2006 mercruiser 6.2 engine specs
A friend has a pair of 6.2s sbc in his Formula and we are wondering what are the specs on the engine. I know in stock form it makes 320 hp and has vortec heads and a multiport intake. Is the crank cast or forged? What is the rod length and what type? Are the pistons hyperutectic or forged? Do the heads have stainless valves? What are the specs on the cam?

Almost positive it has hypercracking 
(hyperutectic) pistons, PM rods. and steel 4340 crank. Since not 100% sure, I'll dig for info too.

Snips from Manual 31. 1.94, 1.50 valves. Doesn't state rod length, valve type. Heard Rumor were Lunati cranks. Hopefully someone that's been into one will chime in.

Off of memory, some had forged and some had cast cranks.
Hyp pistons
5.7” gm powdered metal rods
there were some (don’t remember if it was years or serial number run or whatever) that had piston issues, the top ring was too close to the top of the piston and they were cracking there.
So I think I just added more confusion haha.
