i have figured out that i have a 1970 455 casting date 9-9-69, casting code XF, casting code 64 on the heads. it is a complete numbers matching engine. anyone out there know if this engine is rare or worth the money put into it?

 

That looks like a Pontiac engine. You're gonna have a little trouble with the crossmember on that Playskool trike, for sure...

1970 Pontiac 455, 370 HP, XF Block, Auto trans, 10.25 CR, 067 Cam, 64 Heads, 1-4 BBL Carb, Carb No. 7040268, Grand Prix /1970 - Only hi comp 455/with 15 or 64 heads Block Casting # 9799140


That is from http://www.wallaceracing.com/enginesearch4.htm

 

I'd say that's worth money to someone restoring an old pontiac. Depends on who you can find to pay for it. Ebay would be the best place to find a large amount of people, i'd recommend posting it there...

 

ebay is what got me curious about if this engine was anything special. there is a fellow asking 7500$ "but it now price" for a 71 455 YE casting code. this motor was in peices, half of which were still covered in crud. it had some machine work done to it. 4 sleeved cylinders. alot of money for something not anywhere close to being as nice as mine. just curious... thaqnks for your input fellas. http://cgi.ebay.com/ebaymotors/1971-...QQcmdZViewItem

 

"nobody wanted to pay near what it's worth", uh ok guy, so part it out, then people will pay more?
That guy isn't a genius, he's very optimistic.

I think you could check out some 2nd gen sites, and ask around there, get a feel for it. Maybe put a $6000 reserve, and start bidding low. If nobody buys it, you can always email the highest bidder and ask what he thinks is reasonable...?

 

i am on the fence about selling it. it would be a real conversation piece in my 89 camaro i just picked up. i guess i really wanted to know if i had something to brag about. again... thanks for all of your input. i appreciate it.

 

Theres a big difference between a 1971 YE 455 HO and the 1970 455. The '71 was a full High Output performance engine with round port heads, cast iron headers, aluminum intake with larger runners, 068 Ram Air camshaft, and a 830 cfm carb. The 197 code heads alone bring about $1500-2000 these days.

The '70 455 is the only high compression 455 made but its more geared toward moving heavy cars around. It a torque monster engine like the Cadillac 472/500 engines. It was sold under 455 HO name in the GTO but its only that in a name. It has a cast iron intake, D-port heads and log style exhaust manifolds. Its comparable to the standard duty '71-76 455 engines had those been high compression.

Its still a good engine and would move a 3500lb 3rd-gen around very quickly. The '70 455 370HP engines are somewhat rare but being they aren't a true HO engine they don't command the big $$$ like '71-72 455 HO and '73-74 SD-455 engines. Your engine is probably worth around $2000. Maybe a little more to the right person.

Your engine is definitely something to brag about, as are all Pontiac engines. Its not a "just another Chebbie" engine!

 

thanks for the info .. that is good to know
