Need help with a cam selection for swap

-I did the math on your combo, and get: 10.5cr. Thats 65+5++8.4+0(heads,eyebrows,gasket, and deck, and With 748swept.
Thats (748+78.4)/78.4 =10.48 cr

Heres the thing; most streetable cams in the 220* to 245* range will torque peak around 3400 to 4400 rpm, and peak power falls around 40% later, give or take a bit; so in the range of 4800 to 6100 So the power band is from the torque peak to the power peak , plus what ever over-run your tranny needs to stay on the pipe; generally 600 to 1000rpm. So to stay on the pipe with the small cam,and a close ratio 4 speed, you could be shifting out at around 5400, to come in at 4200. And to stay on the pipe with the larger cam and a wide ratio, you could be out-shifting at 7100 to come in at5100.
So what does that mean?
Well a strong running 318 with a short period cam can make more torque at 2500, than a long period cam in a 340, and maybe in a 360 as well,at that same rpm, and very possibly, several hundred rpm higher.
The FIRST point Im getting to is this; When a cam manufacturer throws out a power range number beginning at 2500 you might be tempted to think POWER when you should perhaps be thinking TORQUE.
Unless your pockets are deep;Power at the top almost always trades away torque at the bottom. And for street running, big torque at 2500/25mph with good traction, is a combination that is very hard to beat. This is 4.10s @1.92 second and 27" tires, with a stick car, and not too much different with your tranny/TC.
With 3.55s and a 2.66 low the POWER with the 292/509 doesnt hit til 43mph.With 4.30s and a 3.09low it hits at 30mph. But nobody cruises in 1st gear. So the second gear math puts the hit at 49mph with 4.30s(1.92 2nd). And this puts the engine at 2500/24.5mph. So that motor has to get from 25 mph to 49mph using TORQUE. You better have some there. The 292/509 does not.And most times the fooling around is done by 49mph anyhow because the car has probably been speeding for quite a bit, already.
So SECOND point is this; a streeter needs Torque at cruising speed.
I often think guys with street cars get carried away with the HP numbers.At under 50 mph the big numbers IMHO are over emphasized, at the expense of the much more useful, big torque numbers.If I live long enough, Ima gonna turbo a Teener. Reasonably big ft lbs, smooth delivery, and excellent MPGS, low maintenance, Drive it everywhere. I wish Ida had the money 15 years ago.But I digress.

Of course at the track, torque at 2500? who cares.
