Camshaft
Here is what we now know:
Currently the 2F and 3F-E camshaft carry the same Toyota part number. This 1988 new features booklet (page 18 of the PDF, 122 of the booklet) states that the cams are different. Mark W uses Delta Camshaft Part number KC859 with 262* advertised duration. I also use this cam from Delta. EDIT: I'll try to keep the valuable links up here.

The 3F & 2F camshaft profiles are exactly the same. The only difference is the 3F cam is 5* advanced.
Advancing the cam timing brings torque earlier, helping to make up for the torque that was lost when the crank was destroked. __________________ Thanks, Jim C. TLC Performance Underhood Janitor, cleaning up other people's since 1988.

So the advancement is in the way the camshaft and drive gear mate-up? (i.e. It is the drive gear that is different rather than the camshaft?)

If it was spark timing we were talking about.

I am curious what the power band will look like between the stock 3FE cam and this KC859 cam. Are we losing any power or gaining it?

Is that cam for torque or hp?

Good thread on F block camshaft stuff.

Had my cam reground by Delta. Specs are below. Great improvement on top and bottom end IF combined with header, shaved head, engine balance etc. By itself I don't think you would gain much.

The change in cam timing is accomplished by moving the woodruff key 2.5* on the snout of the cam.

Interesting.
Jim, just out of curiosity, what cams have you run now or in the past? If the profiles of the 2F and the 3F-E cam are the same, but the 3F-E cam is advanced 5*, why does Toyota carry only one camshaft? Which one is it? Does 5* make that much of a difference to matter? I'm going with the Delta Camshaft cam. I'm anxious to feel the difference it makes in the 2F-E. __________________ A Ron Using one cruiser to go mountain biking, and the other to collect dust. 2F-E Article McNamara gear writeup |

Delta cams said they would do a custom cam as well.... so if that is the case and it doesnt cost much more what would be the best spec to go with for the 2FE? __________________ 1989 FJ62 Factory Clean... 2FE "Good people sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf" "Honor Our Fallen Brethren." |

Also some good reading on cams. http://forum.ih8mud.com/40-55-series...uild-tech.html starts around post 28. If I had to do it over again I would have gone with the Delta cam over the Billet cam. Just because it cost so much more. __________________ Marshall UC VP & Token Club Cook Greenville, SC Big Gay 2f Build The Great Cruiser Part Links Thread Buying a Land Cruiser Guide "On second thought, let's go to Chat.

The toyota cams are way weak, w/ only the thinnest of surface hardening. The RV was tried in a very strong 2F that already had been punched 1mm, milled, big valves, big 1975 carb, non-US dissy, headers, FJ45 flywheel & clutch... Swapping in the RV cam made a noisier valvetrain, but no noticeable improvement in power or economy. It ended up coming back out and reinstalling the customer's old/new OEM cam. Been using the USA billet stock replacement with excellent results. Melling MC803 or SealedPower CS803. Quote:
The current cam is the 3FE cam, but it is backward compatible w/ all F-series engines. It doesn't matter to toyota. I don't know if it matters to you. Quote:

I agree. I had an old Chevy truck with a straight 6, I put in a hot cam, and had more power at the top end, but the bottom end sucked donkeys with nothing else added to the engine.

Melling & Sealedpower are common american parts mfgr.
Order from local parts house or machine shop (if they're doing the build) or one of the big mailorder parts places like Rockauto or northernauto or Autopartsgiant. I only buy/install genuine Joint Fuji lifters. They either come from Cruiserparts, MAF or CDan. __________________ Thanks, Jim C.

The SealedPower/Federal Mogul number is 221-2202.
Haven't bought one for 6mos., so they might be NLA. Bummer. ITM has a solid gear, but like all ITM stuff it is made in China/Taiwan/Malaysia. __________________ Thanks, Jim C. TLC Performance Underhood Janitor, cleaning up other people's since 1988.

Iskenderian makes a nice cam for the F and 2F, they will need yours and reprofile it to your specs.......Ron iskenderian has been doing this with his Dad since the 50s and they have a lot of different profiles for the F and 2Fs....,,,they also case harden the lobes.....a great big + IMO..........price is very reasonable and if you get a chance talk to Ron; he has a treasure of info in his noggin; never steered me wrong in the years have been dealing with him and his Dad
