My son in law gave me a BBC, not sure what I have. On the bell housing it has the casting #3969854, on the front passenger side it has stamped T0610CLB - 11C182886. From what I have found it's a 396 or a 402? Not sure, can you help me out? Want to build it for my 18' avenger jet and ditch my 455 (for sale/trade in the spam section). What ever it is, I want to build a nice "daily driver or rat rod" if you will. Not racing it, but a nice pump fuel running, give someone something to think about, kids can drive it, runner. I'm glassing in new stringers so now's the time to do it!
Any advice would be great!
