2F camshaft + lifter options - Pirate4x4.Com : 4x4 and Off-Road Forum

I'm helping a friend build his 2f engine for his 78 FJ40.
Looking for Cam and lifter options, not interested in shifting the powerband up in rpm any at all. It is going to be all stock with the exception of the .030 or .040 over bore and crank turned, all new bearings, new valve guides, valves and seats reground, no head resurface so the C.R. should be fairly close to stock.

I've found downeys camshafts and they mention that the overlap of the stock cam is overly long in their words but with no numbers .... well sounds like they are just trying to sell bumpsticks and does little convincing to me without some hard numbers.

I see clifford no longer lists a 2F cam. Found manafree and see their $300 RV cam with mixed reviews here and there.
So what options are there out there for a new or reground cam as close to stock as you can get ?
If someone has used a reputable regrinder thats 2F wise would you please post the contact info? We're looking for longevity not accelerated valvetrain wear with little torque benefit.

And if someone knows the stock lift and rocker ratio that would be great too, said he wants me to mic an old stock cam someone rustled up for him outta a parts motor with a rod slung.

THANKS !!!

For fully new cam shaft I believe Downey and MAn-A-Fre have the only ones. I believe they have 262 degree grinds?
There are sources for reground cam shafts.
You might also check with Mark at Marks off-Road he may have a OEM laying around.
I have the Man-A-Fre RV and it works fine.
For lifters take the stock ones to a machine shop and have them reground. not worth buying new ones IMO.

Nice Mud pimp.

Get a Sealed Power # 221-2202. It is a new stock cam. Make sure you get new lifters. CCOT seems to have a good set. You could always have yours reground and have your lifters reground as long as the core cam is usable. What is the condition of your cam and lifters now? Why not just run what you got?
