Well, I was about to rebuild my 273 and 904 when something happened. I bought another drive train. I had been keeping my eye on a rebuilt 318, 904 package that was popping up on craigslist for a few moths that was out of my budget and a little bit more performance than I was looking for. I had been so satisfied with my previous 273 heads and Cam combo from a recent top end rebuild (link) that I was pretty hell bent on keeping that build. But the priced drop, drastically, one day so I pulled the trigger. So here is the new project: 318 .30 over, 302 swirl port heads with bronze guide liners, competition valve job with 360ci valves installed, 1.88, 1.60. Hardened valve seats,C.C'd combustion chambers 63-65cc. Schneider Hyd cam 256-2H.450 lift, Edelbrock performer intake, MP valve covers and Air filter, Rebuilt Thermo quad 6410s with #1966 metering rods,, Milodon oil pan. Powder coated Intake, timing/water pump, air cleaner and valve covers. Rebuilt 904 trans with shift kit and new converter.
