5.9 & a solid roller

-
I don’t have a scale on hand to measure grams but I do have both lifters available for weighing. That is a good question though.

This is a stock Magnum block correct?
Any oil mods done?
Yes, it is a stock Magnum block with no oil mods to the top. It does have oil mods to control windage.
 
I poked around the Hughes site and they sell their "Race Max" solid roller lifters for Magnums; listed as having 270 grams weight, 1.756" seat height (about .500" less than a factory hyd. roller) and oil pressure fed to the roller bearing axles and pushrods. For $655 + fees, plus it sounds like they're meant to work without block mods... I'd rather do that than a heavy factory lifter stuffed with washers lol

Hughes Engines

according to the part no. and pics These are Howards 91734.....and they say These are for 318 & 360 except Magnums....who´s confused? Hughes says These are for Magnums, Howards says they are for LA, not Magnums.....

Here is how a guy did it on his magnum with LA heads. He has not ran the engine yet

I saw that on the Howards site as well but that doesn't make any sense, I can't think of any reason why they wouldn't work in a Magnum. Only difference is the lifter bosses are a tad higher on the Mags. Just take out the spider that holds in the stock lifters, use adjustable rockers, and longer pushrods should be good to go.
 
IMO the Howards catalog is a little jacked up, browsing it some more the way they categorize parts based on the engine model is very inaccurate. They list retrofit hydraulic roller lifters as LA OR Magnum, not sure if I agree with that... also I couldn't find anything specific to just Magnums and not LAs.
 
Welllllll, it depends on what your doing I guess. If it works, it works. I don’t remember hearing out prior to yesterday

Oh yea, no problem Bobby!
Toluene56, remembered I have W5’s at the ready. (Close to it) and assumed correctly that is where there going but that is not (and hopefully not) an issue. He listed the TD set up, which is where I want to go. I could do a standard LA W 2/5 set up as the head can oil through. But not the block as cast of course.) It’ll be a while before I get there.
(WAS hoping to be there already but.....)

I was just wondering who may have installed a whopper of a cam and gone racing with a Magnum block and if they did anything. So guys are daring/smart/stupid (?) and will just stick it with a monster cam and go.

Enquirering minds wanna know......
It has ran...tis glorious.

Oh so this is your car I got the pics from? If so that is so cool. I didn't know this was your engine build.
 
Toluene56, forgive my ignorance but, for your engine, you have a magnum block, roller lifters made for an LA Block, custom length oil thru pushrods for an LA valve train, LA shaft mount rockers and LA style heads?

Look at the pictures again. Take a minute.

That answers it, thanks!
LMAO! Yea it kind of does. I really didn’t want to answer his question. I actually don’t remember what he did for pushrods and rockers but it’s around here somewhere.

Oh! You can get his (or any bodies) attention by putting the at symbol in from of his screen name like so....

I I had a set of solid ball/cup pushrods that just happen to be the right size, lifters are comp 8043-16 which are for la or magnum but they do oil through pushrods. I got a killer deal through Amazon for them. Rockers I think are old comp roller rockers no marking but they kinda look like comp or possibly crane.
 
Rumblefish I think was the OP. I'm fitting a Comp solid roller in a LA 360 (pre magnum) with Lunati Solid roller lifters. The lifters fit no grinding, no problems. Looks like they won't be a problem exposing the dumb bell
section out of the oil gallery/ lifter boss. I'm going to drill the 2,3,4 oil galleries to the crank. And I want to know do people do the oil cross over mod in the valley when running solid rollers? and if yes why?
Cheers

Sorry for the delayed answer.

The answer is no because the cross over tube is done for Hyd. And Hyd. roller lifters. The lack of oil is because the driver side oil valley feed is restricted at the front of the block at the drivers side. This seems NOT to be an issue with solid and solid roller lifters.
 
I agree with RRR's first post on the subject
oil shafts from the rear of the heads and not take any oil away from the mains
also oil through the pushrods- oils the cups better
do both
 
You been holdin' out on us, bud.......




Hasn't blown up, even pulled the intake to fix my oil leak last night, everything still looks brand new. No weird wear marks or discoloration from heat. So far the oiling mods are working.
 
I've put about 300 miles on mine so far with the same oiling setup as Toluene56, haven't pulled the valve covers to check the valvetrain but it runs great. Almost no valvetrain noise either, and oil pressure at hot idle is a hair under 20psi with a regular-volume oil pump. Part of the reason is I'm running pretty thick oil but I still don't think an HV pump is totally necessary.
 
get's cold where you live
I'd run 0w- 40 eurospec oil- the bmw long life ll or MB 229 spec
made from natural gas with high ep
Walmart has very reasonable like $23 5 quarts
Mobil1, castrol, Penzoil all the same stuff-- made in Belguim
get that start up oil flow
