I have a question. I found a 1972 455 with "C" heads (not sure how much work done to the heads, supposedley alot), Edelbrock intake, Edelbrock 750 carb, ceramic headers, windage tray in pan, with other misc. goodies. The guy says it should dyno at 450hp or better. He is asking $5000.00 for the works plus the exhaust all the way to the back. I am thinking pretty good deal since I heard that rebuilding a olds is extremely excpensinve.
Any input on the price of this one verses the cost rebuilding one myself to achieve 450 hp?

 

Tell him to put it on a dyno, and provide you with documentation. You should be able to pull 450 hp out of a 455 for a lot less than that,

 

There's a good amount of hardware there,to only achieve 450hp,UNLESS that is rear wheel HP figures.Get more info about the engine.How long ago it was built,all the parts installed,etc.

 

Has the engine ever been run? I'm always skeptical of expensive motors that have never been installed or fired and are being sold at a loss.

 

X2 on Joe's comment. Like buying a pig in a poke

 

X2 on above. Buyer beware. Like to know the details as I have similar motor.

 

Heck,I'm skeptical about buying any mechanical device.Everyone thinks they have a hotrod,& most aren't even close.

 

nothing like a can of paint to add $3000 to a $300 eng.

 

My 425 made 454 HP for about half that.
