I would have also gone with an old rebuilt truck axle on mine, but it's so narrow that there wasn't a donor I could use, and cutting/welding an I beam was not something I wanted. Hope you have better performance with the 292-.488" cam than I did. After a few months I got tired of it, and just changed mine out. Had problems with those aluminum heads I bought, and decided while it was down I went to the Isky 270 mega cam. 270 degree, .465" lift, and 108 LSA. Amazing cam that pulls hard now from right off idle to 6,000! Love the little details on your suspension! I went black on my front calipers also. Fancy colors don't look right on an old gasser theme!
