I've got a set of the Hughes lifters in my 408. They work just fine. Hughes recommends 10w30 oil for use with their roller lifters and that's what I'm running now. I am a big fan of castrol gtx 20/50, have ran it year round with no issues for decades in NW Washington and would like to use it again. Anyone using these lifters using any other weight oil than the recommended 10/30...your experience????
 
I have the solid roller version, morel makes them for people "hyd/solid"...like Hughes, maybe even exclusively now since I bought mine through Doug Herbert for less money "$280.00" ..that was 2011.
I run 20 50w with them.... No where does morel say what oil weight to run, Hughes, once again... is full of it.
I bet there is an un measurable difference in cold oil flow between the 2...one that makes about zero diff in lifter life, but some are dreamers and it helps them sleep at night.. regardless im sure thats their angle with that advice.
Only 2 things with the lifters is to stay at or under 220seat/425 ish open... and keep the solid lash @ .014-.016. The 170lbs seat Hughes says is really odd and Imo overly cautious imo. What decent solid roller could you run and control, may as well stay solid.jmo
 
Never select your oil viscosity by what the engine requires. Only choose the oil by what gives you a warm and fuzzy feeling.
 
I run 20-50 in my roller teen.5 years now still running.About 20K + miles.

I drive from LA to the high desert and to the San Joaquin valley. Temps range from 40's to 115 degrees, rpms in 3800-4200 rpm cruise for 300 miles at a time. The motor is set up .0025 mains and full groove bearings.
I'm fuzzed out.

I did the mobil 1 5wt multi once... no thanks, I like to see higher than 15-18 psi at idle, but I don't own a dyno...so getting warm and fuzzy over 3 hp from an oil change doesn't apply to me ;)
 
That's what I figured too. Hughes probably is looking for a way out of warranty claims with the many problems people have had with their retro rollers. I was among the fortunate, mine have no operational or machining issues. I will be changing to GTX 20/50 this afternoon.
 
I have posted this before...but maybe should again.

I want to qualify this as I haven't tested this stuff since 2008.

Every single time I tested HRT with a 30 verses a 50, the 50 always, every time made more power. Some of that came from the fact you could turn 300-400 more RPM but most of it came from the heavier grade oils ability to resist pumping up, and more importantly, we found that lower grade oils also tend to make the lifters lose lift at lower pressure.

Run the 20w50 and you'll be fine.

On the Callies/Morel website (www.johncalliesinc.com) they list two different part numbers for small-block mopar hydraulic roller lifters. The street version (PN 5321) doesn't show any oil limitation, but the race version (PN 6072) specifically states "Do not use oil heavier than 5W/40".
Here's a link to the dealer list from their website: John Callies, Inc. - Dealers

Is that race lifter the bushed one?

I do know that some of the lifters have an issue getting oil to the rollers.
 
IQ52, you forgot the "/s" on the end. :)

Oil viscosity should be tempered with temperatures outside since heavy weight oil gets really thick and can not be pumped around the engine very well soon first starting the engine.

Run what ever makes you happy. Normally I run a 10/30 - 10/40.
Never a issue.
 
I need further clarification. Does this mean I'm gay and love chevies? Or.......chevies are gay and I love them?
Lol nah I'm just razzing,10 30w reminds me sbc oil like a sum'***** and the owners always run 10 30/40w piss.

------------------------This.------------- mine requires 20w50 now, maybe 10w 40 this winter ??
 
Well to be honest, the 0w20 full synth in above pic(s) was on sale at the time... Just $2,50 per bottle.

I think it takes someone man enough to pour this kind of oil in an old engine... :poke:
