Solid Flat Tappet on Hydraulic Cam?
So its possible to do so but at what cost is what im trying to figure out. The only basic solid cam that summit shows is 1800-5800 and is 224/224 at .50 which would be a little slower with the 3.23 i would guess.

I don't know anything about Summit cams, but
a 224/110 cam will peak at about 5200. With a standard TF, it will want to rev to ~5800 on the 1-2 shift, ~5600 on the 2-3, and trap around 5400. I wouldn't want to run it with an 1800TC and 3.23s mind you. But a 2400 should be plenty of TC, in a streeter.
My 223/230/110 revved freely to 7000 with Eddies and 10.9Scr. I cruised that sucker in double overdrive at 65=1580, and she got 32MpgUS. That cam was a dump-it-and-go deal with 3.09x3.55= 10.97 starter gear. I mean monster SBM torque. She wouldda been fine with a lot less starter gear. But I had the overdrive, so it didn't matter.
Mine was a hydro cam, but a solid would probably make a lil more torque down low.
So I wouldn't put much stock in 1800 to 5800, except that at 1800 with street tires, you can floor it and get sideways right away. I ran a 750 DP on that combo, and floored it practically right off idle.
With non-Magnum iron heads I'd want a good 6 or 8 more exhaust degrees tho.
You know, I gotta tell you something; that cam was so torquey, I used to break the 295s loose with the line-loc on (didn't take much), and then idle down, and down, and down until almost at idle, and the tires barely rotating but moaning real sweetly. Or, I would crank the wheel hard over, slip the clutch out in second, and get the car rotating in 360s; again dropping Rs, until just above idle. What a hoot! Best cam I ever had!
I think you have to watch Summits tho, They do not rate their advertised durations, IIRC, at .008 or .006 like other cam companies. This does not affect their power because all cams of similar .050s and lift, are gonna make similar power, but it does affect the idle and cylinder pressure, AS COMPARED to other cams of same .050 specs. And any time you loose cylinder pressure off idle, you loose the low-rpm/low-speed torque.
I would maybe peruse some of the more popular brands like; Lunati, Comp, Howards, etc, cuz there you might find faster ramps or tighter lash designs. It kindof depends on how much Scr you have, to play with. My cam was Hughes, and was advertised as a fast rate of lift. I don't know what they mighta compared it to to be able to call it that, but it really wasn't that fast.lol. It was rated at .008 so not comparable to Comps which are .006,at least the ones I have looked at. BUt it didn't matter cuz I had the 10.9 Scr to play with.
If that Summit is a hydro, check out the advertised specs; they could be huge, IDK. That will kill some bottom end, cuz as you know the engine can't start to make pressure until the valves are on the seat and sealed.
But I think you know most, or maybe even all, of this.
Jus trying to help
