i hate to beat a dead horse but coulnt find anything about this when i searched.
i was wondering if it is worth it to get say an EB RV cam if i dont want to upgrade the exaust the main thing is that i enjoy how quiet my truck is now.
another concerne is gas milage what kinda gas milage are you getting with a mild cam?
i want to know if its worth the upgrade im not expecting miricals but a little extra juice would be nice
thanks

I've got EB's 268 in my 84. I put it in when I did the rebuild and I opened up the exhaust at the same time. Truck is very peppy and I'm happy with the cam. As for being any louder, in the mornings when it's cold my truck sounds like a race truck loping along until it gets warmed up, (kinda like it!) <img src="/forums/images/graemlins/smile.gif" alt="" />, but once it's warmed up quiet as can be. Can't comment on the gas mileage, I have some carb issues that I havn't been able to resolve, runs too rich, so my mileage is for crap. <img src="/forums/images/graemlins/angry.gif" alt="" />

I think EB recommends his 270 cam with the stock exhaust. If you have a header then the 268 is the cam to use. You can always e mail him, he is on line most nights and is really helpful.

I am VERY happy with my EB 270 cam. Definitely more "grunt", if ya know what I mean..

SO, dropping a new cam in and viola more power, more MPG? anything else you need to do?

I'm not saying that you are gonna go " holy crap, I can feel the power " I'm just saying that there is more torque in the low end. And yea, that's about it.

Now, to clarify, I would be of the opnion that if you break the head loose to swap the cam, you need to replace the HG. But that's just me.Once you break those head bolts loose to get the cam in, you really need to chase the holes and get them clean before you re-torque. Anybody else have an opinion on that?

Sorry, but what do you mean by "chasing the holes?" Is this just re-tapping existing threads?

Yup...

so i would have to pull my head to install the cam? hmmmmm (im a newbie to toyotas) what kinda fuel consumption are people getting with the 270?

No, you don't have to pull the head. But you have to remove the head bolts to get the rocker assembly off. To chase the holes you have to remove the head...

Here's the thing... If you have never been in that motor before, and it runs fine and gets good MPG...why mess with that? I have an EB head and cam in mine. But only because I had a blown HG and had to take it apart anyhow. I realize that you only want to drop in a cam, but to do it right ( once again, if somebody wants to disagree) you have to take the whole top of the engine apart. If you just take out the head bolts, take out the rockers, put the new cam in, and bolt it back down...I can almost garantee that you will be facing a blown HG ( head gasket) soon. These are tough little engines, but things have to be just so, ya know?

If you decide to do this, get the FSM available at the top of the page and really dig deep into what will be required. The consider the tools needed..wrenches, socket sets (1/4, 3/8, & 1/2 " drive ) breaker bar, quality torqe wrench, scrapers, extentions, picks, brake parts cleaner, RTV, gasket kit, helicoils....you get the picture. Like I said, I'm not trying to talk you out of it. But like my pappy used to say.." do it right, do it once. Do it half-a$$...do it over and over."

We are here for ya, man....
