413 info needed

[420willys]

i am getting a low mile 413 and 727 tranney ( 42.000 miles ) from a 72 dump truck ( w-300 ), what type of power am i looking at, i was going to put a 454 in my rockwell buggy but the 413 is only costing me 200.00 dollars so i figured i would get big block power cheap.

are there any down sides to the 413 and the 727 combo i know the 727 is a good strong tranney but what about the motor for my use, thanks jason.

Horrible choice of motors. Impossable to get parts for. You have to use a cluster fuck of all kids of different parts in order to make it work. Put in on a pallet and send it to me.

But ya, they have decent power, but as I said, difficult to find exact parts for. I have a 65. The early 70's HD ones are awesome, but those mostly only came in winabegos.

I dont knwo the exact power specs out of th emotor.

well maybe i will ask about the camper one he has and save this one for extra parts. is there any way to make this into a 440, i have heard about this type of build but i dont know the dark side of mopar power yet, jason.

They aren't bad, but i would try to find a 440. The 413 is just a 440 with a smaller bore. I remember this discussion the guy asked the same question
Here is Richard Erhenberg from MOPAR ACTIONS response,
The 413 was the first Chrysler "RB" (raised-deck B-block) engine; it came out in 1959. Eventually it was replaced by increased-bore-size versions for passenger car use, with displacements of 426 and 440 cubic inches. But, for reasons of maximum durability and cooling, the H.D. truck versions stayed at 413 cubes for many years.
There's absolutely nothing wrong with this engine, but there's also no particular reason to use it. It weighs basically the same as a 440, and you're giving up 27 cubes. And, no, it can't be bored to 440 cubes - at least without weakening the cylinder walls significantly. And, as we've tried to hammer home repeatedly, having strong, straight, and round cylinder walls, that the rings can successfully seal against, will make more HP than having another few inches of displacement - every time! The maximum recommended overbore for virtually all Mopar V-8s is 0.040", but if the bores will not clean up at 0.020" - stop!
Even if you decide to build a 440 instead, you can still use the rods and forged-steel crank from the 413.
