First thanksto all for taking a look at this and the advice is priceless when directed at one's own issues. I say that because I read a lot and while invaluable doesn't always hit the point, and brings up the personal engine debate.
Bought the car built like it is with no history, runs fine as is, it is a 312 B7ME, maybe that BM part meant boat motor, some say maybe. It was born a six cylinder in Long Beach by the plate. It does have the later distributor but it will be on the shelf, the MSD 8383 with wires on the way from Jegs, $530.
Pete I don't really have a target improvement area, grew up with Fords two 57 300s at $25 each were my first cars, recapped tires, filtered oil, and gas at 25 cents a gallon. Lose a tranny and buy another car, thats how it was 1965 when I started driving. Car will be used as a cruiser, have other cars so don't care about mileage, not going to race anything just trying to stay ahead of the grim reaper. Looking to make it as powerful as possible without addressing the lower end.
Headers appear to be out for now based on value, and it has the late model exhaust. I thought I read an Eaton test on car headers that was a marked improvement for the passenger cars, still hope they're available now or coming soon.
Timing is being addressed, only had two timing marks on damper but ran well at the advance mark. Bought a tape to apply to damper and will have better look at where this unit will set up.
Question now is Mummert or no Mummert manifold, and I'm leaning toward the purchase, will be an improvement and fit well if I later decide to go futher.
Having a time with the site losing messages hope this one goes.
