Breathing new life into the 318 in the Scamp!
I'm not so sure about this cam. Seems that you were building a pretty mild motor,and that cam is over .500 lift. I would stay under .500 lift.
Did you call Hughes and give them all your cars specs ?
Or just pick that cam ?
You dont want to over cam the thing.
It's around .500 (491/522), but that's on a 1.6 rocker. On a 1.5 it's down at .461"/.489"
It's also a quick open/ close cut, so no duration, swamping overlap, etc. It won't even act as harsh as a .430"/ .444" cam, because the duration on those 340 cams is up at 268/276. That's a stick that will allow for high RPM/stall, tall gears, etc. The combination of slightly higher lift, still coming in shy of .500" and quick ramp on this cam is going to get the valves open and shut sooner. That caps the RPM up high, but delivers torque in the low RPM range.
Basically, the short duration trims the air that it draws into a narrower time window and opens the window all the way, all at once to increase the speed of the air, which is exactly what I'm already trying to do with the rest of this combo.
I have the lifters and springs that go with this cam, from Hughes, new in the box. I spoke with Hughes a while ago about this camshaft and purchased it, set it aside for a 360, but after thinking about how the upper half of this engine is going to want to run, and after some careful thought about how I may need to replace the cam in the car if I have a sticking lifter and after looking at the possabilities, I looked at this model again, online, and I think this stick will just make the goal of a high velocity flow system happen.
