351W Clutch torque values
 
Appreciate any help. 351W dart block stroked to 427 with Tremec TKO 600. McCleod clutch and aluminum flywheel. Anybody know torque values for flywheel to crank, clutch plate to flywheel, bell housing to block? Should I put any lubricant on the pilot bearing? Appears I have a one piece rear main oil seal leak. If not the seal must be a plug as everything else is bone dry. Appears it started after I used synthetic.

I will be replacing my clutch next week. Plan on 85 ft# aluminum flywheel to crank and 35 ft# pressure plate to flywheel (3/8 bolts). Red locktite on the threads with a lite oil under the head of the bolts for proper torque.

I've heard more than one person say that about switching to synthetic.

As for the bolts, are you using ARP stuff? They have a little different requirement than the factory Ford bolts.

Yes using ARP. Really strange. Prior to synthetic really no leaks maybe a drip combined everywhere. Did a lot of clean up (polished components after removal) and now the only leak is main seal, everything else bone dry. I am 50/50 its a galley plug as the drip runs straight down the block plate, zero on oil pan or engine block. won't know until tranny is out. Thank the lord i have a 4 post lift...

I fear leaks more than any other problem. I hate them and sometimes it seems that there is no rhyme or reason for them.

ARP flywheel bolts...

ARP pressure plate bolts will depend on which ones you have. If you're using a Ford 5/16" bolt, it will be a tad different than the more modern 10mm bolts.

The bellhousing bolts will depend on which bell and which bolts, but I usually torque them somewhere in the 50-60 lb-ft range.
