Hey all, I’m looking at building the 289 in my 1966 mustang. I’m planning on using AFR 165 heads, with the upgraded 8605 spring package. I’m planning on using a hydraulic roller cam which I haven’t decided on yet. I’m going to pull the block and send it to a machine ship to freshen it up and balance the rotating assembly. I’ll put APR main bolts and rod bolts in the bottom as well. Along with this I’ll be installing a lightweight flywheel and full roller rocker arms. Right now I have a performer RPM intake and a edelbrock 550cfm carb. I’m planning on using the same intake and carb setup. Im unsure what to expect from this kind of a build, I would appreciate any insight or tips. I don’t plan on taking the motor over 7krpm often. Any recommendations for cam/lifters? Any ideas what hp/tq range this would get me? The car will mainly be a Sunday driver, with the occasional trip to the track. Thanks in advance!
