306 Dyno results

Just chassis dyno'd my Falcon. Motor was built with parts I had in my garage. 306 cid, TRW domed Pistons (fire slotted using advice from Psig and DanH) eagle rods, stock crank, Voodoo 276 flat hyd cam, Estreet heads 2.02 lightly blended and PAC racing springs. RPM air gap port matched with one inch open spacer and 700 DP Holley.

First pull was 302.76 RWH and 276.10 torque.

Second hit after new cap and rotor and some fine tuning was 316.95 and 294.65 tq.

Not bad for swap meet junk.

Re: 306 Dyno results

Well iirc the L2249N has a 9cc dome. Head has a 60cc chamber. Stock 302 stroke. 0 deck. I slotted the piston on an angle from the center of the spark plug towards the exhaust valve. Not sure how much I took out. (Wasn't too much) Pistons are .030 over.
