hello, i would like to know what gives the choppy
missing sound in a camshaft.
Is it overlap caused by tight lsa? or high duration?
I have a 4 bolt 350, with vortec heads and the rpm intake,
and probably getting a 650 cfm carb.
I like highway driving, but top speed isnt an issue.
car has 5 speeds and 3.45 gears.

thx for any help

 

anybody ?
how about xtreme energy 262h, hyd
218\224, 0.462/0.469, 110

I think the 268h would be too much..

 

Its the overlap.

 

I got the 268 in mine runs sweet but not that much of a choppy idle but its noticalbe. If your building it to drive alot go with the smaller cam.
