Ok, it has been discussed and the final decision has been made, I'm going to put a small block v8, a newer 3spd, and a late model rearend in my '53 chevy, but the first thing I have to know is how much of the firewall supports do you cut out for the v8 motor? Second, do you still use the rest of the lower part of the support, and reinforce it to the firewall? Third, can you use the original tranny crossmember for this swap or do you have to cut it out and make a new one? In any event I hope it all goes well and be the best move I could make. Thanks for all your help and support.
