Oh, that's right - Mk IIS. Thanks, Verne!

The &quot;Z-33&quot; tribute was a creation by Roger Sortino (who also owned a few Z-11s) as something Chevy &quot;could&quot; have built, but never did. HE lettered it up with Hayden Proffitt's name and on the back panel it said &quot;Hayden's last ride&quot;. Hayden wasn't too happy about that. [img]<<GRAEMLIN_URL>>/haha.gif[/img]

PS: I meant to say the first MK-II was a 396, not a 409 cid. Sorry for the error.

Yes, Harrell's Nova had a Z-11 in it.

Do you know anything about a 402? Seems that the Chevy II GT was supposed to receive this motor but nothing I've seen outside of GM paperwork suggests anything about this motor.

Re: Who knows about the Mk II motor? (re: Bill Thomas)
 

Never heard ANYTHING about a 402 connected to a MK-II. It's merely a .030&quot; over 396. I HIGHLY doubt that the MK-II engineers bothered to make oversize pistons for that engine.

The 402 was referred to as 4x4, which I could not figure out but someone told me it's likely bore x stroke. I used a calculator and that's what it is.

Re: Who knows about the Mk II motor? (re: Bill Thomas)
 

Chevy II GT as in '62-'63 Fastbacks? Think could have had anything but SB 377 was the/a hot item. 4x4 would be trying to fit a 4&quot; stroke in there. Don't think that is a good idea.

That Hot Rod article is short but nice info. The video adds little more. Too bad they didn't run with the original manifolds/headers. That engine seems to be a stock MkII 427 HiPerf by the power output. Video said power was leaning over ~5,700... think should be like ~6,300 from data history.

Yes, the fastbacks.
