fordracing 65 You have a problem, nothing that 20K willnot help fix. If you want a torque motor that will rip the tires of the rims, thats great. The only problem is having a 6,500 limit with the HP topping out at 6,500. Big bore short stroke motor is not going to give you both. You will have a large rpm range with the correct valve train and camshaft.
You have not said what oiling system you are looking at? The FI system is great, but which one has your eye? 8 stacks or 2,000 cfm throttlebody? With 427 cubes and 6,500rpm, a set of 48 mm throttle body will be at there flow limits. Camshaft is also very important for FI to work correctly. Something in the 112LSA to 114LSA min for your motor. Something in the .600- .650 lift is about max for a street driving motor to live and not have to replace valve springs every 10,000 miles or less.
What heads are you looking at? Clevor heads might be a good choice if you have the bottom of the ports filled in on the intake and chance of the exhaust to more of a "D" port with flat being on the bottom. Porting and matching the intake and heads will come into play. Joe Craine does one of the best jobs of matching each port on the intake to flow within 3-5 cfm of each port. This will help balance the flow to the motor. Just something to think about too. Rick l.
