What's a 455 worth these days?

[fleming442]

Buick people usually prefer "virgin" blocks so that will partly determine the price. The 75/6 heads are the worst ones by far, but if yours is a 70/71 it will have pretty good heads. If it's stock internally, the 70 will be worth more because of the higher compression. If it has good oil pressure with 10w30 oil (change the oil so you know for sure the dude didn't just fill it with 20w50) with a good ac delco filter then that is a BIG selling point for a Buick. Stock spec for oil pressure is only 36psi at 3,000 rpm, so don't be alarmed if it has that low of pressure. It sounds weird, but 10psi or lower is common at hot off highway idle. 10psi per 1000rpm is the rule. That's the difference between a $200 core or an $800 drop in and go engine. Maybe spend $100 and have the car chassis dyno'd? Not entirely necessary, but it will give a perspective buyer an idea of what they're potentially working with.

Lastly, afaik, it takes some engine mount ****ery to get a 455 buick sitting in there right, keep that in mind when selecting a new engine if you sell this one.

Interesting to see the prices all over the place. Just a cursory glance around here is $500 for a core.

Maybe I should look around other areas when I keep an eye out for a Pontiac 400 because around here, as they're a bit expensive.

I sold my short block Olds 455 for $500. Good riddance. The 1970 W 30 intake that it had brought $1200 and sold in two days

Don't think I would buy one half done.. there has got to be a reason they quit, and I don't want to find it!

I'd take one that started and ran, preferably untouched and produced between '67 and '71.. It wouldn't even make an appearance in my garage, it would go straight to the machine shop for a complete tear down, hot tank, sonic check and rebuild.. 20 over, raise the cr a little.. nice 276/286 roller..

that being said I’ll go 300 bucks sight unseen for your Buick 455

And pick it up if you’re in PGH. My ‘57 F100 would love that engine.
