My 360 build.

I currently have a 230* cam in my 10.7Scr Eddie-headed 367. I run a 3.55 and an A833 with a 3.09 low gear, and a GVOD.
The starter is 10.97, the cruiser is 2.77 with the overdriver making 65=2240.
Second is 32@2710, so I ain't fooling anybody. But I also don't have to downshift.That 367 at 185psi just lights em up.My car is over 3650 with me in it, with about 48% on the rear.

With the 2400TC, I'm liking the 223 cuz it makes even more low-speed torque for that A500. At 10.8Scr, an easy target, the pressure will be close to 185, and the VP will be big-block like at over 160VP. With the 11.78 starter gear, he will be putting more footpounds to the pavement than I do,and mine lites em up easily,at less rpm. And I have made fuel mileage deep into the 20s USg with that 223, and a nearly 50 year old Holley 600VS.
But if Cley was willing to go with a solid, then yes a bit [email protected] would be a treat and the Scr could go down a little to maintain the cylinder pressure. But you can't go much lower than 223, cuz the pressure is climbing fast...... unless you order a long-ramp cam. My 223 was advertised at 270/280/110. I didn't measure it.
That 10.8 is just flat-tops at about .011 down, the 63cc heads and the .028 gasket. Easy peasy, and with Q of .039. Can't get much simpler than that.

My combo was set up to run 10.7/11.0Scr with just a gasket swap........ which is what I ran with the 292/508/108. When I switched to the 223, I installed the .039 FellPros, to keep the pressure around 185. But now, with the 230 cam, the pistons are .005 out of the hole, and the Scr is set up to go 10.7/11.0 with similar pressure. It's still more than the tires can handle. But once past 85, things settle down for the long haul.
