I have an inline 6 out of a 63 chevy biscayne. I think its a 230 but not sure. As far as I can tell the casting number is 3877178 GM 42. Is this a 230 and is there an adaptor so you can mount a 53 235 bellhousing to it so I can keep my original driveline? Thanks in advance for any help. Oh my car is a 53 belair. My 235 is dead!
