value of a sideoiler
I am thinking of changing motors out of my cobra. I would like to sell the motor I currently have in it but not sure of the value.
It is a 427 sideoiler , 1968 block, bored out to a 482ci. It has Michigan aluminum heads, .705/700 lift. solid roller valve train, shoebeck solid lifters, windfield billet crank, oliver h beam rods, diamond pistons, cloise double roller timing chain, kanton oil pan. it currently has 48mm webers on it but not sure if I want to sell them with the motor. I am thinking the motor value at least 20k but not sure. |
I would cost up the value of your next engine, which may give a better idea.
It may even sway your mind to keep the current engine. Gary |
@ sideoiler427, I spoke with Jeff (1985 CCX) a few week's ago about my date-coded 1965 C5AE-H-block. I have complete history on this motor. As mine came from Holman & Moody to be installed in 66 Merc. stock car, Project was shelved in late 65, and a crew chief from Holman & Moody brought the 427 that year, where it sat (Crated) in his garage up till 5years ago, until the org. owner of my CR (they were friends) brought and had it freshen up here in Wa. state. All number matching (LeMans crank & rods), and just dyno time, I was some what surprised at the value of mine. But then again it would have to go to the right buyer for the kind of dollar figure we discussed (Such as a owner of a real car) As Jeff and I discussed mine could be installed in a full comp Cobra, or in a Ford GT-40 Mk.2 (By the date codes). So I believe that adds to the value of mine. I still believe the value is anything the buyer & seller are happy with, as Gaz64 said, come up with price for your new motor and go from there. My $.02 I would keep that motor :) Nothing like a Sideoiler! Cheers Tom

How far was the block over bored? Compression ratio? Quality of the parts used for the rebuild (only that you can document). Fresh, documented rebuild, or if in the car, how much mileage on the rebuild? Aluminum heads do not offer anything but typical used market value as most sideoiler buyers want a dated set of heads to go along with the block, so the block and what is inside, and the condition of what is inside of the block will be the deciding factor. Intake and carbs will depend a lot on the numbers on the carbs. Low numbers equal a larger dollar figure than higher numbers. I'll leave this up for now and let others extrapolate from here.

In the real world, nothing is ever worth as much as you think it is.:cool:

Might be better to just keep it / store it as a historical piece. You’ll never get the value for it, right or wrong. Build a modern stroker and run the crap out of it!

Ditto

IMHO, nowhere near $20K. $12K to $15K, maybe.

thanks for the input. The motor was bored .30 over and it has a 10.5 compression. Yes is know the only thing that is real is the short block but I have been told not too many around that is why trying to figure the value. It bent a pushrod and broke the rocker shaft on the no. eight piston going to replace the rocker assembly and see if any damage to the camshaft. I want to go in a different direction with the motor and would like to sell this one to offset the cost.

0.030" over is pretty extreme for a stock block 427. I would want to see results of a prior sonic test before I'd even consider it, no matter what the price. Core shift during casting was a real and terrible problem for these blocks.

Yes 0.030 does not leave much room if it needs bored again to true it up, and it should be sonic tested before boring again (if it needs it), but let's not act like it is a boat anchor either. There are a lot of SO blocks out there still running with patches after rods opened holes in it. Blocks can be sleeved. If done properly, no problems. They are relatively rare to find and no more originals will ever be produced. So it does have good value.
In my opinion, now is not a bad time to sell. In another generation or two, very few people will remember what a 427 SO FE engine was, let alone want one. Today there are still more people who would love to have one than exist. Supply verses demand makes an old engine, not worth $100 to the average person, worth $15,000 or $20,000 to the right person. The demand numbers will die off. |

Tight market right now in my humble opinion. Most people think they can build same for half price, sorry but parts cost real money today. You would need to show what you really have to get any firm offers, otherwise you will only get offers from bargain hunters. I would have professional shop tear it down and inspect so strangers would feel more comfortable with making reasonable offer based on third party, they could also get price to refresh. FWIW
