I would like to have seen one size bigger cam and a solid roller.That would make a lot more power

You know, sometimes you just hit a sweet spot and the OP has done just that with this combination. This little motor makes some very pretty hp and torque curves. Any of you guys who want a 327 that will pull away strongly from a stop and still haul the mail at the top, should emulate this combination. I used the flow numbers from the Stan Weiss site to run this Sim.....Dynamic Compression Ratio of this combo is 8.428:1.

RPM HP TORQUE
2000 138 363
2500 177 371
3000 226 395
3500 280 421
4000 331 433
4500 375 435
5000 407 428
5500 425 406
6000 415 364

Peak volumetric efficiency 92.7% @5000
Peak BMEP 198.7 lbs @4500
Maximize the combo by retarding the cam 4 degrees and pick up 9 hp and 4 ft/lbs of torque. 650 is just the right amount of carburetor.
Good job SSCamaro_510.

Man,those numbers are impressive! I'm not a drag racer by any means,I just wanted a small cube motor for semi-daily use to run on pump gas. Looks like I'll be going with the 3.42 gears instead. I can't wait 'til I'm back on the road in a couple Weeks. Thanks for that dyno Sim Techinspector.
