    My Dart is exactly what you described wanting.... except I run a procharger with a 408. It runs 10.00s at the strip (has been 9.95) and I drove over 1200 miles on dragweek 2021 in 4 days. I only run 10lbs of boost. That is at the tract and on the drive. As has been said.... on the long drive...

    408 stroker 8-71 blower e85...teach me

    I agree that the procharger probably makes more sense than the roots style blower but if that's what you want, go for it. I have no experience with a roots style blower but I think I'll go down that road someday on a different build. My 408 is 9.0:1 compression and I run 10 lbs of boost with...

    68 Twin Turbo Dart

    I'm tired of breaking torqueflites and got a guy close to me that can build a bullet proof glide. I've been through 3 904s and a 727. All had good parts. Currently a Cope built 904 that has lasted the longest but starting to give me trouble.

    68 Twin Turbo Dart

    Yeah crank snout was also a thought of mine. We'll see, it doesn't take me long to blow stuff up so I'm sure engine and trans will come out at some point. I might switch to a power glide when this 904 goes.

    68 Twin Turbo Dart

    That ritter block is what I need to be able to turn my boost up. I think I could make 1,000 HP with my current parts but too chicken to turn the boost up on the stock block. Maybe after drag week this year I'll go ahead and install the 8.50 certified cage and start working towards going...

    My light weight aluminum bumper brackets came with light weight carriage bolts.

    71 Dart / 5.9 Magnum / Procharger

    Just realized I haven't updated this thread in forever. I think the dart combo is finally lined out and happy. I've only been doing 1/8th mile racing but the dart has now been 6.29 @108 in the 1/8th. That was with a 1.33 60 ft. I haven't had it to a 1/4 mile track but that should be in the...

    71 Dart / 5.9 Magnum / Procharger

    Yes, sir, that was part of the weight loss program in 2020. Both front and back bumpers are fiberglass but covered in chrome vinyl

    10 lbs but only 20 degrees total timing.

    71 Dart / 5.9 Magnum / Procharger

    Last night went good. New Brakes felt good and held the car good on the line lock during the burnout. Only made one pass and it went 6.60 @ 105 on a very conservative tune. After that pass I realized I haven't run the valve lash since break in so I need to do that before I make another pass...

    71 Dart / 5.9 Magnum / Procharger

    I think we went .024 and .026 but I'll have to look to be sure. Last go round was .022 and .024. Although when we took it apart it looked like pure detonation... it didn't look like the rings had butted together to explode that part of the piston.

    71 Dart / 5.9 Magnum / Procharger

    Here is a current picture. Finally converted to disk brakes up front this winter which was part of my weight savings. The HUB on the wildwood Brakes was too big for my front steel wheels so I switched to these American racing rims (More weight savings). I don't mind the new look but someday...

    71 Dart / 5.9 Magnum / Procharger

    Hey guys, it's been a while since I've updated on here. The car was down most of the winter due to me being very busy and waiting on the machine shop. Anyway, we are now freshened up with new pistons rings and bearings. I did take almost 150lbs of weight out of the car over the winter...

    Ebay GT45 + 5.9 Magnum + E85 blow thru

    Let me know how you like the MPI Megasquirt. I may get rid of the blow through carb next year and go MPI.

    Ebay GT45 + 5.9 Magnum + E85 blow thru

    Which Eddy MPI intake did you go with? Is it factory or did someone modify it? Just curious because I'd like to go MPI someday. I'm currently running an EDDY Victor which they don't make for MPI. They make a Super Victor in MPI but I don't think my combo would like it.

    Tranny troubles

    Another vote for John at CRT. He built me a 904 that's holding up to my 700 horsepower so you know he can sell you parts to make a 727 live!

    71 Dart / 5.9 Magnum / Procharger

    Pulled the engine. When I got the heads off 7 out of 8 pistons were hurt. Turns out 27 degrees of timing and pump gas was causing detonation during drag week. Once I realized I started adding race gas and backing off the timing but it must have been too late. I think the engine was finally...

    High compression and turbo

    Never mind on the E85 then. As mentioned the pump E85 is a crap shoot and it would be a nightmare getting your tune right. Only way I'd go E85 is with fuel injection and a flex fuel sensor. Just be very very careful with the tune and that compression. I am running 9:1 with 10 lbs of...

    High compression and turbo

    I was also wondering about E85. Is this going to be blow through carb or fuel injected?

    71 Dart / 5.9 Magnum / Procharger

    Okay guys, the last pass I made down in Alabama the car slowed down a bit. I had hot lapped it so I didn't think much of it. The Next day when I was unloading the car off the trailer it was missing. I pulled the plugs and the #5 cylinder's spark plug looked like the picture below. Ground...

    Twin turbo duster update

    Cool, I looked at your thread. You said all mopar so you running a Dana 60? What's the rear suspension set up? Just curious, my best 60 ft so far is 1.38.

    Twin turbo duster update

    Wow that engine build is very similar to mine. I'm running a procharger though. I didn't go with an aftermarket block and probably should have that way I could turn up the boost someday. I'm only running 10 lbs. Roughly how much boost did you make on the 8.77 pass?

    The event was a ton of fun. Weather could have been better but still a blast. You should try to make it next year. He already announced it's going to be 10/10/2020.

    71 Dart / 5.9 Magnum / Procharger

    Okay guys, finally getting the tune dialed in on the Dart. Went down to a MoparVSBrandXshowdown in Alabama. Went 6.42 @ 106 MPH in the 1/8th mile. Wish it would have been a 1/4 mile track because that would have been a VERY low 10 second run. Best of all I beat a big block, big tire...

    Great times! Have you posted the engine and turbo specs somewhere? I'd love to know more about the combo. What transmission?

    71 Dart / 5.9 Magnum / Procharger

    It was good to meet you Dusted. Thanks for posting a few pics. Best pass all week was 10.43 @ 119. I chased ignition troubles all week that ended up being the MSD Box. Once I got that replace I lost 2nd gear. Last day, it went 10.45 @ 129 shifting directly from 1st to 3rd. Transmission...

    71 Dart / 5.9 Magnum / Procharger

    Went to Bowling Green and ran 10.65 @ 128 MPH. This was spinning off the line and belt slipping so only 6 lbs of boost. It launched very hard (wheels up) then spun about 10-15 feet out. I think the track was slick because I saw tons of cars hook then spin. Stole my wife's oven pan for a...

    71 Dart / 5.9 Magnum / Procharger

    Hell yeah, look for the Dart and come say hello. Concerning the hole, I just didn't know about driving through hard rain (or it sitting in a hotel parking lot) and getting a bunch of water in my distributor and other electronics. The hood scoop was mostly going to just keep water out of the...
