410 Swap

I may be able to get my hands on a 410 motor for my 73 F250 with a 360. Am I correct in assuming it will essentially bolt right in? Same mounts etc

Some early FE's were different. what year is the engine? I believe mainly it was 352's that had a different bolt pattern and a few other differences.

410, if it was born a 410, was '66-'67, so it had the later motor mount pattern. Same as the 360.

Check flywheel and balance. I'm not clear on that and can't search it out at the moment.

I’m told it’s a ‘66. I’ll need to look into more now that I know it’s a viable option

'66 should be fine. it was the first few years that were different.

Awesome.

The 410 uses a 428 crankshaft and harmonic balancer.
Those two parts are different from the other FE engines.
The crankshaft is externally balanced unlike the 360.

A 410 is a 390 with a 428 crankshaft and its own pistons.

Pickup 390 2V pistons are 410 pistons. Not difficult to get.

Sourcing a flywheel for a manual transmission is the hard part.

I have two sets of those covers. One set lived on a 352 I put together in high school, got transferred to the 390 that replaced it when I was in college, and now lives on the 390 4V in the 1971 fencing/plow pickup here on the ranch. The other set my dad had chromed and they are hanging on his shop wall. I still have, like you, an OEM 410 air cleaner lid too.

Dad had a 410 in his '74 F250 for a while and sold it to his cousin who put it in his '76 F150. But then again, I think dad's on his 7th engine in the pickup he bought brand new because he gets bored. Started life as a 360 (4x4), went bigger, smaller, auto to manual and back again a few times. He's had a 460 and C6 in it for about a decade now. He's going to be 78 and I don't think he'll be swapping again.

I bought mine off eBay, they looked new but I can't swear to it.
Not even a hint that they had ever been bolted on to anything, not even the tiniest mark from a lock washer.
I paid $300 for them.
The air cleaner is after market. I bought the Marauder 410 4V stickers are licensed reproductions.
I bought them off eBay too.
I found the 410 in Co Springs. It was rebuilt in 1972 and never started.
I'm very pleased with the way it runs.
