I'm sure some of you will recall the HitMaster launch control system I had installed on my Roadrunner. It requires a hydraulic throwout bearing to operate, and a clutch and pressure plate that can handle slipping under significant power without scorching the friction material, in my case a...

9 years or so and she has been a good mill. 71 440 block, with 6bbl internals. Of all the crappy times for my 440 to "give up the ghost" 2023 Cruisin the Coast is pretty bad. Crazy thing is, I had absolutely NO warning. I just did an oil and filter change on my Roadrunner and my wife's GTO...

I have known for some time that the N²O timing retard and launch control RPM limiter (separate from the max RPM limiter) were in the works since I was just about to order the new smaller diameter billet aluminum distributor from Progression. I was literally calling to order one January of 2022...

Since I'm sending the entire package along to my builder and it's Saturday and I don't want to call Michael at B3 on a weekend, I am asking here. I see the holes in a couple of these valvetrain geometry correction spacers are different shapes. On one end of the zip tied stack the hole is...

I'm asking because I was thinking about the challenge and the joy and sense of accomplishment just completing an event like that would bring me. I have had no time to do much of anything but work and work my wife wants me to do that needed doing, but a big part of that was a vacation house that...

I figured I'd start a build thread on my Bill Mitchell aluminum RB (big bore 4.50") block, and I may throw in some chassis and traction aids stuff along the way, along with the Nitrous Express 6bbl N²O system if and when that time comes. I am having it gapped for up to a 350HP shot. To kick it...

The explanation I got from Ed at Molnar is that the length of the stroke (4.5") affects the timing of the oiling. It may also have to do with the rod bearing as well. I was concerned when I was told that the oil passage in my Molnar crank is not "straight shot" like Chrysler uses. I don't know...

My not being a builder and mostly street driving my Roadrunner vs mostly or exclusively racing it, the topic of 2618 vs 4032 aluminum alloy (for pistons) came to my attention. My builder has ordered the rotating assembly for my 572 and he mentioned that the Diamond pistons (4.50 bore) were 2618...

Andy said he liked the 4.25 stroke. I can see quite a difference in piston speed between the two, but then again, I'm not likely to be wringing it's neck like a high compression, radically cammed 440 would. I figured I'd put the question out on the forum. I'm getting to the point of paying for...

I am interested in any story about 383 builds, from stock to "shadetree" performance builds (like my friend did in 1980, more to follow) to all out wringing the most power out of the factory 383 block possible. Back in 1979/80 I hooked up my best friend with a local cruiser. Being a Mopar guy...

I figured this forum section or Resto-Mod and Pro Touring would be the 2 most appropriate for this comment. I had Quick Performance build a 9" rear axle assembly for my wife's GTO. Pricing out rear axle assemblies with the well known players, Moser, Strange, etc and even with the step up options...

I may have to reconsider my plan to have a little "backup" just in case I need a fender length in the last part of the track, although I already have the Nitrous Express 2bbl spray plate, this offer from Holley and NOS...well, see for yourself!

I've had to be aware of oil out of the driver's side valve cover breather ever since I changed from the factory stock PCV and valve covers. I had that factory black breather that has some internal headroom height and "dual wall" design that only allowed vapor to exit via the vacuum hose + PCV...

Weather is nice compared to what we have had. Original date was pushed back to today. My buddy's LS2 centrifugal supercharged 2005 Vette is running 9.1X in the 1320. MOPAR is represented too, bigly! A number of "Hellcat cars" and a beautiful 9 second, factory block 426 Hemi, 70 Challenger...

"Friends" in quotes because some of you may just tolerate me :D Regardless, I really appreciate it, and if you would please take a quick look, I want to see if I'm missing anything that I should do now that would be a LOT harder or impossible or a LOT more expensive to do later. The things I'm...

So a few driveshaft manufacturer reps as well as individuals who make driveshafts, all reputable and referenced, have said for me to be assured that the critical RPM requirements won't be exceeded, my appx 50¼" chromoly steel driveshaft has to be 3½" diameter. Strange Engineering rep said 3"...

I was looking hard at Strange, because I saw a chromoly steel shaft at what I thought was a reasonable price. The driveshaft I have now is the one that came in my 70 Roadrunner, but I'm certain that it is NOT the original driveshaft, as I had to have it shortened slightly and rebalanced. My...

Please bear with me guys. I may never add nitrous to the stroker I'm finally taking action on to build. Yep, I sent the deposit on the BME aluminum block, so I know that isn't much $$ compared to the total cost, but every journey begins with the first step. I know I may struggle for a while to...

Man, I can see there's a LOT of people who are ready to get out, and go RACING! I'm loving it, even though I didn't bring the GTO or my Roadrunner. MOPAR representing! Dragster has a 1968 iron block, Cuda has a .030 over 440.

Please bear with me, I'm going into a lot of detail because I want you to know why I'm so determined to keep and use this intake, but I also really want the N96 setup on my 70 Roadrunner. Ok, some of ya'll said that you didn't think the old school Weiand P3690982 6bbl intake would fit, a guy on...
