Hey guys, was wondering if anyone can look up torque specs on a 454 we're rebuilding. I believe it's a 1990 block, 4-bolt main, but it could be from anywhere in that era. I need the main caps, rod caps and head bolt torque specs please. 5/16 on the rods. Thanks. Hopefully, I'll be getting his old block and I can sqeeze it in my IROC

All specs in ft/lbs for cast iron case/heads:

Heads: 80
Con rods: 50
Main cap bolts: Inner - 110, Outer - 100
Flywheel: 65
Balancer: 85
Intake: 30
Rocker studs: 50

Remember to clean and lubricate the threads with clean engine oil before torquing, and run torque sequence in three steps - 50%, 85%, and full final torque.

Thanks Vader! Helps out a lot. We're kind of in bind right now. Bought a Crane from Cheif Engines here and seems that one of the lobes wasn't ground right. Hits and won't go past the cam bearing ... great!

never seen it before, but you know what they say ... first time for everything. Here with a professional race engine builder and he says that it isn't ground right .... man oh man .... Crane screwed up ....
