Re: Hardblock?
John, I've attached the sonic check of the three 273 blocks I had sonic checked in January. The "orange" block checked worse than the "greasy" and "rusty" blocks. None of them were all they great. I think I will build a 2bbl engine with one of them, save the best for a 4bbl engine after I get my feet wet (hopefully not literally) with the 2bbl engine on building Stocker engines.

Re: Hardblock?
Years ago a stocker was only allowed .035 over. The stock blocks were pretty good at that size. Now with the more overbore the need for block fill or the better aftermarket blocks is needed. I personally have not had good luck filling the stock blocks and running at .060 . several have cracked the cylinders. You will be much better off to save a few bucks and get the aftermarket block. They are much stronger in the cylinder walls and deck. The bores will stay round and straight. The lifter bores are also very accurate on the aftermarket blocks. Believe me it will be money well spent. I wont even fool around with stock blocks any more and its real hard to find the older 4 bolt main blocks that are the best.

Re: Hardblock?
Didn't know there is a bow tie block that matches a 273 Mopar.! Oh! The curse of trying to make 50 something old run with modern stuff.

Re: Hardblock?
I guess the real cure without buying a 3K block and getting thick walls, would be to sleeve a 318 to 273 bore size

Re: Hardblock?
I believe a Dart SHP block is less than $2000. There is also the money you will spend on the stock block you will not have to spend on the after market block. Filling, cleaning, checking... So that cost can be deducted off the price of an after market block also.
