New baby may have had something to do with this......... https://www.nascar.com/news-media/2024/05/28/stewart-haas-racing-to-close-operation-at-end-of-2024-season/

I think i'd just drive it and enjoy it. If you only have access to the 1/8th mile, you'll only be trapping in the low to mid 5's and that mph wont give a true hp number. I'm not familiar with your car, but it's capable of 130 plus in the qtr, and that may open up another can of worms with tech.

With peak tq around 5k it looks like you have enough cam to realize some decent gains.

Don't blame you for wanting a 67/69 Dart. One of the best looking A bodies ever. That said, with the rust free requirement and budget, 73/76 slant 6 2 door Dart/Scamp's would be more available in your range. Good luck. It may take some time to find the right one, but it will sure be fun when you...

With a 26'' tire at 80 your in the 4k rpm range. If it doesn't happen in 1st or 2nd gear or free revving in that area, i'd suspect it's a issue in the pumpkin. My buds 70' Cuda did the exact same thing and it was the pinion shaft/gears starting to come apart in his 4.56 geared 8.75.

Make sure the throttle cable isn't holding it open. Easy check, just remove the linkage from the TB.

Aquasco in southern Md. 70'-71'. My buddies father dropped us off there almost every weekend during the season so he could spend time with his girlfriend and the wife wouldn't find out...lol :) My first racing was at 75-80 near Frederick Md. in 1974 when i raced a buddies car at 15yrs old after...

Could it be something as simple as a fuel filter acting weird.

How far out are your idle mixture screws. A decent tuned Holley should be no more then 1 1/2 to 1 3/4 out max. If out more then two, you surely have a air leak somewhere near the baseplate. And as i said earlier, make sure your running enough initial timing.

Just a thought, depending on how hard you're hitting the throttle, you may have too high of a float setting in the carb.

That's small town livin right there. Very cool. We're just a few miles from the coast near Charleston so a lot more hectic round here.

Man, that is pretty. :thumbsup:

Del knows way more about the electronics then i'll ever know, but please tell me it still has the original cam/lifters and not a new one. Nothing worse on a new one then a no start condition.

I'd suggest finding someone who could use/want the OD and sell/swap to get a standard 833. It will help your 1st gear issue and with the 3.55's give you the tq multiplication you want in 2 thru 4 vs the 2.92.

I agree. Since your running quality fuel, have you looked into advancing the timing a bit. That may cure your starting and idle issues.

Myself and others have brought up the cam timing issue and i'm still leaning that way. Way back when i was in my teens and still learning, i did several ''dot to dot'' installs and not all, but most left something on the table. And yes, those all never hit the different converters as they...

Reminds me of the engine Steve Clukey ran several years back...

Doubt that intake was stored in CA unless it was on the beach. :)

And looks like the timing tab is cast on the pass side

If it's as nice as you say, that rear wouldn't stop me from buying it. The 7.25 weakest link was the spider gears when free spinning from water/ice and then grabbing hard. The sure grip axles were stronger then most think, but were rare and good ones are almost non existent these days.

You have some gear and the converter is decent enough for that cam, so what is your actual comp ratio and what intake are you running... P.S. Was the cam degreed in...

Lol :)

''OK, thanks all, so more stupidity on my part.....'' ------------------------------------------------------------------ Not even close... Your doing a great job makin' it right. Being anal about building things is a positive trait...Ask me how i know... :)

Steve, don't panic just yet. Imo, the rings don't fully seat until the've been under load, like several 4grand decel's in gear, and that can't be replicated on a run stand. Just 1 cyl is a concern thou. Wish i had a quick solution, but if i think of something i'll chime in.

First off, don't worry about the .700 lift numbers. I'd be concerned about the 104 cl vs a 2k cruise rpm. That said, keeping your current exhaust, i think you'd be plenty happy with 250ish at .050, low 600'' or so lift cut on a 110/112 cl. With cam availability these days, it may require a...

I'm assuming a mild build, so if the flat tops are stock and the compression is low, the Summit 6900 is my first choice for value. DODGE Summit Racing SUM-6900 Summit Racing™ Classic Camshafts | Summit Racing If by chance the pistons have a decent comp height, with a little more comp, this...

That sucks.

Looks like Jegs may have a Speed-Pro set available. Worth a call... Sealed Power L2316F60: POWERFORGED PISTON - JEGS
