It sounds like a Chevy block. There should be casting numbers on the heads.
You can cross ref. those numbers and find out what engine it is. The block
also should have casting numbers.

Hi,

I have recently bought a 1968 Lazy Days, 43' aluminum hull
houseboat. I haven't been able to learn what year or size
the engine is. What I do know is that it's a Crusader, Charger
series, 250 h.p. V8, distributor in the rear, serial # 13050. A
single engine and it's an inboard, which a friend told me is
very rare on this type boat. From that info, is there a way to
find out what type and size engine it is?

Thanks for any help!
David
