64 C-Body bolt in driveshaft loop

[NitrousTuner1]

Got this made up for the 64 300K.
It only requires 2 holes to be drilled in the trans crossmember. We might make them complete bolt in IF there's enough interest. As many know that front CV style joint is the weak spot. After doing a strong build on the 413 it was a concern so we addressed it.
Here's a few pic's

2nd try is a charm....

How many C-bodies have pole-vaulted themselves as a result of a broken driveshaft?

The only car that I recall hearing about was Polara Dave's and it was his tail shaft that shattered due to a broken output shaft. I can't recall if the driveshaft dropped out or not...

What do you mean by "CV style joint"...was this something unique to the slab era cars?

 

[FURYGT]

To many bolts IMHO. I had one made for my’68 Sport Fury that is welded and only has bolt holes for the transmission cross member. I was doing drag racing with my car and wanted an extra measure of safety.

It's to save your legs/feet & floor pan Not the movie stuff of pole-vaulting.
And they use a telescopic cv-joint off the a bolted trans flange off the output shaft

I think he is referring to the ball and trunnion joint used up to the '65 models.

Same as 75% been using on B & E bodies for decades. No ones ever had a issue with much much longer units. Watched multiple break in Vegas

 

[3C's & a D?]

It only has to do it's job once, and hopefully it never actually has to do anything. A worthwhile improvement/Insurance!

I like it! I installed one earlier this year, I ended up buying a universal one from Summit, cutting it down and reshaping it a little, and then mounted it to the floor with rivnuts. Would've totally bought yours if it was available at the time.

 

[NitrousTuner1]

Thanks I'm ready to put it to the test soon!

I haven't seen one of the long ram crossrams before with aftermarket carbs. That looks slick!

Luckily this is a Long-short version as half the length is divided. The long version really falls on its face above 3800rpm.
But we did some ported 440 Source aluminum heads, zero decked block, custom ground Schneider Racing hydraulic roller, ported cast headers, should be a BEAST to say the least

 

[Blusmbl]

Those 440 source heads really wake up with port work too, and that sounds like a great use case for a hydraulic roller.

Is it a 413 or did you go bigger while it was apart?

Yeah they are a Great option for the $
We gained huge on the exhaust side. Their poor valve job seen 6-7% increase in flow alone. And yes it was still a standard bore 413 so we just went .030 over with some gapless Total Seals. It's in a real Letter car as well. Had Wheel Vintiques make some 15 x 10.5 steel wheels & put a fake whilte wall on the Mickey Thompsons

That's outstanding, I love the idea of the added whitewalls on drag radials!
