Hello,
I have been away from the hobby for awhile & have decided its time to build a motor. What I have is a 396 +.060 or a 402 + .030 (whichever you prefer). I have a set of TRW L-2287 pistons (floated w/considerable domes), 3/8" rods, & a steel crank. I have a HV oil pump and cloyes timing set. I picked up a set of 336781 heads w/bowls cut for larger valves & have both a Torker & Victor JR. intake. Naturally I will be using a Holley carb (probably an 850 DP). I will be using this in a 3200 lb car, auto w/stall. I'm looking to go high elevens or low twelves, and am looking for advice on camshafts. I don't really want to go the roller cam route, but might. Any advice most appreciated. Thanks, Brian

Brian you could call the various cam companies and explain what you are looking for and let them make a recommendation.

single plane manifolds and over-size carbs are not a good combination. Try a Performer RPM and 750 vacuum secondary.

go to a roller cam is there's any way you can foot the bill. Many, many problems with flat lobes lately, feds have eliminated one of the critical components of motor oil because they they think it poisons catalytic converters and quality control issues with some cams. They don't care about those of us left with flat bottom lifters. This problem is not going to go away. search this section and the performance section for "flat lobe" and read the sticky topic about oil at the top of this section.

BTW, your engine actually needs a little under 700CFM at 7000 RPM, if you run it that high. 850 double pumper and single plane intake are going to kill your bottom end and mid-range torque. Think in terms of 1 and 3/4 or 1 and 7/8 headers.

Compression ratio:

* Cylinder head Volume (CC) = 118.00
* Piston Top Volume (CC) = -39.00 L-2287
* Cylinder Bore (Inches) = 4.165
* Cylinder Stroke (Inches) = 3.75
* Deck Height (Inches) = 0.020
* Head Gasket Thickness (Inches) = 0.039

Computation Results:
# Computed Compression Ratio is 10.0 to 1
