89 static compression ratio, 8.42 dynamic compression ratio, 445 grams
-Balanced rotating assembly (Internal balance)
-Comp Magnum Hyd Roller 286HR cam, 230/230 dur@50, .596/.596 lift with 1.6 rocker. 110LSA, 106 intake centerline, approx power range 2500-6000.

-FBO systems Built HEI distributor with MSD 6-AL ignition box (multi-spark) with 6250rpm rev limiter chip.
-Oil cooler with filter relocation kit (Dual large filters) Makes it about a 9 quart oil system.

Considering the XR288HR cam part number 08-433-8
236/242 @ 50
.555/.576 lift with 1.6 rockers
110 lobe sep
106 centerline

I might have to drop the compression a hair to use this without pinging. Tell me what you think about the cams. Suggest something else? I want to hear. Should I advance the cam a little? Remember this is an all street car that weighs 4000lbs. I would like a decent sounding cam but im more concerned with function. I've thought about going with a 106 lobe sep but i think id have to lower compression more. Im open to ideas.
