We know that UDHarold designed the HE268 and others in that time frame Before Ultradine and Lunati
I have no idea who did the dual pattern stuff with the ultra long exhaust lobe- squeeze it down to a 107 and you would have a -whatever you call those fool things Hughes and others sell- real special applications or they do not work right
crackedback maybe soo- more gear would have helped as would a xe274HL and more gears (if he likes the rpm range of a 274) I'd have to look at his 60 ft times
lead69 what was you mph?

The poorer flowing the heads the bigger the cam you need to make peak power (no street idle gas mileage bs). A 360 with 318 heads is a fat man sucking through a straw and it needs all the help it can get to breath. I believe the reason mp cams were so big on duration and not lift was the factory heads flowed like crap at moderate lift so add some extra duration=more cylinder filling time. That 360 ran like a healthy big block 383 with a 280 cam, it would roast the tires at 30 mph and was a beast from 2k-5k, shifted at 5,400 ran shitty times due to street tires but 103-105 mph. It did alot better than anyone would have believed including me lol.
