Conversion driveshaft options?

[destroked 99]

I have to lengthen my front shaft and shorten the rear on my 99 ford reg cab long bed. I was curious how well the factory 1350 joint shafts were holding up?
I should be right at or maybe a little north of 600hp with my engine build and am concerned that they wont hold up. This is a street only truck, maybe a few dyno runs and some playing around on the street. No sled pulling/dragracing.Now the kicker to this is the truck is lifted 8" with 38s. My gut tells me to go 1410 on the rear shaft, but my bank account is throwing fits!!

Any thoughts would be much appreciated!

Trust your gut, wait for your bank account to catch up then do it right the first time, it will be cheaper in the long run.

1410 is as big as i can go with the required cv to deal with the angle of the driveline.

Thats what im planning on doing, thanks!!!!
I wish i had never lifted this truck now, if it was lower i could go up to 1480, but i think 1410s will hold past wat the ford 10.5 can take.
