Has anyone ever put a Hydraulic roller cam in a 292? I haven't found any cam companies that show a hydraulic roller core for this engine. I would like to try this in a street motor with lots of lift and short duration.
any thoughts or previous experience?

Any cam company that has or offers a solid roller for these engines can supply a hydraulic roller, there made from the same billet. Its been done quite a few times with guys with 250's. Its the rest of the components that are a little tricky to source. Its also been discussed here in the past, just use the search button to find more info on the subject.

If you can get your hands on a set-up for the 250 you can use it in the 292.Just the fuel pump lobe will not work.You would need to run a Elec. pump.

Thanx guys. I forgot to set the search parameters to inlude the old posts. Still seems that there is a lack of personal experience in actually doing this. If I do it I'll post all the part numbers and required machining etc.
The 250 cam option would make the decision to relocate the motor mount easy.

The cam and lifters are the easy parts to figure out, but a lot of the other items required have to be fabricated or modified from other engines. Since the inline 6 never came from the factory with this setup, or been produced commercially in the aftermarket, there is no standard to follow and you can only adapt components from similar engines to get you there, but it has been done successfully and works well.

Chev SBC roller lifters with Olds 455 tie bars work on the 153's so they should work on the 194-292's

Is the oil delivery waist in the same place for Olds as SBC?
If yes, the entire Olds roller assembly may work if it's for the .842" small tappet engines (not the Toronado 425, etc. with the .921" tappets and 39° bank angle).

Panic, the lifters aren't the problem, its the rest of the setup that has to be sourced from other places or made from scratch to complete the puzzle that is the challenge.

I do not know if Crower still has the blanks, but they made hydraulic and solid roller cams for 292s in the past. It might worth a call.

Yes,Crower has them and Isky has the ability to make them also. Crane can as well.

I have never got any cam maker to give me the time of day when asking about Hydraullic roller lifters for a chevy 6 cylinder-- trying to get them to put other (olds) tie bars on sbc lifters.
if any one knows who will----or a contact - past a "gate keeper" please post. The owner of comp cams is just Too Damn Important--he's got to hang out at the golf corse--NOT THE PLANT!

Hydraulic roller lifters made by these cam companies aren't designed to be used with link bars like a solid roller lifter...thats the problem.

Mike Kirby at Sissell's Automotive got a solid roller cam for my engine from Crower. I don't know if they have a hydraulic set up.

Kirby had a few sets of prototype hydraulic roller lifters made a few years ago. But at this time, no cam company makes a hydraulic roller lifter for these engines as a production item, and has no interest to. While these engines might seem to be the greatest thing to us, it really isn't to them, and they have no desire to persue this type of product. So that only leaves it to ourselves to do it. I also saw on another forum that Cloyes as of now is discontinuing its double roller timing sets for the Slant 6 Chrysler, which is every bit as large in the inline community as the modern Chevy 250's and 292's. The Slant 6 forum arranged a group buy of timing sets and bought almost 100 sets at one time. This still wasn't enough to interest Cloyes to continue making them. Other companies unfortunately think the same way and will likely drop their inline oriented products as well before long if we don't try to make a difference.

That does Not Jive --The sbc chevy hydro roller has tie bars-just like the solids, and if SBC parts fit--then its doable--its just the oil line up hole of the olds lifters are in the wrong place , I havent heard anyone say the sbc oil lineup holes are not ok, The only real problem would then be getting a shop that would reinstall the rivets that hold the tie bars since we cannot get a manufacturer to put the olds tie bars on the chevy lifters.

Thats good that Comp is finally making them, they weren't offered with the link bars when I started this roller billet project several years ago, only with the OEM style dog bone connectors. There are some Chinese lifters out there that I knew about that had that design, but was leary of the quality.

Hey cnc --not sure you understood, crane sells links by themselves,, you still got to find some company that will put the links on SBC .050 taller hydro roller lifters, and always run into a brick wall of - NO REPLY..........

Not all of the roller lifters have the link bars bradded or riveted together. Some brands are threaded on with their pivot tab. The FTF has actually changed link bars on one of his Ford inlines that were assembled with this method. You might get lucky and find a company that still uses this method of assembly.
