Yes I have a sheet metal shop I work with that can laser cut and bend these if anyone is interested. I doubt they would be very expensive.

They come that way. They are the ones that come in the Comp Cams Ford spider kit. But, even with the notch they don’t have enough clearance to prevent the dog bone from lifting unless they are spaced off of the tops of the lifter bores.

Good info. I like your setup here. Seems to solve some of these issues.

Andrew-
Talking to Jim Lehart, he has at least 20 setups running- some with a significant amount of mileage on them- he's had no issues with them moving up and down. I'm thinking that if a better mousetrap can be made, make it... I think the dog bones would work better when fitted more like a Harley lifter cuff, but if the current design works (it does) maybe we're getting too far off course. Nothing wrong with the KISS design approach.

There's SBC retrofit trays derived from the LSx design that might also work... I'll take a look at these. 88958652 - VALVE LIFTER "THE QUICK CAM" GUIDE (TWO REQUIRED)
If the lifter spacing is right, they might work. |

I was going to PM you John but figured the information would be better posted here, if Jim doesn't mind. |

This is a photo from FB in which the LS lifters were used with success. |

Just a suggestion that some of the inferences are that the oil filters may not be fine enough to keep fine materials out of the oil, and cause ticking lifters. 10 microns is not attainable with a conventional oil filter. I'll just leave it there, so I don't stir up the anti by pass oil filter groups. It may or may not be a factor, just throwing it out there that fine particulate could also be a factor that is causing some of the ticking problems. I have roller lifters in both my LS2, and my 6.5 diesel equipped with by pass oil filters, and have never had any ticking with 140,000 miles on the LS2 or 270,000 miles on the 6.5 diesel. My 3.1 V6 in my 118,000 mile 99 GP does not have a by pass filter, and I do occasionally have lifter ticking with it. It will get a by pass filter as soon as the weather warms up a little bit. |

RH68 Thanks for the pics showing notching of the dog bones. I like your idea of boosting them up a little if that keeps them from lifting.
I'm not a fan of the dog bone cuffs idea. It just seems to me if the lifters were to catch the cuff during upward travel it would be absolute carnage. However I do like the idea of a taller dog bone. |

I understand Jim is dealing with some health issues. Please convey to him that the Pontiac community appreciates this information he has shared as well as all he has done for the hobby. I think it is safe to say we all wish him the best.

Thanks John and Jim for your posts and contributions. Hoping all is well with Jim and I had no idea he was dealing with a health situation or I wouldn’t have asked about the retrofit details.
There will soon be 21 set-ups using this modification. |

Randy, I looked at that picture and I just don’t get it

So since you say you will be milling a 45 on these plates, does that mean the long edges of the plate will rest against the flat on one side of each lifter? Is the idea that you only need the guide against one flat, not both like the dog bones do?
