With teener manifolds; you gotta go easy.
In a 64 you don't need much.
If you are picking a cam for attitude at idle, um, you may be sacrificing things to get it.
What cam? IDK, but:
If I had a 64 with manifolds, I would seriously bump up the compression, and put a teeny 340/360 type cam in it.And like said; put some springs on it, so it will rev to 5800 reliably. I would put monster pipes on it all the way to the back.
That's it.That's all.
Then I would put a 4.10 SG in the back, with some serious traction aiders.
And a 2400 to 2800TC.
Then I would go out and pound on it.
I would have the quickest zero to 60, teener car around.
I agree with Rusty, I would get a custom cam.
With a 5800 shift-rpm I could have some serious lift. I would be looking for a power peak around 4600 to 4800, and a power band of 2400rpm to match the automatic.With 4.10s second gear cruise at 30mph will be around 2350. No one will be suspecting anything. But when the hammer falls, the Rs will climb to 4000, and I will be blasting off to a 44mph shift, and second will be passing through 60 at 4700( right at the hp peak), on it's way to shift at 74mph. Then third is good to 107@5800
All that on a teeny 340/360-type cam.
I would pump the Dcr up to 8.0 to 8.5, which is in the detonation zone for 87; but my secret weapon would be in the tune, or 91gas. I would probably have 360 size valves in closed chamber teener heads, Like Magnums,with not much more than bowl clean-up, and flat-top pistons.
With a 262/270/114 cam, in at 110, the ICA would be 61*, and so;
Zero deck, 5cc eyebrows,8.9cc gasket ,closed chamber heads at 60cc,totals 73.9cc. The 3.95 holes make 664.47cc, so the Scr will be;9.99. Let's go with that.Easy. With a 9.99Scr, and 61*ICA, And a total chamber volume of 73.9cc, the Dcr will be 8.14, and the Cranking pressure might be 163psi.Close enough.
BTW that 262 cam might be a 218@050. That size cam could get by with less TC than earlier mentioned. That's "get-by". If you want quick off the line, you will need more TC, like 2800 to 3200, Ima thinking.
But If your pistons are already installed, then you will have to go with whatever they measure, down in the hole.and if you don't have closed chamber heads, well then compression,will not be your teeners strong suit. Not to panic, a bigger TC will get the engine past the soft spot real quick.
Back to the cam question;I still,DK
I put the above combo into a 71Demon back in the 70s. It was killer with a 340 cam,headers,LD340, and small 4bbl.I never opened the engine other than to pop in the 340 cam.....4.10s and 2800,will wake anything up!That's a starter gear of 10.05.
I ran a LC teener,with a stone stock long-block,and with a 10.97 starter gear, in my 68Barracuda; for 4 winters. Nothing but; headers, a factory iron intake, and a small TQ. It was TNT!
That theoretical cam above with 262/272/114, has only 39* overlap, so pretty tame. The exhaust doesn't close until74* ABDC, so there's plenty of energy still in the exhaust, to make nice popping noises.Put rectangular exhaust tips on it, and it might sound like a 340. Put the biggest pipes on it you dare, at least until the muffs. I used TTIs and dual 3 inchers all the way to the rear turn downs. Man that teener pulled.
Short of Supercharging, there is nothing that you can do to your teener that will be as effective as gears and a big TC. NoThing. 4.10s offer 50% more torque multiplication than 2.76s.. 50PerCent! That will feel like adding 159 cubic inches. Add to that a 2800TC, and that's another bunch of foot pounds. Your 64 will be launching like a BB;albeit a BB with stock equipment.Maybe it will feel like a stroker-BB;at least until it hits high gear.
This is how M/T Mustangs do it; A deep starter gear, well matched splits,and an O/D to cruise with.Sorry, with 4.10s; 60Mph will be around3250, so I guess you're staying local.
One more time: IDK what cam. I would wait until the Scr comes in.
