I am thinking about putting a hydraulic roller cam in my 500" Indy headed -1 motor. It currently about 11:1 compression with a solid roller cam around .630 lift. Who has the best cam and lifters since this will be my first hyd roller motor?

What RPM capability do you require? And what is your reasoning for switching from a solid roller to a hydraulic?

I haven't assembled it yet, but Dwayne Porter (fast68plymouth) spec'd a hydraulic roller for my dad's 540" hemi project and we went w/ a set of Scorpion hydraulic roller lifters.
I've been VERY pleased w/ every other cam/head/valvetrain combo Dwayne has helped me with...no reason to think this won't work great.

I have had great luck whit Morel roller lifter on 2 500 cube street engine but as stated before it hangs alot on how mutch you need to rev the engine!

Talk to Dwayne at Porter Racing Heads or give Brian at IMM a call. Both guys have experience with BB Mopar hyd roller setups.

I've run a few hyd roller cams in BB Mopar engines and it can be frustrating to get the cam lobe, lifter, rocker arm and valve spring all happy together. If you get it wrong the lifters will stop working early and the power goes away.

You shouldn't have much trouble finding a nice hyd roller cam but the lifters can be an issue. I run Comp lifters in my street car and they work just fine but there are guys who say they don't work. Morel has lifters, but I think that IMM uses Gaterman for their hyd roller lifters.

I went with the Morel High rpm versions, $940.00 from Hughes, they work good so far, car ran 11.33 @ 121, 4100 lb Charger, no tuning yet, they are a little noisy when cold, you can adjust them .020 from bottoming out of the plunger, & they also recommend no heavier than 5-40 oil, I am running 10-40 Lucas racing oil with no problems. pulls great over 6200.

If it were me doing that i would go whit street lifter then and stay whitin there spring/rev limit for long life ! I have .600 on roller rockers 1,6 whit Morel street lifters and that engine is nice up

If it was me building your motor I would select a tight lash solid roller cam with a really good set of bushed solid roller lifter and matching valve springs, pushrods and so on.
Set them once when cold and again after running the motor long enough to get the oil and coolant temps. up to or above 160 F and reset the lash once more and enjoy the higher RPM of the solid roller cam and lifters with those good heads up twocents
I'm not a big fan of hydraulic roller lifters, yet, for either Mopar BB or 426 Hemi motors yet due to past bad experiences with hydraulic roller lifters in them down twocents

do you think the lifter is operating like a hydraulic, or a solid?

We use Gaterman and Topline and have been very pleased with their performance.

more like a solid,but with dampening for the roller, no lash, so hopefully they will last longer on the street than all the horror stories of solids failing from street use, I said you can adjust them .020 from the bottom, mine are not done that way, mine are 1/2 turn from zero.

Gaterman supplies Howards with their link bar lifters for most applications.

Good advice given my experience with hydraulic rollers. Initially, my valve springs were not set-up properly and likely weakened quicker than normal too though. The valve train harmonics really beat up my rockers as a result of it. Even with all that going on the motor spun out 684 hp at around 5400 rpm before the springs lost control of the valvetrain.

Cab, thanks for the tip on checking the lash again with the motor warmed up. I haven't done that yet on my new solid roller valvetrain, but I will.

Dwayne Porter sure nailed the latest combo in my case too. My motor is running stronger than ever even with 2 full points less compression and burning California pump swill. I haven't dynoed it yet, but it sure runs a lot smoother now with the solid roller valvetrain.

The more you rev the more you stress component and valve springs will set the bar for witch lifter you need to use !

If you build a street engine use street lifter for long life.

I would like to keep the RPMs in the 3-6k range since that is a 100% street can that will never see the track again. I have other race cars when I have the urge. I will put between 10-12k miles per year on this car and drive it to work most days when the weather permits. I am looking for the reliability and about 600-650HP

I have a problem with understanding why someone needs a 650 hp motor that is only going to be street driven and never raced and wants to be reliable???? That is a lot of strain on parts to make that much power to be pounded on at low speeds for bragging rights. lie!!! and leave it stock. That's my .02. Don't get me wrong I like a lot of hp but i use it for what intended.

Lol. Well I didn’t say I wouldn’t drive hard! The reason I have is I have 3 other race cars and miss a little street action. I already had it built with a world block, decent parts and -1 heads and drive it maybe 500 miles per year. So instead of building a new motor I should use the parts I have. I would think it should be possible to make 600hp out of a 500” motor and be very reliable.
