351M sputters
My 77 f100 with a 351M idles fine. But accelerating it sputters and stalls. The truck also rumbles when you take your foot off the accelerator and slows pretty quick. Is this a timing problem? thanks

Check distributor timing and advance mechanisms. Check fuel delivery. Check both ignition modules (parts in distributor and on fender) and wiring. Most parts stores can test for free. Check timing chain slack.
