Your eBay # is off incorrect but you're probably referring to this one...

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...

VIN 124379N634907

I would say it may be the same as his Ebay user name. https://www.yenko.net/ubbthreads/imag...mlins/hmmm.gif

This VIN is 641 from my 69 COPO.

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. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

This is what it looked like when I first brought it home.

[/ QUOTE ] Rob, I gotta agree with you about not enough piston to fill those #074 chambers! 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.

If my memory isn't failing me [quite possible!], you're talking about a 34cc dome [L72] going into a 118cc chamber [074]...just ballparking it, that combo would be somewhere in the 9:1 range! https://www.yenko.net/ubbthreads/imag...emlins/eek.gif

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