Roller cam ???

[skipxt4]

I'm toying with the idea, of treating my 409, to a Solid Roller Cam, for summer. I've read about the problems, of the lifters not getting enough oil at idle. Isky has Red Zone lifters. Is that a solution? I'm not looking for a .600 lift cam, and not planning, on going over 6000 RPM. Also, I can't see driving more than 300-400 miles in the Summer month's. How many of you guys, run Solid Roller Cam's, on the street? Can they live? Good idea or not? Thanks in advance.

Skip.You don't really need a solid roller cam,just find a mild hyd.roller cam run solid roller liFters on it and stay with the much milder valve springs.The ''Red Zone'' liFters can be an option,but are very expensive for what you're trying to do.Howards Cams did make a ''Street''solid roller lifter that would satisfy your needs since they are made to use a liGhter spring load,making lower loads on the valve train. I don't think the roller cam is a bad idea.I also think that most of the roller lifter failures are caused largly by the heavy spring pressures needed for the large lift,wide duration cams that most people use together.A mild hyd.roller cam in the 230,intake,236 ex.range in your 474 would suit you just fine.Comp makes just such a grind.

What Don said!! I’ve got a hyd. roller in my 70 Vette 350 and it sounds almost like solid lifters! Iv revved it to 6500 several times!

One of my Pontiac buddies has had Crower single hole oil go out and and Isky bushed on his 505 street driven motor. Current went back to Crowers with the dual feed oiling.

I was thinking like Don, that maybe a hydraulic would be good if you were just on the street. This is probably too small for you, but with 1.8 rockers, it might work for you, hell even 1.7 maybe.

Thank you, everyone, for your relies. What's the deal, about running SB F*rd Link Bars?

 

[boxerdog]

The normal SBC link bars are too short sometimes, depending on the mfgr. because the lifter bore spacing is longer.

 

[Skip FIx]

Comp has you use SBF for the links. And you have to buy them extra!

 

[boxerdog]

Of course! I would check in with Crower, Isky, Lunati or Howards. And I'm sure there are others who also have a pressure-fed lifter that they will set up for you.

I think the Isky"red zone" lifters are a bushed lifter instead of needle bearings??? The general opinion I get talking to "lifter" people is that they don't like bushed lifters on the street. I don't quite understand that because IH DT466, Detroit Diesel, Cummins & Cat all use roller lifters with bushings. No needles and obviously they work and have done so FOREVER! At WFO they are running what a W does at fast idle! Most solid roller profiles look a bit aggressive for the street, but you could always do a custom. Solid lifters on a hydraulic roller cam is doable. That's what I am planning on doing, if I ever get to build an engine for Bella. This tractor stuff has to slow down. I keep Crower 66204H-16 solid rollers in stock.

I put the isky red zone lifters in my last build and it is a street engine. I have the same thought as Jeff that diesels use bushed lifters and they last a very long time. Just changed a set with 900,000 miles and they were still tight but customer wanted a new set in his overhaul.

 

[Skip FIx]

Red Zone are bushed, Crower has some bushed also.

Humm, may have to test some of my SBC ones on the other 409 block I have.

 

[boxerdog]

Some might work, especially with a lower lift cam. But if they don't, it's a big problem. They will drop in, it's just if they can go through the full range of motion with both lifters moving.

I run a crane .655 solid roller in mine with crower lifters. So far so good. It's everything else I've had issues with. Lol

 

[OkieJoe29]

I got Howards lifters, ready to run out the box.

If you do run solid rollers on the street, bump idle speed up a bit. Gets more oil flowing. Easier to live with on a stick car than an auto however. When my car was a street car it had needle bearing solid rollers, it eventually ate one.

I was also told trying to avoid long idle periods helps. Can be tough to do in traffic though. Of course good oil helps.

I now run the bushed lifters, but it's no longer a street car (well, it still has plates and tags) so I can't speak to their suitability for street.

This my 409 sitting on an engine stand thinking of doing an engine swap for my white 63 Impala just to see how runs. It has solid roller lifters. This is the cam card and the Dyno results. This will be used only on the weekends for occasional driving going to meets and sometimes trying it out on local drag strips. What type of street manners will I be expecting?
Currently it’s a 4- sp with 4:56 gears posi. I won’t lunch the car too hard off the line because I’m sure I’m gonna break something.
