89 360

I would just do a good performance rebuild. ,030 over, KB hypers, stock crank and resized rods w/ARP bolts. I wouldnt bother with the windage tray, it wasnt desgned for 3.58 stroke, and it's much less effective because of it. For heads, the 308s are fine. I'd install the 2.202s, to put the seats out further, and the longer stroke doesnt loose low end like a 318/340 will. I'd also clean up the bowls, and gasket match them. For a cam, that '89 has the hyd roller in it..Replace it, or have it reground for performance, and run it. Another thought would be Magnum heads, with the 1.6 ratio rockers, and great chamber/ports... Prob can get it done very nicely, for around $3600.
