Oh boy! Another 413 food fight! I can talk about motorhome 413's because I've got one and built it nearly 30 years ago. Here's a short list of things I pitched when I got my motor home 413:
Heads got swappped for 440 items. Intake from Weiand. Couldn't use the cam or even the cam sprocket because the MH 413 version I had used a gear driven cam that turned backwards. Rockers and pushrods. Water pump and housing. Balancer. Oil pan. Distributor and drive gear. Pistons. Exhaust manifolds.
Even little nit-noid brackets and bolts didn't fit. In other words, I had to nearly buy a complete 440 just to get the parts to put the MH 413 into a car. And in the end... I had a 413... down on cubes from a 440. So... that's the deal. If I had to do it over again today... I'd go for a stroked 400. Just me.... The OP mentions his 413 is coming out of a car. He's still going to have to upgrade to 440 specs... and... it's still going to be a 413.
