    Got a bit more done today. K frame is now officially converted from 1967 slant sux to 1969 V8. The RH forward framerail repair is trimmed to exact size, and holes located for the overflow bracket mount. Will be tack welding 1/4-20 nuts to the backside of the repair piece before final installation.

      RH rail looked like this before I started the repair. Pic is of the LH one but both were crudely bent down

        Did the wiring for the electric washer setup in place of the manual foot pump which didnt work anyways. Going to have it route with the high beam switch behind the kick panel. Car is staying 2 speed wiper, but I think this will be a cool plug n play mod. Wires are wrapped in the non sticky vinyl wrap like the factory would have done.

          Going to mod the torsion bar crossmember and make a trans mount for the O/D trans before I put the floor pan in. Got the block mocked up for this. When I took the 318 short block apart the #2 and #4 mains were shot, crank was trashed, plus it was already .020" under. My buddy who gave me the "free eighteen" , sold me a forged 340 crank fresh cut .010" on the mains and .020" on the rods for $100. Damn near a gift. I will be taking the rotating assembly to my machinest to get it balanced. Then when I'm done mocking up the trans mount, I will pull the block back out and take it to him for hot tanking, boring, and decking.

            A bit on the torsion bar crossmember butchery. The strap I am making is the same thickness as the crossmember. Once its burned in, I would like to double strap it on the inside, cut the excess off below it, and grind the exterior side smooth. Then I will locate the additional holes and weld in the tube spacers for the crossmember mount bolts. Between all this, additional welds holding it to the floorpan, and a heavy duty trans mount bolted in, this should be plenty strong. Was a lot of work tweaking and bending this stuff to make it fit.

            Tech tip if you use your vise with the jaws open between 1/8"-1/4" you can feed the metal in and make slight bends every 1/8" or so and get a decent radius. That's exactly what I did. Also note, I am leaving part of the right angle edge at the front side of the crossmember all the way around. Really no need to cut that all the way out. Leaving it makes the crossmember stronger than cutting it all out, and making the whole thing a flat strap. And the gratuitous final pic of the scrap headed for the scrap trailer.

              Got a bit ambitious tonight. I just needed to get it welded in, and get the excess part of the crossmember cut out. I got a fair bit of grinding to do tomorrow, and a little bit of welding touch up to do here and there.

                Nice work. Doing it out in the open like that is the way to go. I may abandon my plans for same as the cross member is installed and the new AMD floor pan is in. I am worried about butchering the cross member. At least if it were out in the open, I could buy another if need be. Keep up the good work.

                  My plan was to leave it semi boxed in instead of just flat strapping it in like most of these are done. Doing most of this from inside the car with no floor pan installed is for sure the cats meow.

                  I feel leaving it semi boxed helps keep more of the strength than just cutting it all completely out and flat strapping it. The OD unit is pretty straight and isnt wider at the front where the crossmember mod is. This is one of the reasons I am leaving it semi boxed, plus it's easier to fabricate the strap that way. The drawing shown, the blue is the original crossmember, red is the added piece, the orange is the floor pan angle.

                  The bolt in crossmember will be made of 11 gage sheet steel, and be bolted with 4 bolts to the torsion bar crossmember. This should all be plenty strong.

                    Leaving it partially boxed is a great idea.......That is what I was planning. Cutting the loop right out didn't sit right with me.

                    It leaves room if you want to add an extra strap on top of the one that's there. This car will get upgraded subframe connectors from what's currently in there as well. Even if your floor is in, you can still carefully cut out the section of the floorpan where it overlaps the crossmember, modify the crossmember from inside the car, then weld the floor section back in. Carpet covers it up anyways.

                    Made 2 more weld passes at the front to beef it up more, and ground the rest down. Welded in 2 of the mount tube reinforcements, will weld up the other 2 when I build the mount. A little primer, and onto the next job. Getting that trans under there, and temp bolted in.

                      Sweet....Looks like it could have bees done at the factory. You should reproduce a kit with the cross member and trans support. Bet they'd move quick.

                      Would be a great idea, but it was a lot of fiddling around to get it just right before burning it in. I suppose they are all a little bit different. I left a roadmap for anybody wanting to duplicate though.

                        Done for the night, but wanted to slide that trans under there. Fortunately for me it lines up with my chain hoist and theres no floor in the car. Easy to lift it into place for mock up. That OD unit is effing big!!!

                            Well I did a little caliper measuring and also feeler fage and straight edge measured the TDC of the old pistons before removal and they were .080" in the hole at TDC. The new ones are KB167s at current deck height if my math is correct they will be .009" in the hole at TDC. The block will be surfaced probably .004" -.005" to clean up the gasket surfaces. The CR calculator I used puts this .030 overbore 318 with the 302s and felpro permatorque gaskets at 9.33-1 CR . Unless I decide on thinner steel shim headgaskets. Should be just fine. I need to do a CC check on the heads to get an exact number, but it should be close.

                            Got the trans up and in. Tailshaft blocked up. Chassis has been leveled, and engine block and transmission set to 5° down. Industry standard is 3° to 5° on engine and trans angle. I figure after I build the mount to a 5° driveline angle, I can always shim it up to 3° pretty easy if i needed to. Looks like theres a few appendages on the trans that others have lopped off on their installs to make it fit the floor pan. I will be doing the same as well when the time comes. Mid 70s GM truck mount is installed. Got to get the bolt in crossmember fabbed up and installed. Chain hoist made it super easy with no floor in there lol.

                              looking good :thumbsup:
                              did you set the driveline angle off the carb pad? that should be pretty much level (for fuel in the carb bowls levelishness), the motor/trans will then be at an angle as they design in the level carb pad to allow for driveline angle.
                              if you set it off the crank' centreline ignore me :lol:

                              Hi Neil,

                              With chassis level front to back and side to side, and carb pad level. The angle finder on the front of the engine block on timing cover mating surface is at 3° pointing down at the trans. I wanted to bring it further down to 5° because should I need to shim the trans it's easier to go up with shims, than have it set at 3°, welded in, and have to go down. Heres where we were at before I lowered the back end to 5° . Carb level. driveline angle tipped down 3°.

                                  Working on that trans mount crossmembers. Built a template out of cardstock, transferred it to 14 gage steel sheet which is the same as the stock one. I think it turned out great. I have a bit more to go on it, but so far I am happy with the results. It's similar to the US cartool one, but not an exact copy. Theirs uses thicker steel, however once its boxed and welded its plenty strong. Part looks welded crooked, but that's the camera angle, its straight.

                                          I used unidirectional bonding strips on that one.
