Competition Hmm B5.9 or B6.7 mods?

[Jeff H]

So is it really a 5. 9 or a 6. 7 in disgise. Makes me wonder if anyone has snuck a 6. 7 in the mod class?

 

[jwilliams3]

They are 5. 9's.



I could explain why I know this, but I might give away too much info. :-{}

Does anyone have any info on the 6. 7?

 

[Jeff H]

I have all day!

 

[Bpostel]

Jeff H, what kind of info do you have? Come on spill your guts :-laf

Wonder when they'll find there way into a Dodge? Suppose it's possible to get parts for these motors yet?

Wrong! 6. 7 = all new block!

We've got these in everything at work, the blocks are totally redesigned. They are a lot narrower than the 5. 9 and look way different!

We've had to change 3 head gaskets so far on these, one machine had 20 hrs

and the others less than 2. The head gaskets are laminated and oil leaks thru the middle of it. Can you say warrantee?

Well I'm just passin on from what I've heard. Right now don't know who to believe till we see some pics or spec information.
