Great description of these. Besides the T&D Race setup, do any of the other setups requiring milling aluminum heads (Edelbrock, in particular) for proper alignment? This is something that keeps coming up in different threads/build videos, and seeing how popular those heads are, I can't see why these companies wouldn't make a kit that works with them out of the box.
I'm sure you have seen all the videos on RU-vid of so many people breaking rocker arms. I don't think that they are spacing them correctly for the expanding of the aluminum . I have ran some cheap roller rockers for years on my 390 and I'm not easy on them either and never broke a rocker. If you would be interested or have time in talking about proper spacing between rocker arms. Just a thought thanks
When I was a teenager I had a 62 Galaxie 500 with a 406 motor. One night I had taken my girlfriend home and was going home myself at a high rate of speed. My car developed a miss 2 miles from home. The next morning I started searching for the miss. What I eventually found was a broken push rod on the exhaust valve on cylinder 8. After that I had to replace the left head gasket every week.
Man i never knew this kind of stuff existed for a FE 😮 csn buikd a bullet proof engine here . I heard ticking a had alot of play in my FE after rebuild the shop just used my factory 50 yr old rockers and pushrods ?😮 i bought the jegs brand new rocker set for 249 .oo😅 .. waited for 2 months or so i guess they were on the ship frim china not sure nothing compared to the basic set here tho .
Why would anyone in their right mind use the stock rocker shafts and stands with aftermarket rockers? The factory unsupported shaft ends are THE weak point in the design. ALWAYS use a rocker shaft assembly that surround the end of the shaft.
Great video Brent! I'll be ordering a set of your non adjustable roller rockers real soon. I've already got a brand new set of aftermarket shafts, do you sell the billet stands and spacers or would I be better served to order them directly from Precision Oil Pumps? Thanks!
If I keep the stock 1967 mustang 390 FE cam, with solid lifters, and change to the Lykins non adjustable roller rockers, is it really that much trouble?
Can you explain proper adjuster extension in picking correct length pushrods. Something about the angle between pushrod and the line drawn through adjuster intersection and rocker center? On seat and 1/2 lift and full lift?
I do have a couple questions for you Brent. One is is it possible to convert yours to an adjustable and is that a possibility it is available that way in the future. Ans one more is , How much spring pressure do you feel the POP stuff is good for?
I'm currently running a set of Harland Sharps needle bearing setups. The problem I'm having is the end stands are flexing, in fact both shafts have broke at the first stand stud. Might have to switch to T&D.
I have the T&D set up. It has broke shafts twice. Each time a nut backed off and allowed flex in the shaft. I founs when I switched to different nuts never had a problem since. Only ran 2 seasons nbut so for no issues. Might try to see if that helps you.
Do your end stands surround the end of the very end of the shaft? As in outside of the end rocker arm. This usually prevents the end of the rocker shaft from snapping off due to high spring pressure.
In your opinion do you think springs that come with AFR heads with 155 seat pressure and 450 open pressure would be enough spring for these type of large aluminum roller tip rockers? Cam is hydraulic 246/ 262, @.050, .642/.642 lift? Valves are 2.165/ 1.60
Technology has moved from the ridiculous spring pressures discussed in this video....they shot Kennedy and landed on the moon....move forward. Conical springs and lighter components can run well into 8000 rpm with spring pressures under 450# springs. Do some homework....
My favorite part of having a RU-vid channel is when guys like this call me out, while they sit in their recliner and read about other people building engines. It's always an ego boost when you get to tell a professional engine builder to do their homework, isn't it? Make you want to puff your chest out and feel good about yourself? I have ran 8000 rpm with those kind of spring loads. But not every engine is an LS and not every engine has lightweight valves. Not every engine is a street engine. Not every engine is a hydraulic roller. Not every engine is a Cup engine with 6mm hollow stem titanium valves and non-adjustable rockers. Maybe you should do some homework before you come across like you need to take me to school.
Love your work Brent. Hopefully I can support your business further down the road oo optimising my 390. I'll be in touch or maybe even come and visit from Australia if I can make it happen. Thanks for the education on my classic engine. I really want to get her singing 😁
