I just got another 85. Not sure if this is a roller block or not? It has been punched 030 and has an e-cam, but I beleive it has otherwise stock internals. I plan on getting a set of 165 afrs and 1.7 rr or maybe 1.6s with enough cam? Only minor mods to motor is edel 1406, perf intake and msd. What will be a good lopey cam that will make me some good power up to ~5500, 6000 max. I am more after a sick idle and alot of low end grunt as this will be mainly a show car/weekend cruiser. Not sure exactly what pistons are in it, but I have the motor out now and will check. What comp ratio are stock 85 pistons? and with the afrs I should still be able to run on 93 pump gas correct?.
