70 dart 470 ci drag car build.

I got my custom driveshaft yesterday.
47 inch long. It's 3 inch mild steel with Spicer weld ends and billet slip yoke. 1350 u joints.
I had a local racer/machinist do it for me.
I originally wanted to go with 3.5 or 4 inch.
He assured me 3 inch mild steel is plenty.
He has a trans brake big tire car that is heavier and has had his in his car for many seasons.
So I trust what he says. Very nice quality.
And it fits perfectly in between my welded in safety loops.

He does nice work. I’m going 3.5 inch. Maybe 4. I wish he did aluminum because I would definitely do 4 inch if he did.

He'll tell you the same thing, mark Williams has 3 inch rated at 1000 HP.
It is just preference but he's leaving at 5k off the trans brake with 3 inch, so 3 inch will be just fine for me foot braking.

Oh and by the way there's just one 5 gram weight and tiny tack welds.
 
3 months 8 days later I got a chance to get back out to the car.
I wasn't happy with how much tire clearance I had and last week I got a good idea from a posted photo by a very helpful member @71Demon528 thanks RJ.
So I took that idea and trimmed another 2 inches forward into the rockers.
I'm glad to have had time to get out there and work.
Yesterday I did some measurements and got a scare but it was false when the car got the tires on the ground.

Nothin like a little extra tire clearance in there for some insurance. And the tire you are running will work very well on that car. As you have seen, we are running that same tire on my dad's car and it works extremely well.

Yeah, I'm glad I get to see it doing really good work
 
Well since I made a big open hole I took the opportunity to take more weight out of the car.
My scale batteries died right now lol .
If I had to guess, it's around 25-30 pounds

Well done, doors hide a lot of weight. Dropping mine to tear them apart I slashed my palm pretty darn good when one got away from me. I have used my tranny jack under them ever since. I rigged it up so I can raise it with my foot if my hands are tied up.

Tranny Jack is a good idea.
I'm working on my doors right now, it's a little more difficult than the quality glass.
I think I'm going to cut out a strategic hole so I can easily get my wing window frames out.
Unless anyone can tell me where the hidden bolt is
 
Okay I have 1 tub 1/2 *** mocked up.
Needs more trimming and finished but the notch I made into the rocker box really helped like a 3rd hand.

Of course the new goal is first race of the season.
I need to get a converter and basically put it all together.
 
I only had a couple hours this weekend to work out in the garage.
My good buddy Tim brought me over a lathe, that he went out of his way to get and give to me for nothing (except for the help I'll gladly give).
Very cool new toy.
I was going to try and mock up my anti-roll bar and of course the box I got had the parts kit open and so there was a lot of metal banging together.
I put the bushings on yesterday and the got stuck so bad I had to press them back off. Turns out the bar was about .008 bigger than the id of the PTFE bushings.
I took it to work and put it on the crank lathe and polished it until it was really close and finished up the bushing on the rod hone. Now the bar turns easily in the bushings.

Oh yeah I also will be installing a much larger duration camshaft thanks to a fabo for sale ad.
.620 purple shaft which is 275 & 275. So it's much more race engine vs the 264-268.
