L8t 427 Whipple charged Denali

[WestTxDenali]

So I’m in the middle of swapping my tired l86 out with a l8t stroker with a gen 5 whipple on top with all the supporting mods. Trans was built by tkr to hold 1000hp with a circle d billet converter. The issue that I am running into is a good choice for a drive shaft. Seeing that it’s 65 inches critical speed is going to be an issue. Does anyone have a go to for long high horse power drive shafts?

I dunno your answer, but keep updating this build!

I’ll try my best. I work out of town a lot and am hoping to have my short block up on the stand next week to get pushrod lengths and what not.

I was going to reach out to them on Monday and see what they might have to offer

Quick update. I reached out to gulf coast driveline and ended up scoring a 4 inch t8 driveshaft that will hold well over 1000hp. For anyone wondering a 2wd shaft on a swb is 56 inches center to center without the yoke.

Quick update before I get the heads back on. Got the pushrods measured out all within 7.95 to 7.97 with the Johnson tie bar lifters. Still waiting on the c5r timing chain to come in from Katech. Ended up ditching vvt all together and went with the LME set up. For the money this piece is mint. Super quality and an amazing fit. Had to go ahead and ditch the crap rubber engine mounts and went with atomic. Again these guys knocked it out of the park with the fit and quality.
The head gaskets should be here either Monday or Tuesday and then I’ll have to head back to work over in midland for a few weeks. Over all I’m super stoked for the build and the wife is getting pretty excited for have her Mommy Missile just about buttoned up.

Fic lt4 30 over on the high side walbro 525 on the low side. Gpi cam has a 32 over fuel lobe and then a lt4 high side pump. Unfortunately there is no E85 close to me at all and with this being a daily driver driving 45 minutes to fill up isnt in the picture. It’ll be tuned on 91 pump gas. I’m hoping to see 700ish to the wheel with low boost.
