Hello,

I'm from Thailand.
I'm finding a 472 or 500 to put into my 78 Fleetwood brougham.
Today I went to see a 472 at my friend's place.
He have told that it has been remove from a 74 Fleetwood brougham which should be a low compression one. As I look at it the Block casting number is 1486238 which only use in a 472 from 68-69. So lucky me it is a high compression version!!
However the engine wasn't properly kept, some water went to the intake manifold cause the piston to stuck.
I think it might need a full overhaule with oversize pistons and rings.

So when it came to this point, I'm thinking about stroke it to 500.
I think i need a 500 crank, 500 piston and ring.
Could this be possible?

As far as I know 500 and 472 start from 70 use the Block with #1485200
But the 68-69 use the one with #1486238
It mean there is no 500 came from the factory with #1486238
Is there any differences between these 2 blocks?

Sorry for take you guy quite a long time to read.
also sorry about my english too.

Have a good day.
;)

There might be a need to clearance the older block for the longer stroke. Check with MTS on details & parts.
