Ignition timing 3.5 with cam

Post by Outcast » Sat Jun 08, 2019 5:31 am

Does anyone know what the recommended ignition timing is for a Piper 270 cam fitted to a 3.5 engine, fitted with a 390 Holley, headers and MSD ignition?
Thanks in advance

I recently had mine rebuilt engine with the same cam set up on a dyno at 15 BTDC at 1000rpm tickover. And 32 BTDC at 4000rpm. Both without vacuum attached. Power at engine 201 BHP. This should give you a good start but without a dyno setup it will be difficult to know if optimum! Good luck!
