just wondering if any of you have had any experience with any of the after market cams, 268, 272, anything like that. what about the ebay cams?these cams are about half of a comp cam. any suggestions i drive on dirt about 90% of the time in mud/snow and no rock crawling. i have 235/85/16 tires and am looking for a power adder to be able to push them in 4wd not 4 low up hills/deep snow. what would you suggest?

 

20r and 22r cams are interchangeable, I run a Comp cam and coudn't be happier. Beware of no name cams sometimes they use cheap blanks to manufacture their cams. Also be aware that to get big top end power out of any r engine you will have to machine the valve stems.

 

LCEngineering.com, good stuff.

 

good link they have a ton of 22r and 22re stuff

I run the engnbldr 261C RV cam and i love it so far. Has a crazy lumpy idle though.

 

Running EB's 261c Crawler cam in a .020 over rebuilt 22r. I have the rv head with oversize valves, Otherwise its bone stock. Idle's smooth as silk, pulls hard right off the bottom and screams when you ring it out.
Truck has stock gears, tires, trans, etc.
I'm very happy with the outcome but its no sbc.

 

Is your cam an older one from engnbldr. I purchased mine a couple months ago but and I think something is changed from the original grind. You said yours idles smooth, but mine is all chattery, a good chattery though, not missing. On the current ebay listing (same as the one i purchased from) he mentions a chattery idle.

Ouote. "THIS auction listing design, our 261C(Crawler) is a mild lift fast ramp longer duration profile, it has a chattery idle so everyone knows it's NOT stock, and VERY fast off-idle recovery to around 5200. It features a full powerband, and is the more "sporty" of our two popular profiles."

My head is recently rebuilt but mostley stock. Anyway just wondering what the difference is.

 

You sure about this one? I thought I've read something about 20R valves not having as much lift, so some aftermarket cams would try to open the valves "too far".

 

From engnbldr once again.
"This Hi-Torque RV camshaft profile fits ALL of the 20R, 21R, 22R, 22RE, 22REC 4 cylinder SOHC engines found in Celicas, Pickups, & 4 Runners, between 1975 & 1995"

There may be some cams that are not interchangeable, but I have not run into or heard of such.

 

thanks for all of the posts. i found a trd stage one for a great price so i am going to go with that and a weber 38 carb. i cant wait to see what kind of a diff it makes in that old truck.


was it a wow type of difference or very noticable improvement??
