I'm installing captains call on a 454 with 496 exhaust manifolds . I have run the 496 manifolds for a couple seasons now . My main question is connecting to the y -pipe / width of the y-pipe . I've searched a lot and most of the info I see is that all v8 y pipes are the same . I read on a sea Ray forum that the 496 y pipe was 3" wider but no part numbers . I bought a y pipe from a 2004 Baja boss 302 with 496's. What confuses me is the y-pipe is about 3" narrower than the outlets of my exhaust risers /elbows. I know I can probably make up that 1.5" difference on each side but I'm surprised I should have to . Searching around OSO I see that is common to use 3.5" soft wall exhaust hose to connect the y pipe oval to the captains call oval . Or I see IMCO makes an oval connector longer than stock .I didn't actually pull the engine or install the Y pipe yet I'm trying to get everything prepped for doing it before winter . Does anybody have any insite on this y pipe width thing ? Or pictures of 496 captains call setups . Thank you

Thank you for the picture . It makes more sense now. It looks like your Y pipe isn't quite as wide as your exhaust elbow to elbow width either . That makes me feel better that's just the way it is . Very clean engine and bilge !

That was taken earlier this year. It was a new build I did for a friend. Whipple 496 with forged internals in a 2001 Donzi 26ZX. Unfortunately it's back at my shop as the drive coupler blew during break in. So out with the engine. Again...

Where did that oil filter come from???

They used to be made by Wix.

That Kmart filter is a vintage unit I found on Ebay. As you can see in the pic I set it up with a remote mounted oil filter on the transom, so the factory oil filter mount is no longer used. I thought why not put a conversation piece on the engine. We get lots of laughs with that kmart filter. People see a whipple supercharged engine and a kmart filter and shake their heads.

87Mirage,

Too funny. Reminds me...

Years ago, I broke a rod in one of my 3.5cc two stroke model boat engines, and it punched right through the side of the crank case. Instead of scrapping it, I milled the hole to cleanup and made up a blocking plate to match that was held in place with two screws and aluminum-filled epoxy. The engine ran great for several season after that. But, just for laughs, I also drilled and tapped a blind hole in it, put a brass nipple in it, and ran a length of fuel tubing back through a bulkhead. It wasn't connected to anything and didn't do squat. Any time anybody noticed it and asked, I'd go "SHHHHHH!", and look around, acting like we were in the middle of a drug deal. It's amazing what some people will believe if they think it's some kind of speed secret.

Thanks. Brad.
