Finally got a moment to test fit the main bearings and take the block, crank, pistons to the machine shop for verification of sizes and clearances:
Long bolts on the inside!:
Discrepancy right off - #3 is the thrust bearing and the rotating assembly included Mahle/Clevite bearings - the bearing tang is opposite an LS style engine! Quick call to Texas Speed confirmed one is to grind off the tang. Interesting...I supposed the flanges on the side position the bearing sufficiently...slow grind to avoid damage:
Bearing tang removed with delicate touch of a Dremel...seems odd:
My chamfered lower timing gear that Texas Speed neglected to send/install - finally showed up (free shipping though!):
More to folllow!
