Make sure you drill a hole in the gallery plug behind the disy gear

Bored and honed, Tunnel honed to suit ARP mains bolts, one piece rear seal, zero decked, clearance ground for stroker crank,balanced 0.4gm

the more oil on the cam chain the better, plus it helps lubricate the thrust surface between the cam and the retaining plate.

Why?? Are you quietly expecting this rebuild to turn to sh*t..,

Do beg my pardon, what is "ol"?

Question time again, have purchased a set of Wiseco forged pistons, now there is no markings, dots, arrows on the tops to indicate piston orientation,
And there is valve relief machining grooves in the tops on one side only, am assuming these reliefs go to the intake/valley side of the cylinder, so once assembled all reliefs should be pointing to the centre of the engine,
Also with connecting rods (scat I beams) the Larger chamfer goes to the crank journal side and the lesser chamfer side goes against it "paired rod"
even if the markings on the mains ends dont match the markings on its "paired rod" if that makes sense, l am not talking about rod and caps, they are numbered and you cant possibly get them wrong, Am l correct??

what is the part number on the pistons?

intake valve relief goes to the rear on the left side and to the front on the right side but it should have a relief for the exhaust too unless it is a boss 302 or 251 cleveland piston.

So the rods, the fly cuts for the bearings go to the center of the engine thats it, this then will have the chamfer to the crank throw.
