My Suburban died last night!

[skyhawk1]

Coming home from Beckley, WV last night the burb was missing a little (been missing for a few days). It just died while cruising along at about 60 mph. Smelled gas strong when I got it stopped beside the road (it's really hard to stop it when it's not running). Anyway, I thought it was carburator problem because I just installed a rebuilt Quadrajet from Advance about a week ago. So I called home and my sons girlfriend came to pick up my son and me up. We took the Edelbrock that I took off back up and put it on and still nothing. We decided it may be the coil so we went back home and took the coil off my 71 and tried that. Still would'nt hit. Anybody have a clue? Someone told me that my cam lobes may be totally worn off. The burb has the original 350 with 122K miles. It's been running great. Any help would be appreciated.
