Default Alan you have left out some info

Alan P. Alan building a 302-331 windsor motor to make 425-450 hp is not a problem. 8,000 rpm is. What gearing and what trans are you going to run? 4 speed, 5 speed? What size tires? How crazy are you looking? Westlake Gurney headed motor? How do you define pump gas?? 91-93 octane? or 100 unleaded fuel? A set of Boss 302 heads with a single plane 800 cfm with get you to 8,000 rpms. For an FI system and the RPM you are looking at, Moldec. It's faster than Fast, I am not a big fan of Accel or some of the others. A 347 motor will give you more power and need less rpms to do the same. I think you already know that different tracks need different gearing. As far as parts for your motor, Callies crank, Crower, LAE crank,or Velasco with all the lightening work and coatings done to the crank. Carillo rods. Any good piston with both side and top coatings. Solid roller camshaft with oversized rollers. The oiling system will need some SPECIAL work. Possibly a spray bar for each head on the rockers, like Nascar. With out the intake you are looking at a 15-17K motor. Why not look into a busch motor from nascar. 355cid, 650+HP all the best parts, just change the pistons to less compression. High HP motor have a short life, large torque motors can chase high HP motors all day and pass them coming out of turns, you are only going to get caught on a long straight. Maybe a change in your driving style needs to be re thought? I am not a pro racer or builder but have found that a great handling car and smooth driver will beat a higher hp car 8 out of 10 times on a normal size track without 4000ft long stretches. IMO.
