Actually Mike some 360/390/410 (4.05 bore) blocks can be taken out to the 4.13 bore of the 428. These are uncommon however. There is no casting that is guaranteed to do so (you have to sonic check everything), but the mirror 105 truck blocks are more likely to be one of those. Several guys on the other forum are running them.

I agree that you would be much better off starting with a 390 to begin with. If this is going in a truck running on the pump it would actually be better to find a 2v version since you'll be replacing the intake and carb anyways. The 2v pistons will give you between 9.2-9.5:1 CR, which is what you want for a truck doing truck things, while the 4v flat top pistons net a 10.2-10.5:1 CR which is a bit too high unless you plan on putting a big cam in it. You could lower a 4v's CR a bit with custom head gaskets that are thicker than normal (Cometic makes some) for a cheap way of doing it, but this is going to throw off your quench. To do it right though you'd need the dished 2v pistons, or aftermarket pistons if you have to overbore.
FYI avoid the 1.66" compression height pistons for a hipo build, they will give you about 8.5:1 CR. If you go into a parts store and order some, these are likely what they will try to give you.

 

Bottom line, start with a 390 or 428 or spend a lot of money for a lot less performance.

 

Yeah, I know some will pass the sonic test. I was talking in general terms.
Several years ago I tore down a 390 that was already +.060". The cylinder walls were good, no ridge. It had always had a problem with what I felt was excessive blow by.
I toyed with the idea of taking it to +.080" (at the time I had a 428 crank laying around) so had the machine shop sonic test it. They came back and said that it shouldn't have gone to +.060"! The walls on two cylinders were already too thin. Shouldn't have gone past +.040".
At least now I knew the reason for the excessive blow by.

 

I don't know where you live but here in Calif we only have 91 octane at best. That has gotten $5.30 a gal every so often. Well, Ive had to run the highest octane since 1978 until 09 when I replaced the motor. The old motor was a 1967 390 2v car motor with 9.3cpr .030 over I could not run with any vacuum advance hooked up and timing at 0-2* BTDC at best along with the gas additive for unleaded gas this helped it from pinging some. My truck weight was 56.330lbs+1500lbs cab over camper. I dreamed of the wonderful day when, I could just buy cheaper 87-88 octane gas as any way my mileage was 8-10mpg. at 50-55 mph. Okay I the new build .030 390 105 block 428 crank 8.4compression ratio. I lightly worked the heads over, all ss valves, and so on. Any way the point I'm getting at. I no longer have a camper on it . This new build running regular gas is way faster the my old gas hog the needed high octane gas. So think how your going to be using your truck and are you going to be doing and long distance with havey loads cause you hate yourself for going to 9.3 or higher comp ratio when and if you have to run $4,$5 bucks a gal gas. just sayin some can do it just for a slow cruising rides..
