Quote: you guys running 0 deck flat tops.. and the .560" or bigger cams..? what did you do for valve to piston clearence? did you have to fly cut the piston tops?
ive got a .030" over 360 0 deck kb flat tops with ported j-heads,offset intake rockers and no pushrod pinch. 280" intake runner volume.. going 11.20's with a Tiney .485" solid flat tappet. want to go .550" roller..but need to contemplate piston machining.. Did you guys find clearence necessary? id like to just do a cam/valve spring swap..with the motor in the car..
a cam should really pick my duster up.. cheapst
My motor is 5 out of the hole and the biggest cam i could run is 591/610 lift and that is with 1.6 rockers, with KB flat tops no cutting
Duration is more of a factor in VtoP clearance than lift. I have a roller that is 230* at .050 and .605 lift, KB107's .006 out of the hole, with over .120 clearance on both sides.
