Hey guys,I building a 302 for my 66 and i wanted to put a comp cams (magnum 280H) 224 duration 512/512 cam but was worried about clearance, i would check it before runnig it but should it clear? I have silvo-lite flat top pistons with 66 small chamber heads(54cc) with stock valves. What i really is a comp cams extreme energy 268 duration (218 @.50?) which was 509/512 lift, OR possibly a extreme energy 274 cam (224 @ 50?) 519/523 lift. I want the etreme energy series if those numbers would clear. Thanks for the imput, this was asimular post of mine from th oterforum but with all the exact numbers, THanks ---Anthony ------------------

Any of the choices you have selected will clear stock style pistons with room to spare.  ------------------

Out of those cams listed, I like the biggest one.
Since it's a stick shift, I would go with something even bigger. About [email protected] duration and about .520 lift. Those tight chambered heads can handle more cam than you think. Then put in a 3.50-3.70 rear gear and you're good to go. ------------------

Thanks guys,The cam was the only thing holding me from finishing the motor, since i couldnt do the heads w/o the right springs i needed to see what i was gonna get. I most likly will get the 274 cam, i will consider a bigger one though, i have had other guys recomend a 280-290 duration cam as well. Thanks ---Anthony ------------------
