Re: RARE ALUM HEAD
Wow, that is early. Pretty much right at the debut of the modern Mark IV big block. I would have to say though that your guess of Chaparelle usage to probably be correct. That team had some very special equipment from GM that the public could not acquire. Love to see some pics.

Re: RARE ALUM HEAD
Eary is right and Type 'O' castings...C
 L!.I could be wrong but don't believe Jim Hall or even McLaren were running MK1V's until the '67 cars?. I'd be leaning more towards a Corvette application, maybe some Mickey Thompson road racer...actually when did they start building the '66 L88's?. Yes the '66 L88 not '67...a select few got them, our hero Yenko for one also Penske.. There was a bunch of aluminum engine action going on at GM around that era w/ the CERV cars etc and although I don't think they ever did it, wasn't there some plan for putting a MK1V into the XP819 rear engine 'Vette?. Even the original SB was all aluminum...and necessary w/ that rear overhang!. A set would go nice on a Z16!. ~ Pete

Re: RARE ALUM HEAD
Would love to see pics of both the Big Block and Small Block 0- heads...
 Do you know any history on your small block heads?

Re: RARE ALUM HEAD
At the moment my heads are at Jerry M's aluminum repair guy..The one head had a prior repair that was really ugly...the only thing I know about them is that there was a pic. of a motor years ago on the cover of Hot Rod I believe with these head...they were for nascar i believe...a precurser to the fuelie...One real interesting thing about them is that the exhaust manifold bolt holes in the heads are at 45 degrees to each exhaust port centerline..they dont line up straight across..Someone would have to make custom flanges for headaers to work...When I get them back I'll post a pic....that remins me...its been a while...I'll have to give Jerry a call...
does anyone have that magazine??
