Trans is a TH350 with shift kit and Hughes 3200 stall going to a 10 bolt with and eaton posi and 3.73 gears. Rear 1" sway bar. Tires are 275/60/15 TA's on the street and the same size TA drag radials for the strip. UMI tube upper and lower control arms frame braces. The car will be stock weight but currently working on lower its stance and firming up the suspension.

Very Nice, Dave! Since I'm not a skilled mechanic and don't have all the necessary machinery, I had one built a couple years ago. It's incredible when it comes to life for the first time! Sends chills up your back.

Good luck with it!!

Sounds cool Dave!

Just wondering... have you thought about going to 275/50x15 drag radials?

With my 3.90 gears I run 255/70x15 on the street(29" tall) and 275/50x15 drag radials (approx. 26" tall) at the track to get my effective gearing a little lower.

Decided to go with a vac secondary carb so I bit the bullet and ordered one today. Got the Holley 770 alum street avenger. Hoping it will keep things more streetable then the dbl pumper.

Also picking up a 6AL2 box. Cannot wait to hear it run :)

Man I cannot wait to hear this motor fire up for the first time in close to a year. Be nice not to foul plugs left and right to. The old dbl pumper hated the street.

I considered getting the air gap manifold but think the Dart should do fine.

Very respectable build Dave. I'll bet you're gonna LOVE it.

I am planning to use 275 drag radials for the track and 18's, still undecided what size yet, for the street.

Very cool combo!

I wanted to come check this out again, to see if it was the engine going in the '72. Yup.

That ought to make some great power. Those pistons must be domes to be able to run those heads and that cam together. With the rest of the drivetrain matched up and the car ready to squat and go, you'll be giving some bbc's a lesson or two.:p

Got to hear her fire up today. Man it sounds sweet. Cannot wait to get behind the wheel !

Bumping this one up. What is going on with the engine and driving?

Just got news theres more metal shavings in the oil then I would like.
Not jumping to conclusions but if there is more damage, then I am considering stroking this motor. I am going to show how little I know about motors with my next question.

I know the entire rotating assembly would have to be changed but could I reuse any of the old parts. Heads ? Thanks

Dave

yes! heads pushrods intake rockers what is changed is the crank, rods, pistons,balancer % flywheel everything else is the same

Sounds expensive.

You can buy stroker kits, with everything in them. I kind of lean towards using GM parts, but Eagle ans Scat both make kits.

You'll definitely be able to use your top end the way it is...carb, intake, valvetrain, distributor.

Plenty of room under the hood of the 72, good luck!

Ha Ha, pulling this thread out of the weeds !! I saw this car today sitting in the garage....Nice looking ride Grumpy ;) Anyway, did you end up stroking the motor ?? It's not unusual too see alot of metal "slivers" or "shavings" after a fresh rebuild in the oil. Now if they are larger "chunks" and you see perhaps some copper mixed in there, then I'd be worrying :D. Nice car though man !!!


GD

Thanks GD. Just one correction to your post. The car is actually mine. :)

Here is a link to what we actually did with the motor.

Get him Ms Grumpy ,Joan lets folks know the vert is HERS too.

i wish I could get my wife into my cars as much as you are Ms Grumpy!

No you don't, then its double the costs ! :D

Lol. ya you're right about that. It still would be alright with me.

Yeah, but just think about it. What did I get for my birthday....a new set of tires and rims. All the things you would want to buy, you could get away with as buying for a holiday, anniversary or birthday. My family thinks I am nuts for being so into cars. I am just lucky that I have a guy who understands my addiction !

Thats awesome! I think Grumpy is the lucky one! lol
