    Our B Bodies are just valuable!

    Monaco66coupe: I was street racing against a 396 Elcamino back in 1977 one night. I had a stock 1970 stock Road Runner with 383, automatic. At about 1/2 block I'm passing the Elcamino about 1/2 car length ahead of him when a bright flash blew his hood open. I turned around and came back. He blew...

    Removed girdle, reinstalled windage tray and oil pan. Reused Kieth Black oil pan gaskets. No leak, dry as a bone! NOTE: the girdle may be fine as is in a non-modified engine? My oil passeges were enlarged to the crankshaft and rocker oil feed. High volume pump. Full fillet Callies crankshaft...

    MOPARcrazy that is a great looking cross bolt kit, I may do that. Looks better than others I have seen. I'm sure California has a good variety of MOPAR savvy machine shops to work with. Here in Alaska I have only a few. They work on 99.9% Chevy & Fords. Boring, honing, clearanceing and other...

    Lewtot184: I totally agree. If this block fails (I doupt it will) but if it does I'll go with an after market RB or Hemi with cross bolted mains. Like I said in my original post, I have never had a problem with a big block strenghth. Here I go with an opinion that Im sure will be debated: Big...

    billet rear main seal for big block

    Thank you cr8crshr, I have been looking all over for these seals! All I could find was the black hard as a rock (stiff) felpro seals. Changed them 4 times now, they all leak like crazy - hate them. I used to get these red viton seals years ago from Direct Connection. Nice soft, pliable, never...

    Reward for fender tag and build sheet

    RM23N0G104679, 1970 Road Runner. The car is in Alaska now, but was bought from Indiana about 15 years ago. Only lead I have is, possibly who ever did the body work in Indiana: right front fender may have took the fender tag. Who ever reupholstered the seats may have took the build sheet. Or the...

    Differential question

    I agree with most the posts here. Keep it simple, its sounds like you need to change out the diff lube with new oil. Make sure to add put in sure grip additive "hypoid" or the clutch pack wont slip. They will wearout real quick. Your tires may chirp around the cornres too. By the way your tires...

    Pilot bearing, crankshaft

    I am reading that people are saying the torque converter nose goes into the pilot hole of the crank shaft? Wow this is new to me. I have changed automatic 69 RR to manual, and 70RR manual to automatic and never saw anything like that. I dont claim to know everything but the torque converter does...

    Pilot bearing, crankshaft

    I think I would check a couple things before getting a new converter. Is the converter all the way in the transmission: three clicks? Is the flex plate the correct direction hole 180 from drain? Is it the correct diameter, 130 ring gear teeth for a 383? Im not sure if this next thought would...

    70 Roadrunner air grabber hood slam

    Thanks shovelluv, that is eactly what I was wanting to know! Back in the early seventies when I owned my first 70 roadrunner, a friend at the Plymouth dealership told me there was a hood brace available for airgrabber hoods. He was a mechanic, and said he installed several to help with the extra...

    70 Roadrunner air grabber hood slam

    After years of slamming the air grabber hood by previous owners. The hood skin has seperated from the hood frame. The skin puffs up at high speed and has cracked at the rear hood bulge near the call out insert. My question is: what is the rubber like caulk that Plymouth used to seal the hood...

    Copper fuel line

    I did find a reason not to use aluminum. I only post this reply because I have read quite a few people on the web stating use aluminum. I tryed to copy and paste it here but Im not familiar enouph with is site yet to be able to do that. In the handling book of E85 fuel it states materials to use...

    Copper fuel line

    Refrigeration tech is a good carreer. Installing new or repairing is great, servicing sucks! Some systems are worse than being on the inside of a septic tank. One good thing is you learn real quick which restaurants to stay away from!

    Copper fuel line

    My question is: has any one used copper tubing for fuel line on a carburated car? I think I searched the forums properly, can find no discussion for this question. I have read other google search site forums and there seem to be a thousand self proclaimed expert answers. Most say it is to soft...

    1970 bucket reupholsery using 1973 frame. Are the frames same size?

    Photon440, thanks for directing me to that thread. It was very interesting. Most was in reference to 71 and newer bucket seats. But there was one or two remarks of 1970 seats. From what I gather is 1970 is the same as all the newer buckets, other than the plastic back cover because of the hinge...

    1970 bucket reupholsery using 1973 frame. Are the frames same size?

    I have 1973 bucket seats in my shop. I have a 1970 Roadrunner. I want to reupholster the 1973 seats with 1970 seat foam, Upholstery and backs. I know the plastic backs are different. I dont know what the difference is. I have been reading for years that 1970 was a one year bucket seat year. So...
