Built cobra jet 460 cost value

Wondering if anyone could give me a price on what a fully built 460 would be worth with the following components:
1976 460 block
428 cobra jet heads
blue fender intake manifold
750 holley
double roller chain
shot peened rods
msd ignition
canton oil pan
9.5 to 1 compression
scj spec came
meling high volume pump
balanced, blueprinted and crossdrilled motorsports crank
ss headers
jacobs electronics

motor was built to run on any type gas. horsepower is said to be about 600??? not sure on that but in compression is raised maybe so. What do u think is a good price to pay for this engine????
Thanks.

This is bogus for several reasons. First 428CJ heads are from a different engine family and will not physically fit. Second a 750 carb is smaller than came on the 429CJs. Third, the compression is lower than stock CJs ran. So fully built is also wrong as fully built motors don't run on pump gas. Lastly, what's a came?

What are the casting numbers on the heads? Could be some more of those D3 cobra jet heads. Seems like everytime someone tries to sell a 429 or 460 it has CJ heads on it.

What is a blue fender intake manifold? Never heard that one.

they are nothing but stock passenger car heads without the proper casting numbers, a 750 is plenty on a mild street engine but not enough on a "built" 460.
Also on PI heads you do have to specify if they are 429 or 460 PI heads (they are different) and PI heads are NOT CJ heads although they are good.

Also WHAT motorsport crank? the only "motorsport" cranks for the 385series engines are the 4.3" stroker cranks that use the larger rod journals then the typical stroker cranks. and if it's got a stroker crank in it, then it's not a 460.

If this is an engine you looking at buying I would say run, cause the seller is blowing smoke up somewhere and doesn't have a clue.

As greenhighboy put it, maybe these are the ultra rare D3 cobra jet or the E7TE PI heads and probably has the D7TE 4 bolt main truck block too.

Basically if the guy doesn't know enough to list stuff honestly then I wouldn't trust him on any of it.

do you KNOW they are PI heads? Or were you just told they were? What are the casting numbers, cause without those they it's all advertising, everyone has CJ and PI heads until actual push come to shove and show the numbers.
as to value of true PI heads, more then passenger car heads, less then true CJ heads. power potential falls in the same area.

Like monsterbaby said, it's all advertizing until he produces the head numbers. I wish I had a buck for every 360 became a 390 or a 390 that became a GT or a PI on sale day or better yet a390 that became a 428CJ. Anyone can write whatever they want in their ad. It does not make it so.

I thought Ford 9" rears are 28 Spline? Can you fit 31 Spline?

$15000, run as fast away from that as you can.

If I had a Buck for every 78-79 F100 -F350 that was advertised as a Hi-Boy, and a Buck for every 73-79 F-150 4x4 that was advertised as a Stock 460. I could retire.

The bullet proof rearend developed for NASCAR was a 9" 31 spline unit, which was then used behind all their high performance engines. The 28 spline was the normal rearend for the big cars.
