First off, I've kind of asked this question in other threads but wanted to try again to get anyone's experience actually building such a motor: 383, either massaged 906 or CNC'd Stealth heads, roller Lunati cam, 231/239 @ .50 535/550 lift, either 3.75 or 4.25 crank for 432 or 489 c.i., stock HP...

I've been trying to decide whether to go with HP manifolds or headers on my 383. I'm still deciding whether to stroke it or not, but I'm heavily leaning towards a mostly stock appearing car & motor. I google imaged "Roadrunner Motor" and was very surprised that most of the pics had manifolds...

I know I should pull & store my Roadrunner's numbers matching 383, but what I will be doing instead is building it to a 'safe' power level and just not abusing it unnecessarily; no burnout contests, limited track time, mostly cruising and 'feeling the power' from time to time. At what power...

Hi All, I have been waiting to rebuild my 70 Roadrunner for so long I've now decided to keep it 'mostly' stock, at least as far as keeping the original 383 engine, 727 trans and 8.75 rear goes. I've already spent some serious money on performance parts, many I'll likely not use now (can you say...

Not sure how many of these in 'as new' condition are out there. I don't have the box it came in, but as far as I can tell was never bolted to anything. Cool intake I was really looking forward to putting on a car at some point. $350 plus shipping. Thanks, Jim

Was going to rebuild this to have a numbers matching TQ on a 73 340, but project never happened. Nothing moves but besides being cruddy on the outside seems to be a rebuildable core. $25 plus shipping to anyone that wants it. Thanks, Jim

Some pitting as you can see, choke assembly moves but blade has been removed. Very clean set, would install as is unless you wanted to fix the choke. Had these for a project that never happened. $250 plus shipping. Thanks.

I already have this cam for a 383/432 build. I'm now considering a 383/489 build for 1) a stock 'looking' build with 906 heads, exhaust manifolds and DP4B intake or 2) CNC'd Stealth heads, headers, and probably a six pack setup. I'd like some decent lope but nothing too radical. Will this cam...

Hi All, I'm strongly considering a 'mostly' stock appearing rebuild of my 1970 Roadrunner (383, 727 Auto, 8.75 Rear) and have some questions for any of you that have taken that path. I already have a G/V overdrive. tight FTI 3000 stall converter for the trans and 4.10 gears for the rear. Not...

Hi All, I'm trying to piece together an original woodgrain dash so I only have to replace the old woodgrain with the repo decals. I need the radio faceplate with the 'round' knobs vs the vertical 'wheels' on both sides. Thanks, Jim

I've been gathering parts with the intention of stroking my 383, first for 489ci then stepped back to a 432ci stroker, but now I'm rethinking stroking it at all. It's mainly going to be built for local car shows with the occasional blast down the road, I might take it to the drag strip once or...

Hi All, So I was T-boned in an intersection while driving the Roadrunner. I was stopped waiting for traffic in front of me to move and a drunk driving a large Pontiac ran the red light on his side and ran straight into my passenger door. A buddy was sitting on that side and got knocked into...

Mopar P452993AE 'Purple' Cam & Lifters Kit, Very slight surface rust on the two outer lobes, should clean up fine, cam shipping box and small lifter boxes show their age but everything looks great otherwise. Cam specs are: Brand: Mopar Performance Manufacturer's Part Number: P4452993AE Part...

Super Nice NOS Small Block Chrome Valve Cover Set, box shows its age, valve covers look great. $300 Shipped

I bought this many years ago and at this point will not be getting another old car so putting it up for sale. In the decades I've followed Ebay I've only seen another one of these once and it was for a Roadrunner. Takes a standard size photo of your car just fine. Frame dimensions are 10.5" x...

I apologize in advance for this having covered before, I even remember reading it here and thought I had bookmarked both Websites, but can anyone send me the link for the two companies that reproduce Mopar fender tags? I remember there was one that folks thought might still do Mopars but when I...

Growing up I knew lots of shops that did all kinds of work on these cars but now days there's really only a few that actually rebuild anything preferring instead to put in crate or remanufactured drivetrain components. Like one promising 'do all' shop told me, "we mostly do crate engine swaps"...

Hi All, I'm about to get serious about restoring my 70 Roadrunner and have a question about what compression ratio I should shoot for. What I have so far: 440source CNC'd Stealth heads, Doug's 1 3/4" headers, new six pack setup either vacuum or full mechanical linkage carbs (or Mopar M1 dual...

So I've been putting off restoring my 70 Roadrunner for many years and now in my mid-60's my back has gone from an occasional issue to now being a total mess. I've got several things going on in my back at the same time that are contributing to it becoming a full disability. The Neurologist I...
