different 318 question

I agree with the 262 comment above
your valve springs my be tired
the 256 cam mentioned above closes the intake about 55 AFTER BOTTOM DEAD CENTER ABDC
the Dual energy has a long exhaust (where does this help?) and 59 ABDC less dynamic compression for a low compression motor
but why look at multipurposed chevy cams
I posted this in another thread 440 rebuild
The Voodoo closes the intake at the same place as the 256 comp but has shorter intake duration and more lift than either comp mentioned, more even than comp 268H
you have to go to the comp XE 262 to get that much lift but it is a much bigger cam
Not pushing Lunati but here it makes sense or the Hughes there may be price differences- let us know
