Built 455 in Akron Ohio

I am debating whether to part out or sell as a whole the 455 in my 1966 Le Mans. Runs PERFECT A/F ratios and doesnt burn a drop of oil.
I am building a ( goal ) 700 rwhp turbo LQ4 with a 4L80E to replace it.
I will not be able to get parts out or the motor for about 30-60 days because we are in the middle of a move. Just wanted to see if there was interest on here before I take it to the swap meet.

Details are:

1973 455 block bored .060

Bottom End:
-Stock crank and caps with ARP studs, Melling pump, Tomahawk windage tray, stock oil pan
-Eagle Rods with ARP bolts, forged speed pro pistons and moly rings
-After market damper from BOP, cannot remember brand
- Steel Hays flywheel with a zoom 26 spline clutch hangs off the back which I will sell with the TKO600 unless your interested in both.


Heads and Valve train:
-KRE D-port heads cnc machined by SD Performance to 292cfm @ .500 lift, stainless 2.11/1.77 valves, ARP head bolts, ARP 7/16 rocker studs,
1.5 ratio Harland Sharp Rockers, Pontiac logo aluminum valve covers.
-Cam is a custom grind roller hydraulic "Old Faithful" by SD Performance with chromemoly push rods.
236/245 dur @ .050" lift .578"/.582" lift with 1.52 ratio rockers 112 lobe separation, double roller high end chain.
BOP tomahawk high clearance valley pan with PCV provision.

Intake and Fuel:
Holley Sniper EFI ( bump the key in any temp and it runs perfectly ill never own another carb in my life! ) on top of a Edlebrock Performer RPM with a billet distributor.

Accesories:
SI10 chrome 120 amp alternator, power steering pump, water pump and all pulleys, air cleaner included too.

Headers:
Ceramic coated Dougs headers fit for 1966 GTO Le Mans and Tempest, some light scuffs from installing. Might fit 65s and 67s too. I dont know 100%.. $400.

I am not sure what to ask for everything but since the Forum requires a price lets start at something like $5,000 for the motor. No headers or transmission.
I have no idea what to ask for this engine. Its in my 66 Le Mans that gets driven 2500 miles a year max. The motor has two seasons on it and never raced.
One thing I do know is my car moves out with this engine! It is mated to a TKO600 5 speed which will come with the bell housing flywheel and clutch and is for sale separate.
If you are interested in the complete engine you can hear it run and watch the gauges first then come back 48 hours later and itll be on a stand for you.

MAKE OFFERS ON THE WHOLE PACKAGE OR PARTS! I might end up taking off the efi and selling it separate. Heads separate too but the short block will stay complete.

TKO600 with Pontiac bellhousing, Hays flywheel, Zoom clutch and hurst shifter $2,000
Heads complete with rockers and valve covers $2000
Dougs Ceramic Headers for 1966 $400
Short block with forged internals, roller cam, lifters and valley pan ( no distributor ) $2500
EFI Sniper setup with Eddy RPM manifold and phased distributor for push button timing adjustments $1000

You outta see her on a road course, or a quarter mile

One thing is for sure, a .060 over 455 block is not worth anything, by itself.

Should be able to sell the heads with no problem. And possibly the cam/lifters.

Hope you have better luck selling your 455 than I've had, selling mine. I haven't even had a decent lowball offer. And it has less than 2 street miles & no track time.

Hello,
I would be interested in the EFI system, what model or version number is it? Did it have a return gas line or was it returnless? What actually comes with the system?
Also, I would be interested in the TKO transmission and associated parts. Did you have the offset shifter install so it would come through the original console position? What are the first gear ratio and 5th gear ratio on the 600? Are you keeping the driveshaft and the transmission cross member?
May as well throw in the headers. Did you have a local place do the "hot coat" If so, you could call them and see how much it would be, to touch them up a little? I would PM you but I don't know how to do that just yet.
Maybe you can post a few pictures of what you have. Is it Ok to drop your email in a reply? Or just ask for a PM.
Thanks

I am interested in the motor and heads...

A few questions:

What compression ratio is the setup?

Did you dyno the setup?

Are the pistons dished ?

Who built the motor and when?

How many miles are on the motor?

Thanks

1965 GTO Convertible 3 speed tri-power drum brakes originally

Current setup:
400 cu in with tri-power
4 speed Muncie
