Looked at pics of the sweep pattern from when I put the t&d set up on. Not nearly as short as yours. I thought they were acceptable at the time but obviously not.
Thanks again.



I absolutely hate to beat a dead horse, but you are the perfect example of why Chrysler guys drive me nuts...and I say that in the most friendly manner I can type so please don't take this wrong.

I don't care what rockers you use, on what heads, big or small block I'd bet everything I have, and some stuff I don't have that I can walk through the pits at any mopar race and show you 85% of the engines have valve train issues. The number 1 clue is lash caps. The number 2 clue is you aren't using a kit from B3 racing engines or, you haven't milled the stands off and are using google offset shafts and stands.

If I don't see that, you have geometry issues. Do guys get away with it? Sure do. But it still doesn't make it correct.

Literally, every week on the web I see guys asking about lash caps and being told it's not the fix, and sure as hell someone comes along and tells them they've been using lash caps since before the council of Trent and there's nothing wrong with them (there isn't a thing wrong with lash caps I you arent using them to correct geometry...and what's sad is Harlan Sharp tells anyone who asks the lash cap is the fix for geometry and they are wrong) and not to worry because the sweep is centered.

You hope eventually when someone has an idea that is functional and economical it would catch on. Why I have to repeat myself virtually every week about contacting B3 and getting his help is beyond me. I've had people PM me and ask what kick back I get from diving business his way. The truth is I don't. I pay for his stuff. I use his stuff.

The moral of the story is you have caught an issue before it went into the toilet. Call Mike and let him help you. Ignore the people who tell you it's anything but geometry. I think you'll find Mike easy to deal with and his stuff works.

Fix your geometry and then don't worry about the valve train. As a side note, I've had guys call me and tell m after correcting geometry they had to lash the valve less often and the lash wasn't moving like it was before they fixed their geometry.

If it wasn't for this site, and Mike posting his stuff here several years ago, I wouldn't know about his stuff. Thankfully, he has the ability to ignore the nay sayers and just keeps moving forward.

Please keep us updated on what happens. Hopefully what you do will help someone else from having issues.



Not sure what this is all about. I thanked the gentlemen trying to help each time I replied and reading back through my post I don’t see where I once contradict or argued the advice offered.






You didn't contradict or argue, but I'm sure there are many out there who will. That was my point. Just like Mike said above, you did the best with what you know.

Back in the early 1980's when Edelbrock came out with springs that had 300 pounds of seat pressure at 2.00 installed height, virtually every cam grinder I talked to said their cams didn't need a spring like that and their "lobes" weren't parts breakers. It was considered a SIN to say you needed that much spring.

My point is is the same way today with rocker arms and geometry. I can't think of a single company who will tell you you must check and correct your geometry and the best "fix" is lash caps. It seems that anything else is considered criminal in the minds of the head manufacturers and rocker makers.

I've bitched for years (actually decades now) that companies like Indy and Trick Flow (no picking on either just using them as examples) still make their heads with the shaft position buil into the head. There are too many variables in rocker arms alone to make whatever position they use correct in every application and is probably wrong in most applications. Is it close enough for most? Evidently. But then you get wierd stuff like you are seeing.

So I wasn't picking on you. Just using your example to maybe help someone else who may stumble onto this thread.

B3racingengines.com is Mike web site. His email and phone number is posted there, as are a real good set of technical articles.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
