Got my dads valley tray fixed and sealed. Smoked the engine down and made sure there are no leaks. After we confirmed that, we primed it and fired it up. Tons of vacuum. At dead idle 10" ice cold and as it got warm it began to climb. Turned it down to 7" at fast idle. Was very happy to see that.

We installed a Jones transmission pump this winter and new trans cooler which was no big deal but a nice upgrade for hot lapping and maintaining trans temp.

After running the car, got everything ready to swap valve springs with the new buxton engineering on head valve spring tool. That tool is a work of art, but as we figured, the intakes will all come off in the car easily. The exhausts, NOPE. #1 exhaust which has the most room wont come off as the tool hits the inner fender, as we kind of expected but were hoping for the best. So the engine is coming out so we can do valve springs on the engine stand.

Then onto the next saga, got a call from turbo action about the converter I sent to them to have opened up and gone through. Front pump assembly was trashed, sprag was trashed, and unfortunately they lost their machinist and are unable to fix the converter. Paul Forte is 83 years old and is battling some health issues as he fell and hurt himself a few months back. So a decision had to be made about a converter.

Called ATI and ordered a new bolt together converter for the car which is hopefully going to be here next week or so. So since we are pulling the engine, the trans will come out and I will go through it and clean it "just because".

Ill take pics and post on here when I get it out and apart.

The Barton valve covers showed up this week, wow they are nice. Black wrinkle finish, will make the car look much more nostalgic in my opinion over the covers we were running. The new covers are not light, but hopefully they will come on and off easier than the ones we were running.

Race season is approaching, still lots to do, but we will be ready.

They can be a pain. I have changed Hemi springs in a 65 A990 car. Years ago. Roller cam so the springs were stiff. My buddy's wife did the keepers while I held the spring down. Wedge much easier. Can do them by myself. But 320 on the seat takes some effort. But still takes care not to nick the keepers. Look forward to seeing the results.

Freshly installed I will soon be experiencing the fun myself!

Alway nice to here for the first time. I enjoy mine every summer. Just fired it up this morning for something to do. Along, with several of the other cars since they haven't been fired up in a couple months.

Thanks Doug. Ya its not a fun task. If it wasn't the Barton individual rocker system, and it was a stock style rocker with two shafts, it would be much more doable. But the individual rockers and the engineering of those rockers and the buxton tool make it damn near impossible to do in the car with inner fenders.
 
I have never owned a Gen II hemi. And am dying to see how bad I can screw up.

My '69 GTX is an IDEAL candidate. The car is nowhere near numbers marching. In fact so wrong I'm not 100% sure it's core is a GTX. But fender tag, dash VIN and title says RS23L9G. Everything after that? WRONG! Lol. But it is what it is.

Now I just have to talk myself into pulling a very decent running street 440 for the Hemi life. I'm VERY confident I can screw this up.
 
my hemi build is coming along also. stock style indy roller rockers . i cut off the protrusion on the passenger side at the shock tower for better VC removal.(pic is from somebody else's car marked with black arrows...its been cold and rainy here which gave me a cold so assembly has come to a halt. But its all there, machining done, Soon i can has some of that Hemi fun also. i have already paid the Hemi Tax $$$$$$$$$ (parts prices :( ).

That's what's happening now a days,tax the rich,but Hemi engines can make the rich poor!

Cars or muscle cars period now can do the same...

I've owned 100 & something cars/trucks now,
many were muscle car era cars, 40-ish 68-70 Mopar cars
Hell, now
I'm priced out the hobby for the higher end stuff
I used to buy for $350-$1,500 back in my hay-day

Hell
I almost bought a 426 Hemi 68 Dart Convertible (not org. hemi car) for $6,000
thought that was too much at the time... 1981-ish :BangHead:

he always was flipping some car, a lot of cool MoPars

The same guy was selling a nice yellow 32 Ford 5 window Coupe
with a 426 Street Hemi (needed a lil' work & interior) ran well
& a Dana 60 4.10 narrowed to fit right, N-50/15s outback/Crager's, 727tf w/J-converter,
around the same era/time all for $5k
I think he wanted to trade one of my RRs & some cash
I passed on that one too... :BangHead:

He had an old show-car wild paint
main body yellow & pink, blue, orange graphics down the door & over the qtrs
a 70 Hemi 'cuda, 426 4 speed Pro-street he wanted $8k for,
in like 81-82' (?) a real Hemi car or racecar, that was cut up, but presentable...
I passed on that too, it was a nice build, but was overpriced at the time
still should have bought all of them, saved them for 10 + years
& would've made some serious coin, hindsight... :BangHead:

I'm getting close too. Friend of mine back in '72 or '73 ish had a silver '67 Hemi auto Charger, it had about 54,000 on the odometer. Couldn't sell it at $1,400. Finally let it go for $1,100. Damn, but the gas shortages were on then, remember the high priced regular gas? .54 cents a gallon?
This is my '69 Hemi Road Runner, thinking at one time it was a race car, has a roll cage in it. It's tubbed, ladder bars and tubular front suspension. Took the 4-speed out and went street/race auto from Coan. It's been 2 1/2 years since I bought it , never driven it, was broke when I got it. May start it next week, starting to warm up around here. It will be April before the salt is gone from the roads. Hope that I have done everything correctly, haven't really been quite this deep before. Not getting any younger at 76!

Sorry to hijack, but whoever else’s car this is…. I love the look of the forward snout bars in black against the body color engine bay! I was thinking I was going to put the snout bars on my car outside of the fender aprons, but this look is enticing.
Ultimately, room to access the headers and spark plugs will likely win out, but the eye candy in this picture!

I’m not too familiar with Hemi stuff…. 14 degrees difference between intake and exhaust running duration; Is that normal? Most wedge stuff I’m familiar with utilizes 4-8 degrees more on the exhaust side.

Just make sure to keep them as tight as possible to the inner fender aprons when running a Hemi. I can just barely remove my rocker covers with the engine installed.

like the parts , all but the dual plug valve covers <leakers !!
 
Can’t wait to see how this one runs!
Thanks! It ran good last two seasons but with more vacuum now it should wake it up a little bit. And who knows what the ATI converter may do to its performance. We will find out soon.

LOL!!! Customer of ours had a 440 forever and after a failure two seasons ago he said he always wanted a Hemi. So he approached me at Norwalk and now we are building him a 528 Hemi for his NSS 67. He is only trying to go 10.00 index and my boss was pissed he said "How the hell we supposed to make a Hemi ONLY run 10.00?"
Needless to say, your GTX is a real candidate for a Hemi. No one will fault you. But the Hemi is much more expensive than the wedge.
