OK, several months ago I traded for an all alum. SBC.
Milodon block, 4.030 bore, early Dart heads ported by ODDY"s, BDS 8-71 blower 3.625 BRC crank with BBC snout, 8.5-1 comp. Crower rods, Venolia pistons, solid lifter flat tappet blower cam, (ODDY"s proprietary specs). It supposedly had only a couple of dyno pulls on it and had been sitting for a long time (15 yrs). (I got the build sheet from ODDY's.) I pulled the top end and cleaned everything up, looked at and miked the bores, checked valve spring pressures. etc. removed the valve guide seals, looked at a couple of bearings, then reassembled it. I also removed the two 750 Holleys and replaced them with a Bugcatcher and 80A-1 pump, #44 nozzles in the hat only. After installing this unit in my fed, I started it up and set the timing at about 36 degrees BTDC. It quickly became apparent that @ 10% over driven, this mouse would roar
. However I had observed that the rods, shown in the paperwork as "Crower" were probably Sportsmans. They are good to about 500-550 hp. Soooo, after bumping the throttle a couple of times, I sez to myself "self those rods ain't gonna cut it". Some quick calculations based on previous builds suggest hp. in the 850 range. Today i finally pulled the thing all the way down and next week I'll order rods and pistons and take the crank to my machinist for a re-balance.
