Driveshaft depth in tail housing

Just wondering everyones thoughts on how much the drive shaft should be on the tail shaft.I measured my shaft(drive shaft part that goes into tranny) and was 3 5/8" and when at ride height is only in 1 1/4" of spline contact seems really low to me.Its a th400 tranny on a mild 350 chevy small block.Was this way when I bought it and seemed to be ok driving but seems low or I should say I dont like it.I plan on getting lengthened 1 3/4" but just wanted to see what everyone else thought about it.Thanks

It should stick out about 3/4" of an inch from fully bottomed.

Depends on yoke. A lot of prople use the truck type yoke that isn't designed to slip. This has to be set up with short spline engagement.

Make sure it doesn't bottom out at any point in your suspension travel.

I had one come loose, it looked slightly short,I figured it'll probably be okay. The mistake I made I went like hell across the bumpy section of the road and damn thing fell out. Dig around and see if you can find a longer yoke,.there are different distances in the joint section, cheaper than getting it lengthened
