So I have the stock 73 Nova steel driveshaft and the stock aluminum one from the 2002 f body donor car.

I plan on running 450HP on my LS1.

My worry with the steel shaft is that it won't be strong enough. Should I be worried?

Obviously the Aluminum F-body one would be cool to throw in there but will it be too short? Can you have them lengthened? Would it be strong enough?

Thanks.

Compare the 2 driveshafts side by side and determine if the f-body shaft is as long or longer than your original steel shaft. If it is longer than the steel shaft, you can then have it shortened to the correct length You cannot lengthen a driveshaft without retubing it completely

You can get an entire custom drive shaft made for under 200.

Steel?

It is shorter than the factory Nova shaft, but the T56 is longer than the TH350 that came out.

as someone who just had a under $200 steel shaft fail last summer (ls1 67,carnage in my thread) I would love to go back and get a real performance shaft made the first time and save myself buying the new trans, exhaust, driveshaft and fixing floorpans... just a thought.

Go onto dennys driveshaft and they will show you how to measure for the correct driveshaft length.

Thanks for the input, this is what I was worried about with the stock Nova Shaft. Did you end up with a performance steel one, aluminum, or CF?

I bought a 3.5" steel driveshaft....I was told it will hold by the driveshaft maker it will hold 1000 WHP and I have hit with 600+ HP...no issues.

Just my 2 cents

Anything can fail, I paid 160 for mine but i supplied the trans yoke. Had it now for 8 years. and Shortened twice, 20.00 each time for different transmissions. Ive put just about 50k miles in the past 2 years. Still rock solid.

74novacustom

yes steel.

I had a brand new 3" steel from Fort wane Driveline and it was perfect for 3 years, including several runs at the dragstrip and hard street miles @ 530 RWHP and it was perfect 5 seconds before it had its way with the underside of my car ...they dont give warning..

New shaft is from PSI
3.5" .125 wall DOM 6061 aluminum, 1350 u joints.

I appreciate your input. Were you running a driveshaft loop? What broke on the shaft?
