That cam is very radical so unless the engine is designed for a cam like that it will be a dog. Looks like a really old cam designed for cast iron heads. They used to run cams like that 40 years ago when heads didn't flow much.


Correct and thats the type of cam I ran in 1989>1991 in my low CR 6-pack 440 bottom end motor with ported (260cfm) 906's, this one>

We didn't degree it in back then but put it in straight up dot to dot. It ran real strong pulling to 7000, it had plenty of vtp with the 6pk pistons, thought it was quite mild actually. As for these old cam designs with modern heads being a dog, my mate ran a Dart with MCH ported Eddy heads (320cfm) on his 440 with 12.5:1 and it ran real good with the old DC. .590" 271@.050 sft making 600fwhp in at 103 with a 5000 stall.
