Bogged down While In Gear And Sputtered During Acceleration

Who are you calling retarded!

Belay my last I meant BTDC..........

3 Days ago I installed a double timing chain set and set TDC with a Piston stop and the balancer matched up so I'm 99% positive the timing marks are correct.

Here's the cam info and thanks for the responses.

I wondered if it was just a typo. That's a pretty fair size cam for a 273 and will like a lot of initial timing to run it's best. The only problem is when you crank the timing up you crank up the total timing also so you have to limit it somehow, usually by welding up the advance slots. I didn't see where you said you put a timing set in it.

Just thought of one more thing. Are you still running vacuum advance? If so apply vacuum to the vacuum advance and recheck the reluctor gap. I've ran into a couple factory distributors that the gap closed up quite a bit when the vacuum advance came in causing it to run rough. A gap between .005 and .012 generally works ok so if it is closing up when the vacuum advance is pulled in set it then and recheck it after you unhook the vac adv to make sure it isn't real loose.
