BBC swap

[Gimmie1965]

I'll apologize first off if the is a thread somewhere that already covers this. The v6 took a dump on me yesterday while I was loading it to haul some trash to the dump. Needless to say the bbc swap came sooner than expected. First off I want to say this is not my first swap into a 65 gmc. Bought my first 65 when I 16 in high school. It was a 65 gmc shortbed with 230 and 3 on the tree. I pulled UT out and dropped a 350 in it. Same mounts flywheel clutch bellhousing no problem. So I get the v6 pulled out of this one and drop in the bbc. Start off I pulled sbc mount out of a 69 at the u pull it here. I figure for 5 bucks I'll try them. I put them in the holes closer to the cab like what I've seen others have done here. Since the gmc v6 and chevy bellhousing are different I found a 68 bell. I get the BBC dropped in and have the motor mount close to being lined and look and the bell is close to about a 1-11/4 away. Now as I said I've done this before with a sbc and everything fell right into place. I measured the v6 bell from where it bolts to the block back to the crewmember pads on the bell and it's 61/2 in. The chevy bell is 51/2. So long story short is there a difference in the 63-67 bells to the 68-72 bells as far as where the rear motor mount are located. I'll take some pics so you can tell a little bit better what I'm talking about
