why not run 1.6’s with it? it’s a lot of lift but if you port your heads down the road (or right now) it will make some very nice numbers.

and if you sacrifice 15-20 hp now, u might sacrifice 10 hp later… then another 10 hp with another mod. It all starts adding up.

if the tuning thing is an issue, a have a couple of buddies that have obdI f-buckets with a 306 cam in it. You can just peak at those tables if you need a nudge in the right direction.

it all boils down to this. everyone wants you to run the 306. I went through this phase with my car. I was thinking about just putting a hotcam or 305 in mine. I stick by the decision I made.
