[QUOTE="lakesnake1, post: 13516834, member: 136644"] Snake, Yes the car is def in cruise in condition. Has been repainted and is in really good shape - a belmish here and there. It is running rough at idle - especially cold. I did ingition wires to cure a mis it had but still running rough at idle. I checked the dwell with a meter and it said around 34 degrees which kind of freaked me out a little as the specs I have say 24 - 26. The points distributor has been changed to electonic - this is new to me - has black magnet (i think) that goes around the dist. shaft and a sensor where the points would noramlly be. Does the dwell reading indicate the sensor is perhaps bad/worn out, or is there an adjustment some how? Once i get that figured out I will reset the timming. But I keep seing different timing specs out there - most say 6 deg. BTDC and reccomend going to 8 deg. on todays gas. But then I also saw 6 deg was for manual transmission and the auto should be 12deg which I thought was a little radical of a change from manual to auto. Also what RPM should I time at? I read 600 RPMS somewhere and thought that was about right. Do you know of any good sources for the tune up specs? Seems the more I look the more diff answeres I get. Maybe I am getting mixed up with auto vs marine and older vs newer 351's. I think the wheels are Magnum - I will have to check out the size - haven't really looked. +1 on the SCCA C/P championship - that's cool - must have been a blast! What did/do you run in the autocross? I was thinking the same thing - 4bbl, headers and maybe cam and be done. But then I start thinking possible heads too but there is a budget, and at that point might as well rebuild the internals while its open..... Lake [/QUOTE]
