429 scj block
Hey guys,
What is a standard bore 70 429 scj 4 bolt bare block worth?
There is one for sale here locally and the only history on a 429 4 bolt block sold on Ebay is a 69 boss block.
Thanks,
Steve

I purchased two at one time around 1986-87. They cost me $450 each plus shipping (both came from the same person). Since that was over 15 years ago...I'd say they are worth more than that now. Look up Aldridge Automotive in Portland, Oregon and give them a call, they should be able to give you a good idea what one is worth.

I thought it was too steep also and left both of them setting. They were 4 bolt main blocks and the numbers were correct. I've watched a couple on ebay go even higher than that. You have some of these collectors and restorers that have to have all the correct numbers matching car and will pay anything to get it. I guess along with them and these older parts getting scarcer by the day is what drives the price up and up.

The 429 SCJ blocks were NOT splayed, the main bolts run 90 degrees from the block surface.

This guy is a decent way to check 385 component prices:

He lists 4-bolt CJ/SCJ bare blocks from $1100....

The 429 boss block had bolt in freeze plugs and the front crank cap was also a 4 bolt cap I think leaving only the rear one not having 4 bolts. I do not recall any cross bolts on any ford motor other than the 427. FE motors had the crank sitting inside the block or between the block walls allowing them to be cross bolted. The 460 has the crank sitting on the bottom of the block not between the block walls like an FE motor so cross bolting a 460 would be very hard to do since theres nothing to cross bolt to.
I may be mistaken but all CJ motors where 2 bolt blocks but had the better rods. Football head rod bolts. The only 4 bolt blocks where the SCJ and the boss. A boos 429 block will bring more than twice the value of a SCJ.
I don't think I could pay $800 for an SCJ block but I did pay $450 10 years ago for one. Only to later blow the motor and crack the block. A good street engine will be fine with a 2 bolt block. A strret engine will ever see the rpm's that would require a 4 bolt block.

All CJ engines were 2-bolt mains, football rods and cast pistons. Some 4-bolt blocks showed up in '71 CJs as Ford wound down production of the CJ/SCJ.
As a sidenote, Ford technical bulletins of that era spec'd forged SCJ pistons as service replacements for the CJ. The CJ was used as the police interceptor engine in '70/71 and CJ cast pistons were failing at the skirt in extended, high rpm pursuits.
I'm in agreement 4-bolt main blocks should be left for the restoration crowd. 2-bolt blocks will handle 700hp and for anything above that a Ford Racing 4-bolt block is a far better selection.

A key for the 385 series block is to use a dremel tool to open up and polish both the supply and return oil gallery on the oil filter mount and the supply to the block on the oil pump mount. HV oil pumps are great, but useless on this motor if you do not work these a little. I also drill or auger out 2 holes in the back corners of the lifter valley to greatly aid oil return. Oil pooling here is a problem. Good luck.
