He meant a tooth on the distributor / oil pump drive gear. Initial timing setup on a fresh motor is just to get it started, timing needs adjustment during breakin - it could easily be off a tooth.

Thank-you! I stand corrected, as there is a 'SLOT' at the end of the distributor shaft, that engages the oil pump. The distributor could be 180 degree's out-of-sync, but not sure the car would start...

Someone asked for the specs- post them up
how far down the hole are the pistons forged or cast
which heads
what's the quench
otherwise what's the real compression stillhigh compression stock or did the builder outsmart himself dropping the compression height our use rebuilder pistons???
which "purple cam"
lots of good suggestions
first thing is to pull a spark plug and bring the piston- you can use a bbq skewer to feel the piston come up to tdc then check the timing
you can then put a degree wheel on the crank and and a dial indicator on the intake retainer and check the timing- you might do a compression check first- it will tell you if you are way off

I had a 1964 Dodge 330 with a 383 and push button 727. It was a former Illinois State Police car. When my car began dropping in mph, finally to about 45 mph as you indicated, I changed the fuel filter and problem was solved. I wouldn't assume any errors on the part of the builder until you check the fuel system and then the ignition system.

Who, when working on rebuilding and reinstalling an engine, would slide a distributor back into an engine WITHOUT checking the initial timing setting? Just sayin'.

Hi Spence. I just saw your post. We had the exact problem with a fresh 440 stroker motor rebuilt at a local shop. I thought it was definitely the cam... so I pulled it apart & it was in wrong... the shop put it in and timed it with the wrong mark on the crank gear. I reset it and now it runs like it should. Ours had dish pistons so none of the valves hit. If yours doesn't it could have possible valve damage. I would reset your timing and then do a compression test before you put the front end back together. Brad
