    Trying to ID rebuilders tag found on BBC. Any info would be greatly appreciated.

    Starts out like this, BBC 454 from a motor home, stamped is CSS which comes back as a 72 vet 270hp 390tq, but found on the left side of the block is a rebuilders tag, that I am wanting to decode somehow to see just what has been done to engine other than what is stated on the tag. Here is what I have Block Casting 361959 Head Casting 14081045 (open chamber Oval Port) intake casting 340218. What I have been able to dig up so far, shows it should be a dished piston truck engine rebuild, but when I look into the cylinder bore(bore scope) I see flat top pistons with small valve reliefs. I really didn't want to take engine all the way apart as its a good running(dry. No leaks) engine. I am planning a cam change and maybe intake depending on what I can find out about the rebuild. Thanks for any help. Curt

    That tag is a GM tag , it denotes a GM 454 Long block replacement engine .

    Basically a GM over the counter replacement engine, I've used many with no issues to speak of.

    361959 is a desirable block to start with , probably 2 bolt , but no worries there .

    14081045 is a small oval (Peanut) head , that engine with a small cam and those heads would be a tire frying beast .

    Don't get sucked into more cylinder head / more cam / etc .....

    If you want a good all around performer that'll cruise all day on pump gas , you have it.

    Thank you for your information. I plan to just bump the cam a bit and good intake and headers. Again thanks for your help. Curt

    Be sure to check retainer to guide clearance with the cam you choose , from GM those heads will be all over the place so check them all.

    Good luck with the project.
