1972 Big Block engine for trade - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1972 LS-3 402 big block from a Chevelle that I would like to trade for a complete 1972 big block truck engine. The suffix code is CTB with a casting number 3999290 and date of L 13 71. I am looking for a truck engine with the same casting number and a TKA or TKB suffix code.

The heads that come with it are complete 454 open chamber heads, some of the best GM ever built with casting numbers 336781 and both dated D 17 74 You can check out the info on them at www.mortec.com

If I cannot find someone for a trade, I may be open to selling it outright.
