I would like to make 1.4-1.5hp per cubic inch.(383)
Can it be done with this setup? I need to choose the rotating assemblies compression and cam.
Yes the STR will have a very strong top end and works beyond 7000rpm. It will not hold you back from making the power you want to make.
The cylinder heads/ headers and camshaft are going to be the determining factors.
You'll need a very good cylinder head to make this amount of power.
AFR195-210 ,Brodix T-1, IK200 ,Edelbrock Vic JR etc. 1-3/4" headers. 248++ duration cam 4000+ stall, big gear. If pump gas (94) use 10.5:1. max or less. If strictly race gas/track motor use as much cr as you can 13:1+ and run 110+octane racing fuel.
If you have 102 octane fuel readily available to you and will be running it all the time, I would build a 11.5-11.7:1 motor to use that fuel.
Build the motor to have proper .040" quench clearance.
