    Can anyone tell me what engine this is or what make? block casting number is 4006730-318-15 and the intake casting number is 3830941. Please help my friend got it in the back of a truck he got. It has a chevy firing order with the distributor in the rear but on the right side. Also the 2 center exhaust ports seem almost square but it looks like one corner was cut out? If you find it please tell me where because I have exhausted all my sources. Thank you? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

    Alright we looked at the other side of the block and it says 11-17-75 which would be the casting date. I found a bigblock (mopar) with that same number of numbers and the dashes in the same spot and it starts with 400 but it doesnt match the rest. The firing order is 18436572 just like a chevy right?

    Guess that's what I get for assuming it was a CHEVY motor
