2020年11月1日 · Above the water pump, it's stamped T0428TSD. I couldn't get to the casting date so it's either a 75 or 77 truck 454 from a C20 or C30. The block appears to have been originally orange and then painted blue at some point. With it being a Mark IV block and the size of the holes, is it LIKELY that it is a 4 bolt block? How good is the 361959 casting?

Best production 454 block for hi-po build? - Team Chevelle
2006年11月2日 · I have a couple questions about production 454 blocks, and which would be "best" to use as a high performance builder. I have an '87 454 2 bolt block that I can use for this application. How is the quality control of a later block such as my '87, compared to say a 70-71 454? I mean things like core shift, nickel content, etc.
