    Hilborn Fuel injection - small block Mopar

    I believe Hilborn closed their doors recently... for good.

    Ship hit bridge, bridge crashes into water

    I looked even weaker when it first opened. See the pic in post#16. I don't think I would like that bridge much either.

    the USS New Jersey battle ship.

    I did not read all of DC 340's post but what I gleaned. From the article, was.... They were firing a 2700lb shell with powder specifically for a 1900 lb shell, and marked "do not use with 2700 lb shell" Also, apparently the rammer (for the shell and powder bags) was over extended. During...

    Figuring out how much heads have been cut?

    Again without pulling the heads to actually see, and measure, what you have, there really isn't any way to really KNOW what you have. As I said above, Trw made 8 to 1, 9 to 1 and 10 to 1 flattops (the ten to one's had valve reliefs, which yours dont) and domed "11.5 " to one. It MAY have 9 to 1...

    Figuring out how much heads have been cut?

    Later 440s (76-up?) (Typical motor home 440) had pistons around .150 in the hole. Whatever they might have been claimed to be by Mopar, they were really on either side of 7.5 to one.

    Figuring out how much heads have been cut?

    I'm NOT familiar much with what is available in cast pistons. But in my old trw catalog there were at least four different forged pistons for a 440. There were the Sixpack replacements that were somewhere around .020 down. There was the domed 2295 (11.5 to one,Hah!) that were about .050 down...

    Figuring out how much heads have been cut?

    Somebody might have milled the crap out of the 915s, trying to get some compression. A 69 motor shouldn't have what looks like 1/8" deck. If it's got 8 to 1 replacement pistons in it, it would explain the swap to 915s for a little grunt. From the bottom, they look like cast replacement pistons.

    Figuring out how much heads have been cut?

    That's the way I always check bbm heads. No way to know how much the block has been decked while in the car, that I know of. If the heads were off, and IF you knew the compression height of the pistons, actual deck height could be compared to calculated dh.

    Will 383 pistons work in a 426 Wedge ?

    You have discovered the major problem with a 413/426W......piston availability. Even 383 stock replacements tend to have slightly too much compression for modern gas, and the forged selection is getting pretty thin for a 383 too. But I tend to agree... if your gonna spend custom piston money...

    452 heads on a 1965 Wedge ?

    Details matter. For giggles, for a .030 over 426W 90 cc head, .039 head gasket, .050 deck...... less than 9 to one. 88cc head, .025 head gasket, 010 deck....... slightly over 10 to one. 75cc head, 039 hg,.050 deck...... 10.16 to one. 75cc head, .025 hg,. 010 deck......11.58 to one. All above...

    Will 383 pistons work in a 426 Wedge ?

    Racetec/Autotec will make one change to a shelf piston for free. Too bad they don't even list a forged piston for a 383. If you want a piston for a Ford flathead....or 312 y-block, .... or a pinto.... THAT they've got. And literally a thousand varieties of Chevy pistons.

    Will 383 pistons work in a 426 Wedge ?

    No stroker kits for a 426W? Then look for a forged 383 piston around 1.88 c.h. (or less) 383 flattop at 1.88 might be a bit too much compression for pump gas. At $1000 for a cast or hyper for a 426, I'd definitely start looking for an alternate route.

    452 heads on a 1965 Wedge ?

    I can do that for you... but you would be better off learning to do it yourself. I always recommend the calculators at Wallace racing, they work easily and well for me... and he has about a hundred of em. Trouble is, for ACCURATE results, ACCURATE measurements are required. (And I would assume...

    Will 383 pistons work in a 426 Wedge ?

    GTX John is dead on. It CAN be done, and work well...... with .100 longer Hemi rods. But buying a set of hemi rods to use a shelf piston would be a bunch more money than buying a set of pistons FOR the 426W, even if you have to buy custom. Edit: icon 1.912 383 pistons and molnar .100 long hemi...

    Will 383 pistons work in a 426 Wedge ?

    2.083 would theoretically be a zero deck piston in a blueprinted 10.725 block (413, 426, 440) So, It depends on the compression height of the 383 piston. Anything over 2.00 might be serviceable, depending on compression ratio desired. A domed 383 might even work, if the ch is too low. Time to...
