Upgraded 360 Cam?
probably a pair of Edelbrock RPM heads within the next year. I currently have a dual plane intake, headers, 8.75 rear with 355's. I'm running a stock torque converter?
End goal is just to add some more low-end torque to the car and help the engine come alive. Not looking to go crazy with power, but make it a fun street/strip cruiser.
With the Eddies you can push the cylinder pressure to well past 180 psi.
That means you can probably run the stock 252 cam, stock convertor, and ANY rear gear you want.
So slam some KB107s on her, at whatever deck height, run a high-quality.028 gasket, bolt on the Eddies and go ripchit.
The 252*cam might make peak power at about 4600, but the Eddies will carry the power another 1000rpm.
With 3.55s; , 5600 is 46 in First/79 in Second /114 in Third; and 60 in Second is ~4200; so why stick a 6000 rpm cam into her? I mean you could with the ~10.7 Scr that the KB107/Eddies combo will get you; but why would you. it will not change your zero to 60 ET even one iota, unless you cure the traction issues. The 252 cam will spin the street tires at WOT, all the way thru First gear...... at least.
The absolute biggest cam I would cringe at is
[email protected], which is about a 276 advertised.
The biggest I would run is about
[email protected], which is about 268 advertised.
According to your stated parameters it would be a
[email protected] with 3.23 gears, which is about 260 advertised.
All of these to run with Eddies at about 10.7 Scr.
I would only replace the 252 if it was worn out.
But if I did replace it, I would try to find a cam with as much lift as the heads will work with, so that would be a custom cam.
Cruising with 3.55s, 65mph is about 3000. With 3.23s would be ~2700, 2.94s=2485
For this combo, headers are a good option but with overlaps this low, not a big deal; But forget the restrictive 360logs. Dual exhaust yes, but any old pipes will do. You also don't need a fancy fuel system nor even a CDI ignition system. So by buying the hi-compression alloy heads and installing the KB107s, you are pretty much done. Drive it for a few months or a summer, then decide on camming.
If you want to run the 2.94s, you might want to up yur stall. I like a 2800 for that gear; but if you decide to run the stock cam, I doubt you'll need the extra stall, so then, I'd just install the 2.94s and see how it goes.
3.55s are the right gear to blow the tires off at 32 mph on a 2-1 downshift.
BTW
Just bringing the pistons up to ~. 012 of the deck,Which is about where the KB107s land, and using the .028 gaskets with the stock iron heads, will bring your Scr up to ~9.6, and with the stock 252 cam your cylinder pressure might climb to 160, which will make a HUGE difference in how it currently runs.
If you install a bigger cam with a later closing intake, your bottom end is guaranteed to be softer.
If you want quick, easy and effective; this should do it. Heck you could even run it as a 2bbl and still get lotsa grins ........in first gear, anyway.
