IIRC they are 3/8 threads so about 35 ft-lb should be fine- may add threadlocker too

I've a 68 010 4 Bolt Block with 67 Grumpy Spec'd 281 Heads. I used the OEM Vette Windage-Tray and 4 Qt Pan that Bolts to the outer Studs of the 4 Bolt Main Bolt - which basically was the man reason I choose the 4 Bolt and probably the same Tray & Pan used for the DZ 302. I run the large Journal Forged 3.25" Stoke 68 327 Crank and forged TRW-L2166NF30 pistons to give me an 11:1 Static Compression. I choose the Sigerson F-296-1 SFT Cam which gives me an 8.2:1 Dynamic Compression - She's a 8000+rpm motor and has been shelved until I tire of my 625Hp 7000rpm LS4 - One of these days, I want to get back into a LT1 SBC with a M21 & 3.55 Gears.
