    Found a 454 possibly, a few ?\'s

    A friend called and said that he found a 454 but, had no idea how much its worth. Its out of a mid-70's 1 ton truck. He said that it started to rod knock a little but that's it. It has been sitting for 2 years. Would $500 for a complete engine, thats needs a rebuild, sound reasonable? Also, I have not seen the engine yet
    but, I want to make sure I don't get a 427, since they both share a 4.250" bore size. Is there any way by looking externally to differenciate(sp?) between a 427 and a 454? Or does any body know any block numbers or letters that would point me in the right direction to a 454. I plan to pull the heads and the pan to look at it closer but, did Chevrolet but a 4 bolt 427 in some of their heavy duty applications?

    I just want to protect myself so I don't get surprised with the wrong engine. What else could I do to avoid getting into a fight over money if I discover if the block is cracked after the fact?

    My friend works with this guy so it won't be like I would never be able to contact him again but, I would like to get a solid engine from the start.

    Sorry for all the questions but, time is running out for me and I need a 454 before the end of the month.
    Long story.

    Hell a 427 is somewhat rare. You may be able to turn around and sell it for a profit!

    The 427 tall deck is somewhat common although I've never seen one in a regular pick-up, mostly in 5 tons and such.

    If its got a rod knock, that probably means the crank is shot, and a core 454 crank runs anywhere from $150-300, so figure that in to your calculations. Best thing to do is get the casting # and check it out on mortec.com, then pull the pan and tap each rod cap with a ball pean hammer to see if it has a hollow sound. If it does, pull that rod cap and see how badly the crank is worn/grooved. If its grooved badly, its junk, and offer the guy less. Good luck, and be careful not to buy a pile of junk!!!
