Your goals are acheivable with the correct parts, I've done it with 9.5 to 1 compression, 906 heads with 2.14 intake valves and 1.81 exhaust with mild porting and the Performer RPM intake with a 4781 850 Holley D.P. carb more than once up The cam needs to be big enough to flow a lot of air and have more than 6000 RPM at peak HP, which means as much lift as posssible up
The old school cams got left in the dust by progress work shruggyThe last one of thos pump gas motors I built and dyno had a Reed solid lifter flat tappet cam with 104 LSA and a lot of lift, I don't remeber the grind number now but look at Reeds selection on BB Mopar cams and go from there scope
Good luck, let us know your results thumbs
