1974 plymouth valiant 360 LA 904trans.

I just bought it yesterday. The guy I got it from didn’t tell me what cam is in it. It’s a 4bbl. 3 speed auto. I haven’t tried anything yet because I don’t know where to start.

Try setting the initial timing at 17° BTDC and total timing at 35° at 2500 RPM....

If you want to have the distributor recurved for it, contact member @halifaxhops

He has a sun distributor machine and rebuilds distributors... He can curve it to what you want/need...
