Re: 69 OPO
Your eBay # is off incorrect but you're probably referring to this one...
http://cgi.ebay.com/ebaymotors/1969-DOCU...A1%7C240%3A1308 It'd be interesting to know if the mentioned alum. heads were supplied loose or installed at original vehicle delivery?. Probably best to contact one of these fellas for info on any Scuncio cars...

Re: 69 OPO
I'm curious to know if they did a complete short-block change, or even pistons, when they put the 074s on...otherwise, there ain't near enough piston to fill those chambers! Great looking car, though...

Re: 69 OPO
I'm pretty sure the seller is a memeber here...I would have to do some digging to come up with this username...

Re: 69 OPO
When I picked bought my MN motor a year and a half ago, it had 842's on it dated 8/68. I wondered if they were dealer installed or put on at a later date.
 This is what it looked like when I first brought it home.

I put a set of aluminum #077's on my stock 1970 LS-6 closed chamber motor and it really neutered it down. Sure it's more pump gas friendly and even runs a little cooler but it doesn't have the snap that it used to. I even used a very thin Cometic head gasket (.022, I think) to simulate the original thin steel embossed gasket. Lately, I've been thinking of a piston swap or maybe even putting back on the old #291 iron closed chambers.

And that's a best case scenario, assuming the rest of the clearances/specs are spot on...
