I took the SBC out of my '38 Chrysler to replace it with a Mopar 383 big block. On paper it looked like it would fit, and in real life it will, but it looks like the front crossmember will need modification, and I'm looking for advice on exactly how to modify it. Here are some pics: Its all the way back against the firewall- Water outlet is about an inch from the crossmember, and over it by 1" as well (1" tape there for reference)- This shows where I need to make space for the oil filter adapter (I'll put the filter remote); and how much I'll have to cut for the balancer/lower pulley, The x-member is like a big box of maybe 10ga steel measuring 6.5" front-to-back x 5.5" tall at its smallest point @ the center/front. Right now I'm thinking of making a cut for the pulley about 7" left-to-right, 2" down, and 2.75" front-to-back. It would be a half moon shape using a section of 7" heavy wall tube cut in half (and obviously a bit of flat stock) to box it. I'm thinking much smaller notches- also boxed- for the water outlet & oil pump. Am I on the right track?? Is there a better way?
