You don't need a cam.
You need an A500HD overdrive with a higher stall convertor;
And maybe a lil more rear gear, but 3.7s with a 2.74 low gear is pretty close for having; "just a lil fun".
You can thank me later.
If you up-cam that 8/1 slug with no other changes, then
you are still gonna need a convertor, and
may still need more first gear, and
Second gear will be all wrong until 3500rpm, which in your case could be close to 50 mph.
Since yur gonna need these things anyway, you might as well start with that A500, and a stall depending on the chosen rear gear.
---------------------------------------
I guarantee you will never be sorry about the od trans, nor say, a 2800TC, nor say 4.10s plus/minus 5%.
But I can guarantee you, that a bigger cam with no other changes, is LIKELY to be disappointing. As soon as your engine shows a pressure loss, then at take-off, it will feel like a smaller engine; and this feeling will persist until nearing the torque-peak, but will be most missed below 3000>3500 rpm. In your case, with an A998(2.45low) and 225/75/15 (88")tires this is likely to be up close to 30 mph.
Is that what you call "having a lil fun?"
I didn't think so.
You need AT LEAST a 2800 in that car with a 360. Over a 2000/2200 stall, that is already a super improvement and cannot be matched by any other bolt-on, save for supercharging. I'm gonna guess at 2800 versus 2200, the power difference even with the stock cam, is around 30/35 hp. You'll have to up-cam at least two sizes to match that power increase at the power-peak, never mind off the starting line at 2200. Do you want that power increase off the line? sure you do, everybody does.
And we haven't even talked about 3.7x2.45= 9.065 versus 4.3 x 2.74= 11.78, an increase of 30 friggen percent. No street cam in any 8/1 NA360 can touch that; that is tire-frying territory.
If, after you have installed this A500/2800/4.30s, you still think you need a cam, then your idea of having "just a lil fun" and mine, are way out of alignment.
