Title: I need help identifying an engine
Post by: LagginWaggin on November 27, 2017, 12:26:45 AM

So I bought a 403 or so I thought, it has all the casting numbers for a 403 but when I got to looking I realised it had 455 heads, then when I went to buy parts for it (oil filter, oil pan gasket, valve cover gaskets and a distributor) only 455 parts fit. So what do i actually have?
Casting numbers: 557265
Vin number: 37F119668
