Tuning my 360 la motor
I have the same crate but pulled the cam for a 268/280.
Beauty Duster!
:popcorn:
A 268/280/106 Solid-lifter flatty, together with an Scr of say 10.2;
this would make a huge difference in Cylinder pressure at 4350 ft elevation.
And, at an Lsa of 106, the Overlap would still be significant enough (62*) to make her a ripper after the torque peak. The Wallace predicts 161psi. With iron open-chamber heads, this is about as high as you want to go, to be free from detonation.
And with such a cam, OP can keep the 3.23s. Still no where close to ideal, but it's hard to argue with 65=2600(with 27s). The clutch will make the 3.23s bearable.
--------------------
When I pulled the 292/292/108 out of my 11.3Scr alloy-headed 367, I opted for a similar Hydraulic cam; 270/276/110. The pressure rose to over 190psi, and overlap was still 53*.. That was my favorite combo ever.
Sure it nosed over early, but with 3.55s, this wasn't noticeable until over 70mph, and the car still went 12.9@106 @3650 pounds, on 245/60-14 street tires, on the only timed run it ever made.
I was very sad when the cam started dropping lobes.
Plus, you know, she ticked over at 500 rpm, just by rolling the timing out....... and leaving the stinking transfers alone.
-------------------------------
You know, Ima thinking our hot-rods should have a choke-type cable hooked to the distributor, so that the timing could be varied from the driver's seat, in the range of say ....... 15 degrees, lol. just like an old John-Deere tractor. I think I'd like to install mine on the side of the shifter.
I'd set mine to get from 6* advance to 9* retard, from a baseline of 14*.. giving an idle-timing range of 5 to 20 degrees. Hyup that should do it. I think the device should be infinitely adjustable over that range, but steps of two or three degrees would be fine also; and it needs a simple lock on the outboard side of the rack to keep it from slipping, and a robust positive anchor on the inboard side, so that it will stay put on the shifter. Ima thinkin aluminum body/steel lever.
If someone was to to whip one up, I'd be willing to review it for you. I'll even provide a napkin drawing..... we'll make mucho-dinero. I already have a brand new cable.................. lol.
