i was looking on engnbldr yesterday and came across the 261c cam. is anyone running one of these and if so what kind of power/mpg difference does it make?

i got that cam when i did my timing chain. i noticed my transmission holds a gear longer before it starts to bog a bit on hills. i'm not exactly how much hp and torque i gained from it, but there is a noticable bit of go

i know the feeling, i live in the foot hills of SC and some of the hills around here are pretty tall and long, sometimes i have to grab 2 gears to get up, it sucks. did it effect your mileage any?

nothing really noticable, although my milage is horrible at the moment due to my O2 sensor

mine too, i ordered one from the dealership the other day and they said because of the tropical storm coming through FL, they would get it in on Monday 6-19, hopefully it will fix my mileage woes. it better, if it doesn't i'm out $140 for the stupid thing. on the 261 though, how hard was it to put in? i've turned a wrench or two before, but never really dove into an engine before.

oh yeah, and do you have to adjust the valves or is it just drop in and go?

it wasn't that hard to put in, the head bolts that hold the rocker arms on are a pain though, i thought i was going to snap mine, i had to put a 2 1/2-3 foot breaker bar on to get them to move. then there was keeping the timing right. it was definatly more involved than i thought, not a drop in part thats for sure. and while your doing that you might as well change the timing chain and head gasket, head gasket for sure, timing chain only if it hasn't been done.
you might have too, i had a new head to go with the cam as well, so i had to adjust mine

thanks a lot, if i go that route i may have a mechanic do it, i'll probably end up messing it up.

So let me get this straight.,..

If you're going to have to do a 2 hour job you might as well turn it into a 15 hour job?

I really don't think the cam is that big of a job... Be careful with the timing and you'll be fine.

Now, changing the timing chain and the head, better pack breakfast, lunch, and dinner...

to take the cam off you have to remove all of the head bolts, now when you undo the torque on those you risk the failure of your headgasket should you use the old one because its not going to sit the same.
yes i know it sounds crazy, but if your going to do that you might as well go and do it right the first time, 15 hours now, or 2 now and 15 later, its up to you.

You're right about the head gasket... Any time the bolts are removed you need to replace it. I wasn't thinking about the whole job when I posted.

I just did my head and gasket and ran the motor for 10 minutes before I realized there was water going in the oil so I had to tear it all back down. Even though it only ran for 10 minutes it heat cycled so I replaced the head gasket.

Still, the timing cover will add 6-8 more hours to the job... I guess I'd have to make that judgement call based on the condition of the engine. My engine only had 12k miles on it so I wouldn't have done the timing job on it.

But the funny thing is my guides broke and I had to do the timing kit anyway and since the head was damaged I got another with a cam and SS O/S valves too. I figured whileI had it apart I might as well....

I couldn't say whether or not I'd do it on his engine without seeing it...

Good call though.

I Reused A Head Gasket After Swapping Heads On A B2200 To A B2000 Head Once. I Only Ran The Truck For A Week And Then Did The Swap...... The Truck Go Totaled By An Old Lady But The Engine Was Pulled And Is In My Buddys Brothers Truck Who Lives Up In Atlanta.... This Was 2 Years Ago And The Last I Heard It Was Still Running Good.... Those Trucks Are Notorious For Hg Problems . I Know I Shouldnt Have Done That And On A Toyota I Never Would... On That Truck A Head Swap Is Alot Easier Due To It Being A Carbed Timing Belt Non Interfearance Engine. Toyota Trucks Last Forever When Maintained Properly...
