Big blocks, mounts and headers
Ok, so looking into doing a big block swap into the '69 half ton 2wd.
Seems like there are a few options. I've seen (think it was TXFireFighter?) had a thread about using 67-71 big block motor mount perches with small block mounts. Looks to give a good amount of clearance for headers but I don't think he showed any headers installed after bolting in the motor. For about the same money you can get the tubular perches (from parts online or something?). I saw a thread here where someone else had used these mounts with a big block. My main concerns are: #1 Motor position. I'd like room for big valve covers and not have them hitting the firewall. #2 Header clearance. I'm looking to run 2" primaries. I don't mind trimming the frame a bit but I'd like them to clear the mounts/perches. What have you guys done with yours? Please post your mounts and what headers you're running. Pictures are a plus, we all love pictures. |
