On the BD/BG series, where is the block split between the 240/264/280/308 engines? They aren't all based on the same block, are they???

Not sure. Called Ernie Bisio with your question, he didn't know either.

He referred me to a guy who hasn't called back yet.

Do you think we could get Allan in here?

Glad to see we this thread started. Maybe it will turn into a seperate frum in the future. I have a BD240 in my '58 A-120 and I also have the repair manuals for the 240 (as well as the rest of the truck). I'll be glad to share any info.

I have a Holley 1barrel carb on my BG241.

I was wondering if any of you have found better options in that department, as I am not a Holley carb fan. Of course if tuning the Holley for better performance is possible, I am all ears on that subject as well.

I would like to use a Rochester 2GC, or the like if making this Holley perform cannot be done. I can machine anything to make it fit, so that isn't an issue.

Okay, I guess I will take my morphodite truck and hide in the corner!!

Andy,

Don't hide in the durn corner......

Nobody objected, and perhaps I was a bit hasty.

Bring up whatever you wish, as long as it's an inline-6

John, I'm not hip to the 2GC. The Holley 1904 pretty much is what it is AFAICT. Mark P. highly recommends checking out the Rochester Monojet as used on the Chubbi inline 6's, I dunno

I would love to chop up a manifold, and put a brace of polished 1bbl carbs (3 to be exact) on this engine.

Chrome the valve cover and side cover(s), and give the engine a nice fresh coat of the correct color of IH paint (another thing that I cannot find any data on ).

I really like I-6's, always have. They have a certain character about them that v-8's lack in my book. That, and given that IHC 6's have the same kind of grunt as Diesels.... it's only logical that I should love them.

Any chance you could get Mark P. into this discussion group? I think he would add a great deal to it

Ok,

The engine names are another sticky spot with me. I know the following ones.

SD = Silver Diamond

RD = Red Diamond (would love one of those!!!)

BD = Black Diamond (another favorite)

GRD = Green Diamond

BG =

That is one that escapes me, what does it mean? I know there are other ones I have missed, so chime in with your knowledge guys, and PICS of the engines if you have them.

Keep on Binderin',

I looked in the Hollander Manual (the interchange manual used in wrecking yards) and found some info on the 220/240/264/308 blocks. There is some confusion, but here is what they have.

#568- BD220,240; BG220,241; SD220, 240
#569- BD264, BG265
#570- BD269
#571- BD282, 308

That covers the SD, BD, BG 6 cylinder engines. The # is the interchange. When you look it up, it tells you what will bolt in as a replacement. When I looked the individual # up it pretty much showed the interchange as what you see beside the #. There was some mention of having to use the oil pump and filter assy for each engine if you change displacements.

BG- Blue-Grey.

As was explained to the digest a couple years ago by Hofs (I think...), They were running out of primary colors, and Fushia Diamond just wouldn't cut it
