455 Olds Monte Carlo?

[1984-monte-carlo-ss]

An 83. I have a 70 455 and a 65-66 425 in my garage. The 455 is already .030 over and im thinking about destroking the 455 with the forged 425 crank :idea:

ooo that sounds pretty sick, If I don't get the 455 I'm going to get a 383 stroker in my Monte. and the 455's from 1970 are the best ones I believe

Yea either 70 or 71. Good luck on the 455!

yeaa and thanks good luck to you too!

$1,000, whats wrong with it? I have seen 455 oldsmobiles sold as cores for close to that, although that is high.

Those people must have been high... :lol:
Olds 455 cores go for $300 to $500 all day long, maybe if it had an extremely rare forged steel crank that only came in Toros and 98's with a tow package and were produced from late December of 1967 through early February of 1968 then I can see $1000, I saw one go for that much on eBay but regular J headed 455's are cheap, earlier C, E and G headed cores may go for a little more.
I've picked up a few running 455's for $300 to $375...

An Olds motor is the way to go for some true power and it would be awesome to see someone actually stuff one in a Chevy but usually when someone has thrown a HP figure at you they are full of sh*t and trying to just off load it to some kid unless they have the dyno results to back it up.
500hp is possible and not highly unlikely and very achievable in an Olds 455 but sounds to me like the guy is looking to off load it to some sucker because it's ready to take a crap or it's been beaten to hell... careful.
Only a fool would replace a 500hp, 550 ft-lb Oldsmobile motor for some Chevy small block, listen to what dogshit said... all that horse power aint sh*t if it can't be backed by torque. Take a physics class... I don't care if it has 600hp ON PAPER, if it only has 400ft-lbs of torque forget it, better hope you have a light car and the right gearing.

I woundn't ever buy a used motor for that much money, I don't care if it has receipts... how was it treated?
To me any used motor running or not is a CORE, bar none, regardless of what was done to it. Be careful...
Caveit Emptor...

Do you have the specs on the motor?
Cam, pistons, rods used?
Head work? Valve sizes?

Mondello is just a name, unless it was built by Joe himself from the Tenessee shop it's a crap job built by Lynn in California, that guy has soiled Joes name (god rest his soul) and has done some shitty buisness...
Good luck!

Buy it. It's hard to go wrong with that deal even if something wasn't told and he threw in a little bs. If not you might still have a car that's as fast as that 383 as you probably still have an 70 foot pound torque advantage which would offset the 100hp. Plus it would make a better street car motor at the same et/mph in the same car as you don't have to spin the snot out of it to get the power. It wouldnt require the gear or converter either.

If your boss n buddy have good credibility you are especially good to go.

x2!

Yea I believe they were thats why i said they were out of line haha. Ive still seen people spend close to that though so I really dont think this engine the OP is interested in is a bad if the seller has credibility.
