    RPM varies wildly small block

    I rebuilt this engine in '99 and put the rockers that were on it then back on. I proceeded to drive it everywhere at 120mph after that and didn't do them any favors. I was looooong overdue for a new set, it turns out. As far as did this improve the idle, it did to an extent but you're spot on...

    RPM varies wildly small block

    Yes! I posted a quick follow up to stay online for the ages. Everything I did yielded incremental improvement. The ignition box and carb were the biggest.

    RPM varies wildly small block

    Hi All, It's been about 9-10 months from my original post. In case anyone is looking at this thread for conclusions. YES, I did get it sorted out and have a perfect idle. I'm not quite daily driving my car but I drive it quite a bit now. I did not have burned valves or any type of cylinder...

    RPM varies wildly small block

    It's been a few months and I finally got back into this thing. Who had their money on worn out valve train AND bad lifter AND fuel pressure issues AND defective cap and/or rotor? Turns out it takes more than one problem to have the RPM wander up and down 450 RPM at idle. I'm very close to...

    Hi Kurt, VERY cool RR! You don't want anything that came off of this car... trust me. Plus I'm putting it all back on. It only works because I'm building a disgustingly awesome ratrod. Lol

    Very cool chart! I'll see what I get once the new rocker assemblies come in.

    RPM varies wildly small block

    Will do on the new rocker shafts. I own a vacuum gauge but haven't relied on it much. I'll be sure to read up and the chart Mick56 posted is going to help get me started. I wish I had a known-good carburetor to throw on there for diagnostics. I may go back into mine to clean it up (again) and...

    RPM varies wildly small block

    Thank you for these suggestions, they're a GREAT set of leads. Truth is I've owned this car for so long these are my own mechanical failures coming back to haunt me. As kid in my teens & early 20s on the weekends I would run this thing hard and put it away wet. And then drive it to work and...

    RPM varies wildly small block

    This might be related. Have new rocker assemblies on the way. The really loose one was severely elongated, a few of the others aren’t great either.

    You have a rebuild on your hands but with it you have freedom. My 68 was in about this shape when I hauled it home. You can restore it to factory or build it triple black. Tasteful small block or a big block with a blower sticking out of the hood. The possibilities are endless and no matter what...

    RPM varies wildly small block

    It's a mopar drop in electronic distributor kit. I did recently figure out I've been driving around at 35 degrees of initial timing, and the car's always had a miss to it. This entire event has taken place at idle in park. I can hear the cyclical miss at higher RPM though. The plugs all came out...

    RPM varies wildly small block

    I did play with the timing but it was in an effort to resolve a miss and high idle. Apparently I've been driving this thing around at 35 degrees of initial timing for a while! I'll continue to work the timing / idle mixture.

    I've actually got the advance disconnected, I'm experiencing this crazy RPM bounce at idle with the advance port plugged.

    RPM varies wildly small block

    Hi, I’ve got a strange one on my hands... my 360 is climbing and dropping by as much as 400 RPM at idle. I’m curious if anyone has ever seen anything like this before. 360, 30 over. Street/mild purple cam. 16 degrees initial timing (approximate, it jumps around with the unstable idle)...

    Does a 69 4 door rear seat fit a 68 2 door Coronet?

    Naturally the monkeys working the scrap yard managed to set the upper seat frame on fire while cutting the hinges out with a torch... I passed.

    Does a 69 4 door rear seat fit a 68 2 door Coronet?

    Thanks guys! It would have been convenient if they fit but I didn’t want to guess and be stuck with the wrong seats. I’ll settle for two buckets up front and revisit this once I have it on the road.

    Does a 69 4 door rear seat fit a 68 2 door Coronet?

    Hi All, Sorry if this one’s been covered before, I really did dig through the forum posts before asking! I’m going to the junkyard not far from me, they recently got a 69 Coronet 4 door in. The car still has the main parts I’m looking for (trunk hardware) but in case I get lucky and it still...

    Thanks - I actually found some in a junkyard not far from me, heading to get them Monday. If they don’t work out I’ll check back in.

    Do you still have the hinges that mount to the wheel wells for the trunk?

    FOR SALE 68 2dr coronet part out

    I just re-read my original post, I seem to have mixed up hood and trunk? I'm after the trunk hinge mounting parts. I'll be you figured that out though!
