I found it on a couple dodge forums and one was a guy restoring one (where pic came from) and stated - the sledgehammer marks were factory (factory being the Hurst factory) and he left them there for that reason.

"Chrysler's precision engineering inspired the factory to approach the hemi shock-tower clearance challenge with a sledge hammer. This is one of the uniquely crude features you could expect to be included with your freshly delivered Hemi Dodge Dart in 1968." from http://moparsbymosher.com/projects/hemidart/hemidart.htm

Double check with my father and checked a couple of books out of his Chrysler library, and it all began at Grand Spalding Dodge which was a dealership in California. It initially began with them placing 383's in Darts, but they put a hemi in one particular dart. Chrysler took notice and began ordering these cars on a special order basis. They shipped these bare bone Darts out to a factory somewhere in California, old man thinks it could have possibly been a Hurst factory, books only specify a factory out of California. The Hemi's dropped in with regular HP manifolds, and at most the exhaust pipe near the starter had to be pinched a bit to fit between the starter and frame rail.

No they were not street legal. The sledgehammer marks are probably from a previous owner because these were race cars and often the motors needed to get rebuilt. And we all now how some of us get pissed off when stuff doesn't fit. I highly doubt Chrysler would accept cars with smashed in fenders like that.

I don't have all the specs, but the Caroll Shelby's book on Chryslers and "The History of Chrysler" both specify 2.3 0-60 times and 10.2 quarter mile times on stock cheap tires. I can guess the mpg sucked, and weight was definately less than 3000. Hell my malibu weighs right at 3000 and I have an interior, radio, and other stuff.

I agree, my problems with v belts had to do with alignment issues. Your belts have to be spot on or they fly. If Olds would have had the push rod issue fixed on their Hemi, no one would know or care what a Chrysler Hemi was. They came in aluminum too. 400 hp/450 ft/lbs 8 to 1 with .400 lift cam 750 Qjet. 650 hp/500+ft/lbs tq 10.25 to 1 high lift cam and a single 800 cfm Qjet. Was ready for release by 71, too late 🙁 . Supposedly, the in line tube guys have bought the 2 remaining prototypes. We may see one run and drive yet :wink: . They already have one of the 350 Olds aluminum blocks running in their W-31. I want one of those light, heavy duty 4 bolt experimental blocks but they are super rare. Sorry way off topic, I think you will be happy with your build.
If it doesn't go where you want it after tuning, a head swap doesn't take much time.

Well since they weren't street legal then I don't think they could be called the fastest "production" vehicle. And the Buggati Veryon has the fastest top speed, unregulated at 268 I believe, it's still pretty ugly though.

Yeah I'm gonna have to raise the BS flag on a 10.2 timeslip in 1968 on a street tire. That's not even a legit production car. It's basically the same thing as a newer Cobra Jet Mustang. Purely made as a collector/race vehicle, made to attract young buyers to buy from them because they have the fastest, backhalved most gutted car.

10.7 on DR's otherwise untouched. I'm going out on a limb and gonna have to say that I'd love to see a video of a 68' GTS run a sub 11 second timeslip, untouched from when it left Hurst.

Like I said, read Carol Shelby's book "Mopar Engines , Carol Shelby's Speed Secrets", sponsored by Direct Connection published 1982. The book mentions the 68' Hemi Dart specifically in the second part of the Hemi chapter as running 10.2 quarter miles times with a 0-60 2.3 seconds.

Been a while since I posted an update. Spent the last couple weeks putting the motor together and getting all the little nick nacks bolted up. Spent this last weekend going for one final push to get everything done, even though it was freezing cold. Spent thursday and friday finishing fabbing up parts on the motor and trans. Saturday, started to finish putting the main harness back in under the dash and began wiring all the accessories. Had to wire up the fuel pump, lock-up overdrive, electric fan, and maintenance light switch panel. Sunday, finished up the electrical early afternoon, fabbed up the exhaust, and got the ignition system hooked and wired. Now all that's left is weld on some exhaust brackets onto the mufflers.

The plan is to break-in the motor this saturday. I'm going to leave the driveshaft out as I cannot find my master cylinder brake lines and I want to be able to check the tail shaft of the trans to make sure its rotating and what not. Still need to purchase the tubes to relocate the filters to where the charcoal canister and battery used to be. Battery is being relocated to the trunk.
