To be or not to be...

OK GURUS, HERE WE GO...
I WANT TO BUILD A QUICK "WINDING" MOTOR, MAXING OUT @ 62-6500 RPM I DONT WANT TO SPEND HUGE MONEY... AND I DONT WANT TO GO 140 MPH!

IM THINKING 377 (BIG BORE/SHORT STROKE)

AM BUILDING A 31 MODEL A ROD FOR STREET USE... TREMEC 5 SP, JAGUAR REAR W 3:70-ISH RATIO, 32INCH TALL CHEATER SLICKS.

THE WHOLE RIG SHOULD WEIGH LESS THAN 2000 #

NOW HERES THE KICKER, THE CAR CAME W A 671 ROOTS BLOWER AND 2 FOURS. SO IM PRESUMING THAT WILL MAKE UP FOR ANY LOW END TORQUE PROBLEMS.

I HAVENT BOUGHT HEADS YET BUT HAVE A NICE COMP ROLLER CAM THAT LIVES @ 2000-6500 RPM...

AM THINKING SOME SEMI MILD ALUM HEADS THAT WILL FLOW @ THESE RPM RANGES.

DO YA SEE ANY HOLES IN MY PLAN SO FAR??

build a 391 and it will rev quick.
How do you know what RPM the cam will rev?

You need to stop this foolishness of thinking that a short stroke motor will rev quicker and get to the lights sooner.....cubic inches RULE. Period. This combination of parts will make a 406 motor with a 7.8:1 SCR so you can push some boost into the motor and destroy your drivetrain.

cam specs for what engine? the box should have more info?
sorry,392= 4.155x3.62 stroke.6500 rpm is not much. 350 cranks are easy to come by.4.155 lets the heads breathe.
heads flowing 290 CFM will get you to 6500 RPM
NOW: choose the cam
