If Mopar had stopped at Electronic Ignition Distributors AFB, AVS and Thermoquads, I'd have been good with that !Those were the days .. Computers suck IMO !

That makes 2 of us … I did love the 6-packs tooIf Mopar had stopped at Electronic Ignition Distributors AFB, AVS and Thermoquads, I'd have been good with that !
Going full mechanical on that setup with a hyper 440 under them, a 4 spd and an educated right foot, produced a huge fun-factor and a nice wailing sound that could be heard blocks away.That makes 2 of us … I did love the 6-packs too
I had old cars many years ago and knew that pinging noise. That is how we tuned our old 6 cylinder Vauxhalls. Top gear at 30mph WOT and if it pinged we would just trim it abit.
Never heard anything like it on this. The guys at HBR in Christchurch had it on their dyno and had no pinging there.
Imagine a thread could ever end up on Ho street!!Going full mechanical on that setup with a hyper 440 under them, a 4 spd and an educated right foot, produced a huge fun-factor and a nice wailing sound that could be heard blocks away.
This thread has turned the corner onto Ho Street.
It does hahaha … or those pesky piston wormsPic number two looks like a shot of something from space lol
Is the 3rd pic the bad piston and rod .. looks like the rod is a new one ….On my own engine, the failure happened so fast there was no time for the obvious signs of detonation other than the tell-tale broken piston.
The spark plug looked fine but the electrode was tapped shut.
And there were small gobs of aluminum on the plug under magnification.
There were smaller pit-marks on the dome, which was from detonation.
The large piston-dome marks were from the piston fragment dancing around looking for an escape route. It did manage to find its way into the Cat when I was on the drive home from the track.
There s nothing like the sound of kicking in the outboard 500 cam secondaries on a six pack ,, I’ll,say more than a wailing sound hahaha . Mine was a 340 with a Holley 6-pack and vacuum secondaries that I modified with jets , springs , metering road and block ,, was externally adjustable without removing the float bowls .. the vacuum set up was more steerable and controlled IMO. My memory s intact lol , the primary was a 350 CFM AND EACH OUTBOARD CARBs WERE 500 cam .. The setup was a up was perfect for economy and full owner .. much better than the 650 and 780 Holley 4 barrels … with the Thermo Quad and the Hollies I was getting around mid 10’s MPG and at the time had a factory 323 ( memory ? ) rear gears single trac that I replaced with a pumpkin type rear from a challenger with 373 gears posi trac .. it had lots to of other mods also .. list was long .. but the MPG improved to right around 17 .. that in itself was surprising to say the least and the power was a lot more than stock ..

HaHaHa..Yes, it does.Pic number two looks like a shot of something from space lol
No, that is the Rod with the damaged piston that was removed from the engine, as is.Is the 3rd pic the bad piston and rod .. looks like the rod is a new one ….
No it was free. The intake valve had batted it around in a circle. No marks on the bore at all except the missing bottom bit.Was that piston jammed in the cylinder??
Knock on wood (my head), I have 103K on mine, no issues other than the leaky PS lines. Did 115mph on the interstate coming to work this morning, with a smile I might add.Just drive lightly until then. Just put forged internals and they are fine.
I really like the ZF 8 speed trans conversion. If I had the money I would do that. Be just like a Track Hawk. Fast and better on gas
Is that a Oak or Mahogany wood head hahahaKnock on wood (my head), I have 103K on mine, no issues other than the leaky PS lines. Did 115mph on the interstate coming to work this morning, with a smile I might add.
Lucky without a doubt … it may have helped when the broken off piston peice escaped the combustion chamber ..No, that is the Rod with the damaged piston that was removed from the engine, as is.
There was no other damage other than an Intake Valve that needed to be lapped to remove embedded Piston material on both the Valve and Valve Seat.
After the Piston popped and tripped the C.E. light due to a no-spark condition, I drove it home (at a reasonable rpm) because I was going to rebuild it anyway. In hindsight, it likely wasn't a good idea but whatever doesn't kill 'ya, makes you stronger they say. Fortunately, the Engine agreed and powered itself home without further incident.
Maybe the flat-earthers could use it for proof!!Pic number two looks like a shot of something from space lol
The Thermoquads had issues that were fixable. At the top of the list were the resin floats that, over time, absorbed gasoline and became rather heavy. Old school brass floats to the rescue! The second oops were the Secondaries that wouldn't open reliably. A short length of quality wire fixed that issue.There s nothing like the sound of kicking in the outboard 500 cam secondaries on a six pack ,, I’ll,say more than a wailing sound hahaha .

The engine was a cast engine 1973 model and not the earlier forged higher compression model.
Right! Proof of flat earth by rottenronnie. You will be famous!!Maybe the flat-earthers could use it for proof!!
Earth has rings too (like Saturn, only different)!!
