Re: big block in a 2wd 67
67 & 68 are the same- he will need to buy the big block towers and that should be it, however it would be much easier to let me haul off that big old motor so he won't have to worry about it

Re: big block in a 2wd 67
Yeah, the 67 frames don't have the top flange of the frame narrowed like the 68s and up. See my build thread, and you'll see pics of me trying to get my motor stands bolt holes to line up.

Re: big block in a 2wd 67
Why not just bolt it in? If he is running headers it should be no big deal anyway. Ive had a small block & a big block bolted in my truck with big towers. Have done it both ways with small block towers too in a later truck too...

Re: big block in a 2wd 67
Been helping a friend of mine do the same thing to his 67 sw shortbed. http://67-72chevytrucks.com/vboard/s...d.php?t=223504 The tops of the framerails needed to be cut back a little here & a lot there. 68-71 BB stands are "clearanced" from the factory with the dimple on the top for the exhaust manifold. The 72 BB stands are altogether different. 73+ stands are the same for BB or SB. Tell him to save himself a lot of work and look for a set of 72 BB frame stands(insert flame here). The 68-71 BB stands are more readily available but the motor mounts are A LOT more money. I don't have any personal experience with the 73+ stands but I have heard that they go in with a drill and will allow you to run the later clamshell style mounts as the 72 BB stands. My friend attempted to use(albeit DID use) SBC stands and had a nightmare trying to get headers to fit. After a lot of cutting, welding, cussing and crying(not to mention pulling the motor quite a few times!!!), he got them to work(but he did put a stout chain on it too just incase the sh!t hit the fan. He also is running the later long waterpump and has issue's putting a belt on the crank pulley.

Re: big block in a 2wd 67
I went the cheap route when I replaced the motor mounts on my 69. I bought 6cyl mounts @$9 & ground a little of the side material off. I did have to grind a little of the extra material off the sides to clear a spot of casting on the block but it saved me big bucks...
