Author Topic: Engnbldr's 261 crawler cam vs. the 268 .425 (Read 22824 times)

Volcom · « **on:** Feb 20, 2006, 12:08:10 PM »

I plan on running one of these two cams. I don't have a ton of money to throw into my engine rebuild project and the Engnbldr cams seem to be the most economical for a tight budget. I am comparing to two cams he offers, the 261 "Crawler" cam or the 268 cam. This 4Runner is going to be a weekend rockcrawler. It's not going to see any DD. I will be driving it to all the trails here in Colorado. We've got some steep mountain passes and the 22RE isn't a powerhouse. I know it's not and plan on it being slow up the mountains.

Which cam would you choose and why? I've reasearched cams on numerous boards until my eyes have hurt and still can't make a decision.

Thanks!

unless the stock cam is in bad shape dont waste your money, the engnbldr cams are just barely over the stock cam if at all

whats the lift of the 261, obviously it has 261* duration, i bet it has .405 of lift,

i wouldnt bother , you need 430 lift to see any noticeable difference

What would you suggest for a 22RE over the engnbldr cams? Thanks for the reply.

yea they are more expensive than the negineblder, but they are FAR from stock

i run the 20/22R stage II race cam .460 lift but it dont really idle smooth

Skinny_Pedal · « **Reply #8 on:** Feb 20, 2006, 04:17:22 PM »

skinny, have you clicled the link in my sig?? does yours sound that "good"

79coyotefrg · « **Reply #10 on:** Feb 20, 2006, 04:49:17 PM »

i just read the header of this topic, the 268 cam has a .425 lift

thats not bad

Ramrod · « **Reply #11 on:** Feb 20, 2006, 04:59:47 PM »

I called engnbldr and asked him which of his 3 cams would be best for my truck and he said I should go with the 268 and I did. Havent run it yet though

79coyotefrg · « **Reply #12 on:** Feb 20, 2006, 05:11:15 PM »

the 425 lift should be decent, and a step above stock

Ramrod · « **Reply #13 on:** Feb 20, 2006, 07:08:12 PM »

according to all educated writups I'ves seen on toyota camshaft design it is not so much about lift it is more about the lobe design, espescially the duration and separation. The motors supposidly cannot handle too much lift with the efi and still pass smog and not have the valves hit the piston

Ramrod · « **Reply #14 on:** Feb 20, 2006, 07:12:11 PM »

oh yah I just remembered that I read a bunch of dyno charts by grumpy4x on pirate on all the different toyota midrange cams of every company and they were all pretty much the same. The 268 had about 1avg hp more than the 261 and supposubly ran alot smoother and had a longer powerband also

well Bigblue, i dont know about the "write ups" but from 1st hand experience i can tell you my Lc Engineering stage 2 race cam is just that a race cam, designed specifically for the 20/22R by LCengineering, and tested by me, i ran it in a bone stock 20R and could pull out to 5500 rpm with ease befor the cam i was lucky to get 4000 rpm, after a weber carb and LC headers, i could take it to 6500 in all but 4th gear

when i pulled that engine due to being under water, ( long story) i installed a stock 81 22R block and 2 times in a row broke the speedo cable off after passing the 90mph mark on the speedo

for a short time i had this same engine in my celica and consistently broke 120 mph

yes the pistons have to be notched or you risk bending a valve if you go over 6000 rpm, which i did at one point, broke the valve off ruined that head and badly mangled the block but i'm running the block now, bored .060 oversize with the cam in another 20R head
i used plasma rings and they take for ever to wear in but after 2000 miles it seems to have more power everytime i drive it

Ramrod · « **Reply #16 on:** Feb 20, 2006, 07:33:38 PM »

I doubt that cam would work with efi and by the sounds of it I dont think it would work to well for rock crawling

79coyotefrg · « **Reply #17 on:** Feb 20, 2006, 07:58:50 PM »

i dont know my weber floods befor i ever get that far after a 45 degree angle i have to open the throttle a good bit to keep from flooding out and dying

besides my truck isnt a "rockcrawler" its a general use, "crosstrainer" i guess you could call it

but i can sling even red clay off my tires

79coyotefrg · « **Reply #18 on:** Feb 20, 2006, 08:01:18 PM »

no its not for efi, but they make one a bit milder for a efi i think its a .440 lift this cam a weber, holly or sidedrafts is a must,

but that 425 lift cam should be a nice step up for a rock truck, and show improvement on the free way to boot

Hyena · « **Reply #19 on:** Feb 20, 2006, 08:56:21 PM »

Im gonna go with the 268 in the engine i am rebuilding for James. If i like it i will put it in my truck too when i eventually rebuild my engine which should be soon since it is running like crap. hopefully i can dog it out untill after the tin benders jambo then it can do what ever.

I ran engbldrs 268 cam in my 22RE and it gave me a bit more power to get up to speed (bottom end) but didn't really seem to make much difference at highway speed. I sold the truck and have an 89 extra cab with the 22RE now and I just had the exaust done from the cat back with 2.25" to a 40 series flowmaster, and I noticed that I now have about the same amount of power as the cam gave me on my 94 with stock exaust. I personally would get a cam with bigger lift because the 268 is so close to stock.

I got it on the doorstep yesterday

I know it's not going to make a ton of HP but it should help out a little bit

kyle_22r · « **Reply #23 on:** Feb 26, 2006, 11:55:55 AM »

last i checked, EB's cam was 268 duration(durrrr) and .430 lift.
