Vibes from an engine running are different from out of balance vibrations. But if you think it's balanced now and you aren't doing anything to throw it out of balance, I guess you could skip it.
 
Got the head back yesterday. 128$ out the door to install the valve seals, grind the valves and take .030 off the head. Now I have to rip into the lower end and buy main, rod and cam bearings. Any suggestion on a good source that's not going to put a hole in my wallet?

Also I have yet to figure out who to buy my RV cam from. Anybody have a preference?



Feel free to laugh thats why it's that color.

I got my main and rod bearings from Toyota with a 25% discount they were very close to aftermarket prices.

I was thinking the same thing. I just didn't know if there was anything out there that was any better.

Also getting new rings. Any ideas on good ones or should I just stay with OEM?
 
Since I had mine bored and new pistons, i just got them from the machine shop, they were Hastings, IIRC

Saw Downey has two types

13260 F and 2F Torquer Cam $220.00
13270 F and 2F Horsepower Cam $220.00

Downey now offers two Cam choices for the F and 2F Landcruiser engines. The Torque Cam provides better acceleration between 1800 and 4000 RPM. The Horsepower Cam is a better full-throttle performance Cam with 2200 to 5000 RPM effective range (Headers and Holley Carburetor recommended). NOTE #1 – Stock Landcruiser cam duration (over-lap) is ridiculously too long. We have shortened the duration to improve performance and radically reduce emissions.


and MAF

13511-60060BRV MAN-A-FRE BILLET RV GRING CAMSHAFT $310.00
13511-60060 MAN-A-FRE BILLET STOCK GRIND CAMSHAFT $225.00

By using a fresh cast billet we achieve several advantages. Unlike re-grinds which must make the base circle of the cam much smaller in order to achieve higher lift and durations, thus creating steep ramp and lobe angles and adding stress to the valve train. A billet retains the large base circle similar to the stock camshaft, enabling the use of higher valve lift and duration without drastically changing the stress level. Another advantage is in the area of the distributor drive gear. On the stock Toyota camshaft the distributor drive gear is pressed onto the camshaft. Over the years this drive gear can come loose, and out of line, or begin to wobble with obvious consequences to ignition timing integrity or damage to ignition distributors. On Man-A-Fre billet camshafts this is not possible as the distributor drive gear is a cast part of the actual camshaft, and can never come loose. Advances in metallurgy, and grinding techniques couple to give us a camshaft stronger than stock, but less expensive than an OEM. replacement unit. Man-A-Fre's RV grind camshaft is machined from a hardened cast billet, and ground to our own RV spec grind. These camshafts will deliver power increases across the entire rpm band from right off-idle all the way to redline. Overall duration of these camshafts is 262 degrees which produces the most favorable overall power increases without sacrificing bottom end torque. Camshafts with durations of 270 degrees or more will give stronger pulling power at higher rpm levels, but do so by sacrificing bottom end to midrange torque and throttle response. Our stock grind camshaft has all the advantages of our fresh cast billet, but in a stock grind configuration for those that prefer. All MAN-A-FRE billet camshafts are drilled for use with both F and 2F cylinder head oiling systems. We highly recommend the use of new lifters, and cam bearings when changing camshafts. Always use assembly lube when doing internal engine work.




So do I have to replace the lifters?
 
Marshall, did you either etch the valve cover or use a self-etch primer before painting it?

Yes, or have the old ones resurfaced. IIRC resurfacing the old ones was about $5@ x 12 = $60 and new Japanese from CCOT were $100. I went new.
New cam = New/resurfaced lifters http://coolfj40.stores.yahoo.net/lifter.html

Pappy, why did you delete that.........? Good info and when you are that deep into a motor, I'm not sure that is the time to save $50-60.

New cam = new lifters:beer:

Because I F***d up. I only multiplied by 6. It should be twice that and it looks like I didn't get it gone in time :eek:

DAMN! you mean OEM lifters are $256!!!!!! Well, we'll/I'll see how the CCOT Jap-Pan lifets hold up. That makes resurfacing look like a deal.

Now barf up why you bought only 6 lifters.........:D

I didn't buy any, I had mine resurfaced :D. This was simply Internet homework.

$28.32 list x 12 = $339.84 - 25% for CDan discount = $254.88 ... yep, OUCH!

MAF cams also recommend stronger valve springs and the lifters to be crowned...

Yeah I saw that. I'm not really interested in changing springs. I heard Mark W sells a good cam. Anybody have an opinion? Or is the color really freaking you out?
 
On the stock Toyota camshaft the distributor drive gear is pressed onto the camshaft.

:confused:... howd they get that lil gear over dem lobes

Colour is :cool:

Can I have the paint code:D
