Hydraulic roller questions
In order of how you asked the questions:
1. Which cam do you have? Cant help until unless you have the part number....and NO to the MP springs. Roller lifters need a lot more spring pressure to keep them planted on the cam (bouncing will destroy the lifters REAL fast)
also, roller lifters are relatively heavy; thus, needing more spring to control them.
2. Call Smith Brothers Pushrods, they can hook you up. Your tooth picks will not last with roller spring pressures.
3. Rotators, trash them
you will need new retainers and keepers that match the springs.
4. I dont know, someone else will need to field that one.
5. Roller ALL THE WAY! More power, no flat cam problems, etc.
1) Here is the
cam, it is a street deal for my Barracuda. Not really wanting to spend a lot of money, unless it is needed.
2) I understand that, but it had roller to start with. I used to use vasco jet springs with my solid roller, but wasn't sure about this hydraulic stuff.
3) Thanks, I planned on it, unless someone convinced me other wise.
5) Ok, that is kind of the reason FABO taught me to find this motor, but I have all the other stuff in stock for the flat tappet, and just thought I would ask.
Thanks moper, appreciate the feedback and information!
I have never had much problem with flat tappet cams, and keep the additives in stock. I have the strong pushrods, springs and cam on the shelf, but then, why did I search for this low mile hydraulic roller motor for a couple years?
I would really like to just find a drop in spring, but in the link I provided from Comp, they didn't reference any spring applications. Maybe I need to dig a little deeper.
As I mentioned earlier, I have been down the solid roller path before, and understand what needs to be done. Bronze gears, massive spring pressure, etc. etc. But this hydraulic thing, is a little different to me.
I would give HUGHES engines a call, they are very helpful and should be able to set you up with everything you need, Phone Sales & Technical Support: (309) 745-9558

Will do, thanks!
Did your 308s come with a hydraulic roller block?
Go beehive on the springs if you can at all. They're expensive, but worth it.
I had thought Comp beehive 26995 were a drop-in for 308s and such, but they're only good to .500 lift. Double check this before you spend money, or anything else, I'm far from an expert.

Hydraulic rollers can make a ton of power, but retrofitting is an expensive gig. Unless limited by rules, I run hydraulic roller on all my junk.

Yes, I talk about the motor in
this thread, and it is not going to be a race motor, the stock 318 just isn't doing it for me. The cam I have is just south of the .500, so maybe that is the best answer.
I will contact the tech guy at Comp that has helped me in the past and see if the 26995 is a drop in. I would love to avoid whatever possible with the machine shop.
