    Ok, I just put a rebuilt 454 into my sub, and I am finding that the temp sender from the old engine doesnt fit the new engine. The sender is too small for the hole.
    Thru a little bit of research on this site, I found that the early(pre-80) heads have a larger port, and I think I found the Part # for the sender that will fit.
    BUT, will the larger sender work with the gauge in my "83? Is it going to be off all the time? If so, is there a way to correct that without replacing the gauge?
    I dont really want to drive the truck without a temp gauge.
    Also, what is the correct oil pressure on a 454?
    Thanks in advance!

    Use an NPT adapter. You probably have to go from 1/8" to 1/4" npt. They sell those at any hardware store. Also the temp sender is probably the same. Its not a big deal to change them out luckily.

    Correct oil pressure depends on alot of things. But rule of thumb is 10psi for every 1000 rpm (5000rpm = 50psi)

    All the gauges work the same way, senders are interchangeable short of the physical size problem you found. :)
