Tool steel lifters.
Perhaps the answer or at least your best bet for flat tappet cam longevity?

I don’t think tool steel lifters work on cast cams.Tom

They do work Tom.
I’ll be using a set on a cast air-cooled VW solid cam, like many others have done successfully. $470 for a set of 8 lifters.

Another vote for Crower. I’m good (so far) with my 60919 and cam saver lifters at a tick over 4000 miles.

The biggest take away I've found is not going cheap on the parts and at least giving yourself some measure of success.
There are no guarantees in the hot rod world but for sure cutting corners will find you on the side of the road more often. I have no issue with solid flat taper or hydraulic flat taper or even hydraulic rollers. I have a couple hydraulic roller engines that have been in service for 25+ years without a valve cover off and they get some abuse as well as 10's of thousands of street miles. One daily is a solid flat taper that has gone 60k miles so far and is perfect. Lash hasn't even changed. Nitrided that cam and installed solid lifters with a lube option on that one. Other daily is a hydraulic flat taper with Johnson lifters on a melling 068 and it's been flawless for years and 50,000 miles. Nitrided that cam as well. |

Having the cam nitrided and use the Hylifts is probably the most rugged combo for a HFT. On a mechanical it is the tool steel lifter with face oiling or a dlc coating, and having the cam nitrided or better yet, a tool steel cam$$$. Adding the oiling option is a good idea, it mostly helps for idle protection though on flat tappets. Last edited by Jay S; 11-06-2024 at 10:41 AM. |

I did a cam for a friends 389 and went with Crower camsavers in the similar time frame as your engine. Couldn’t buy hylifts at the time. He has not got it running yet though. I still think they are the best of the cheaper lifters. Last edited by Jay S; 11-06-2024 at 10:57 AM. |

That's basically it in a nutshell and what I was conveying. Ya have to spend a little more money these days to get at least some sort of reliability and cross your fingers no matter flat taper or roller. Like b-man mentioned I'm doing tool steel lifters on the solid flat tappet for a bug engine as well. Just that is nearly $500 for 8 lifters. But it gives me some insurance. I have all flat tappet cams nitrided these days too. |

Any concerns about FT cam lubrication and low operating speeds? If the engine is loping around at 1800 RPM in OD, is that going to provide a flat tappet cam enough oil thrown on the lobes? Seems a mild FT grind with valvesprings under 270lbs would live longer? Meaning no XE lobes and/or 995 spring setup.

Mine idle around well below 1800 all the time with over 100,000 miles between the 2.
Shucks with the over drive in one it's barely over 1800 on the highway lol |

God I hope there are no oiling issues at low engine speed cause at 50 MPH I am barely over idle

'Splash lube' at lower engine RPM... real or perceived ?

Hey guys,
I am building a 408 for my 67 LeMans with a TH2004r and 3.55 gears. Intent is just a street cruiser and hit the highway when I want to. The engine is a .040 68 400 block, 670 heads, I just picked up the heads and will be having them gone through with new everything and get good forged pistons to get a compression to 9.5:1 max. May even go 9.25. I want to use a stock lockup stall converter I am looking for some ideas for cam choice. I have a Lunati 702 Duration @ .050 (Int/Exh): 219/227 Gross Valve Lift (Int/Exh): .468/.489 LSA/ICL: 112/108 I was also thinking of going roller and would like recommendations. What about Howard’s 4/7 swap cams? And what’s the LS7 lifter use I’ve read a little about? Thanks as always for your input. Thanks
