Guy's is my 67 400ho going to be the same as the 455? Yes right?! 389 , 400 , 455. Never be on the bottom end of an engine on my own.. Thanks guy's!

What were the oil groove serrations like on your crankshaft prior installing the bop lipseal ?
Just wondering as i'm about to do one.
I understand that aggresive serrations are def not ideal, but those seals may be used fine on "smooth" serrations, as instructed by bop.
Im guessing yours hasnt leaked since you've done it ?
Cheers

Great video. Gave me the confidence to put my 2 piece BOP in my 389. Primary difference is that you only fill the caps rotation holes (Not sure if that's the correct term) with sealant (according to instructions). You guys make great vids!
