1985 vett stock cam specs
looking for stock cam specs. lift and advertised duration. also duration @50
what cam are you using. the cam im looking at is 219/227 duration 112 LC lift 468/489. l |
FSM says:
Intake .2377 Exhaust .2820 Those are lobe lift, with 1.5 rockers that translates to Intake .410 Exhaust .423 Duration is not given. |
The info I found is 85 & 86 were the same. 202/206 @ .050", lift with 1.5 rocker is 403/415 and lobe separation 114.5. For the cam you are looking at, you may have problems with clearance. I have heard max lift on stock heads is around .480.

Hi I have the TPIS cam Torque Secrets : int/exh duration 221/230, lift .454 with 1.5 lifters
112 lobe separation. There is a slight lope on idle, but the cam is good gives a good pull. A stock engine will be slightly vercammed , but have good results . |
