This is from CarCraft Magazine. The engine is the Ford Racing 5.0 (same as the one in my 66), rated at 345HP with Ford Explorer EFI. Puts out a lot more with a decent intake and carb.

The 345hp 302 crate engine is available in two configurations: PN M-6007-XB3 comes with a manual trans flywheel and the B303 roller cam; PN M-6007-XE3 has the E303 cam. Otherwise, the long-blocks are the same.


FRPP GT-40X aluminum with 64cc chambers and 1.94/1.54-inch valves; according to FRPP, the 178cc intake ports flow about 249 cfm at 0.550-inch lift (28 inches of water) and the 62cc exhaust ports flow 170 cfm at 0.500-inch lift


B303 (manual trans): 224/224 degrees duration at 0.050 lift, 0.480/0.480-inch lift, on a 112-degree LSA

E303 (automatic trans): 220/220 degrees duration at 0.050 lift; 0.498/0.498 lift, on a 110-degree LSA

Compression: 9.0:1 nominal

Pistons: Hypereutectic flat-top

Block: New production 5.0L roller-cam two-bolt block

To set a benchmark, we bolted on a FRPP high-rise dual-plane intake (PN M-9424-E302, which is basically an Edelbrock Performer RPM) and tested several out-of-the-box carburetors on it before settling on the best performer—a 625-cfm Road Demon, which made 370 hp at 6,000 rpm and 358 lb-ft at 4,100 with the stock jetting. The air/fuel ratio was perfect as delivered and the only change we made was to swap a lighter spring into the vacuum secondary pod to ensure the throttle bores opened fully during the dyno pull

Conventional wisdom has it that Tri-Y headers, like these for a ’60-’65 Ford Falcon from Dearborn Classics, are designed for low-end torque and easier fitment in tight engine bays at the expense of top-end horsepower. Well, guess what? With 15/8-inch primaries forking into 21/2-inch collectors, the Tri-Ys made more peak and average horsepower and torque than the four-into-one long-tube headers, and actually exhibited a slight dip at the low-end. Combined with the Road Demon carb and dual-plane intake, these produced the best power of any combination we tested: 376 hp at 6,000 rpm and 361 lb-ft of torque at 4,100.

You should be in the ballpark of 350

Here is the AFR link : and here is the dyno sheet. This is taken right from the AFR catalogue. Look at the lower RPM power numbers. Looks real streetable to me considering the peak power level is @ 6100 RPM. Great torque numbers @ 2500 RPM.

That AFR dyno test is nearly a 'clone' of my 306 EXCEPT I'm useing TFS twisted heads with a little bit of porting to them.
My HP was higher, rather not say what it was but I'm using a carb also.......
