Driveshafts have to be right. They have to be balanced and they need to be exactly straight. Your buddy might be a great welder but pipe sits still. Driveshafts spin at engine rpm. If you ever saw a driveshaft break at speed you wouldnt be asking this question. Driveshaft work is relatively cheap. Last one we had built was guaranteed to 1200hp and with them supplying yokes and u joints was 300 bucks made from scratch.

Yes it is. They built the shaft on my 67 belvedere. And it had a trans brake and a 750hp stroker 440. That shaft took it like a champ

I always shorten my own. I cut them, put it together with the joints in phase, tack it back together, install it in the truck and spin it to get it dead on straight, and weld it up. never had one break, and my truck will twist up the frame when I get on it. but if you're not comfortable doing it def pay someone else that can.
