Since these Pistons are most likely going to be replaced, I am using them to teach myself where and how to measure them.

The Block needs extra cast flashing and the sharp edges bumped/removed, so that this procedure will prevent cracks in the future, where using a 3" round soft metal wheel in a drill, using slow speed to remove the paint. I can't depend on some shops to go out of their way in order to perform over and beyond their call of duty to remove casting flaws, we did the same on my Th 400, so we are good at it, trust us. I elected to service the Block and we have pulled the freeze plugs, only. On the exterior of the block, we removed most of the paint. We will clean the Block tomorrow with Dawn soap and a soft brush, in order that we may obtain our own set of gauge readings and precise measurements, ones that I can record in my own book, as I have been doing for the last ten years.

For example, look what happened when I brought the Heads to the shop and the machinist said that he would cut the exhaust seat bosses back to the proper size, then changed his mind and just installed a better seal over them.

When this Block goes to the shop, I will ask him to Magnaflux it and depending and depending of the outcome and if the Block is usable, we will let the shop go to work on it. I would have the Cam Bearings removed, inspect the Cam and Crank alignment in the Block, shave the Deck, and whatever they recommend.

I will bring the Pistons in on their Rods, along with the Cam and Crank to be inspected.

Once I get that report/information from them, then I will post the prognosis and we can talk about it from there.

Thank you all for your help, just to recap, this is either going to be a light build or if it needs to be Bored over, I just as well make it into a stroker SD clone. I will let the same shop build it as long as I get a warrantee for one to three years, if they will. It will come home as a short Block in a Bag. I have no doubt that I can build a motor, just not this one. It is one (1967 428 ci "special equipment" HO YK code) of 1035 ever made.

Ok now it sounds like you are definitely on right track. Thanks that answer allot of questions.

No, thank you.

Plenty to do yet, finding a reputable builder for this motor, I already got beaten by the Head Machinist. I am very Leary of people that claim one thing and do another; I hope I find the best for the job and that he takes pride in it. Then the decision of the parts, this job is in the best direction, but far from over.

If and when you finally resolve yourself to the fact that it needs to be bored and new pistons. 99% of doubt when it comes to a machine shop quality of work will come from choice of parts. You mentioned if it comes to that, you highly considering going with a stroker kit. If you want to eliminate 99.90 % of a questionable machine stops ability. By supply everything yourself. Long long a go, I realize this and would never have them supply anything. I just want to give you something to think about.

Here’s just part of the process lets say..ok it has to be bored and new pistons installed, ok now you get into the process, those piston pins are press fit, also those rods will need to be re-sized and new rods bolts. Most likely machine shop will require that So if the new pistons require press fit pin, vs full floated piston. In oder to do press fit pistons, what the do is heat the small end of the rod.

But here’s the thing thats a process that has long been eliminated with using full floated pistons. Kind of old school doing press fit.

So anyway The bottom line, is this buy a complete stroker kit. Comes with everything Rings, bearing, rods, balanced, all gaskets, rear main seal, the whole 9 yards. Sell your crank, so it needs to be turned -010 ( what ever) ok when it comes to using stock rods, I don’t care if they’ve been re-sized and new rods bolts. You are taking one hell of a chance, he’s why, oh motor all done, in car and everything great your happer then a pig in chit. But one day your out with car taking it though gears, then all of the sudden, rod lets go, for what every reason Guess what now you’ve destroyed the whole motor, specially if it windows the block.

The thing about stock rods is this, whats the history of those rods, with weather recondition or not how much fatigue have they suffered. Because it was over heated and donation the kind of donation you or previous owner of that motor has never heard, its like running round with a grenade with the Pin out, oh recondition they look pretty. You think your Golden.

Because it was overheated and experienced detonation, the kind of detonation that you or the previous owner of that motor has never heard, it's like running round with a grenade with the Pin out, oh recondition, they look pretty. You think you're Golden.

My original plan, If the parts that I have are "ok" and I can reuse them for street use, then, for originality's sake, I was thinking of trying, selling this motor to the person who needs it for their concourse restoration and is willing to pay out the arr for it.

Use the proceeds and buy a monster motor, shop till I drop.

I am not so sure of the value that this motor adds to my vehicle.

What kind of price could I be expecting, my guess with the Tri-power Rochester carbs. being true GTO and the intake being numbers correct, asking for $25 k?

What have I got to lose, I won't even run it, sell as is, just rebuilt by such and such here is the receipt and their guarantee...

I need to address this question while I am at it, please give me your thoughts on the matter, as truthfully as you can, "you own a 1967 GTO, Firebird, Big car and it is in concourse condition and this motor is perfect for your car VIN: 1967 YK code 428 ci HO Tri-power, you've upgraded from the Quadrajet. What are you willing to pay for this motor, if it increases the value of your vehicle from 100k with the period correct story to concourse matching code, correct now the market price is $ 250 K - $ 300k?

P.S. That Butler Kit has the Stroker kit includes the 455 Crank, I believe.

The above question is Hypothetical, but I need to get a real value, so I can benefit best.

My vehicle, by VIN. had the 403 ci Olds Engine in it from the factory.

When I get to that point of progress, I will see what Butler has to offer and we can tailor the kit to whatever from there. I like the Pistons with the Black stuff on the Skirts. I will be shopping for the part prices that Butler is offering through other companies' prices and products too. At least when I see Butlers parts it will tell me everything down to the Bolts.

P.S. I would go for the snap ring myself, unless press fit is better?
