Car: 87' GTA Trans-Am Engine: 355 TPI Transmission: Built 700R-4 Axle/Gears: 3.27 9-Bolt | Less Vacuum/ PROM problems With 1.6 Roller Rocker Arms???
Alright,
I just got off the phone with my mechanic who set up my heads about installing a set of 1.6 roller rocker arms.
He says I should have no problem with clearance, since I've already got a .500 / .510 lift cam in there now.
The only concerns that he mentioned were that the engine would be pulling less vacuum at idle and could cause drivability issues and mess with the PROM I had burned for the car.
I don't want issues with my computer or problems at idle.
Will 1.6 roller rockers cause the problems mentioned? My car already idles at about 900 rpm most of the time anyway. | | |
