ok thanks from what i have been reading that seems like it will be a good cam for the motor. I dont wanna get to radical of cam were i have to many problems but i want something that sounds and performs decent. do you think this will be my best bet along with iskys ani pump up lifters. i dont use the truck as a truck just want something that i can have fun in and get back and forth to work with. i have a 3,000 stall in trucjk now

 

ok thansk again do you know were i can hear sound clip of both cams. i havent heard one of theirs and am curoius on how they sound. I apperciate your help

 

does the 278 have a very aggressive lope to it is there a big difference between that and the 264. i would rather have better performance i am curios how they both sound thanks

 

I may be wrong here, but I believe a lumpy sounding cam gives better high end and a smoother cam gives better low end torque.

What's your preference other than sound?

 

I want performance the trucks a daily driver I want to sound good buy want it to be reliable to i want the biggest cam
I can without having to replace springs and worry about breaking thing s

 

Elgin makes a cam with 274/274 duration and .450/.450 lift on a 106 LSA and a 102 ICL. It works very well with a 3,000 stall and is very mild. Has killer mid range torque too, BUT milage is not the greatest. People have swapped it into otherwise stock engines with headers and have had good results. You need a good exhaust system with it though.

 

search youtube people film everything. If it doesn't have your specific cam there will be one that is pretty darn close.

Its the elgin cam I was talking about, its the one that comes in a Comp box labeled 274h06, but its the same cam, all the cam manufactures sell a version of this cam. Elgin just has the best price.

 

thanks it does sound pretty good will the 201278 sound about the same

 

that cam, the Isky 278Mega, will actaully have an even more radical idle and will nto work with a stock converter as F'bird already noted. It will give you mpore hp up top, but sacrifice some low end power. Not a bad cam if you build the rest of the truck to suit it. For an otherwise stock truck though the cam I showed you is as large as I would go.

E1785P is part number for that cam i recomended. Works fine with "z28" springs.

 

Here's a video link to the sound of the isky 278 cam. Well, from inside but you get the idea of how choppy it sounds.

thanks that cam sounds reallly good can i get away with 3.73 gears i think the 278 is what im going with on a old cam how can i look up and see what kind it is thanks

If you want to run that cam I would install it advanced about 6º.

 

With a 383, I didn't have enough vacuum for power brakes after switching from an Isky 270 to 280 Megacam. I would think it would be even harder getting enough vacuum with the 278 in a 350. We did an almost identical 383, but with a comp cam xe (274 I think), which ran the brakes fine. This surprised me since I didn't expect the 2 deg tighter lsa (108 for the Isky vs 110 for the CC) to have such a noticeable effect. The Isky was a little stronger and at the track the 2 cars were within a couple tenths (even though the one with the CC cam was about 400lbs lighter).

IMO, I wouldn't pick a cam to get a certain idle sound.

 

the difference between the 278Mega and the 264Mega is 20 degrees of duration on intake and exhaust @.050". That is a HUGE difference. The 278Mega is a nice cam for a saturday night cruiser. If you are planning to just cruise in to the local drive ins and buger shacks then I would run it, you have a 3,000 stall already to match it nicely.

If you plan to use your truck as a truck though I would rethink getting a cam that big.

If you are running that truck as a saturday night cruiser post some pics of it, I love those old boxy trucks when they're all shined up and 2 feet off the ground.

 

If you had set up the ignition timing curve for he cam properly you would have had a lot more vacuum for PB's. A stock timing curve will not work.
The distributor has to be modified to allow more initial base timing at idle with a big cam like this.
24+deg at idle is required.

You're probably right. I had an MSD probillet with the black bushing (+18deg centrifugal) and one heavy silver spring and another light silver one (all in by about 2800). I ran 18 initial (+vacuum advance) giving me 36 total. When checking timing, it was super rough running and almost wouldn't idle with the vac adv plugged. I can't remember if I ever checked how much it was advanced at idle with the vac adv connected, but I had it running on the timed port. I tried to run the vac adv off the full vacuum port, but there was too much part throttle/under load pinging. I've heard to always use the full port unless you have emissions stuff on the car.

At the time I thought I could run an adjustable vacuum can to dial things in better off the full vacuum port, but that particular distributor wouldn't accept the part I had (can't remember the vendor). I was starting to develop a major hate relationship with my engine's vacuum and going to manual brakes was an easy way out. This sucked with my 4 drums but works much better now that I have discs up front.

I guess my point is the 264 could be stabbed in and only need some minor tuning. This is not the case if you go bigger.

 

I use the truck to go back for to work and mess around with on weekends will the 278 be real hard to tune thencam it had was pretty big indont kno
w specs

 

not real hard if you just give it enough initial timing.

Just to let you know, you don't have to run the biggest cam you can find...

 

I know I want something that sounds and performs good

 

The cam I showed you sounds good to a lot of people and will give you more tq lower in the RPM range. A lot of the sound comes from the headers and exhaust too.

Its your truck, so do as you wish, but I doubt you will be revving that thing over 5800RPM much, in which case the 278Mega is too big of a cam. Performance can be diminished from going too big on a cam, not just too small. More often than not rookies over-cam. We all learned the hard way that sometimes smaller is better.

 

Maybe the smalller 264 will be better do I have to degree that cam to I want the most performance for the money with the 3000'stAll will the 264 be a better choice

There's also the 274Mega...

And a LOT of other cams in between the two...

you should degree any cam you get.

 

you can make your own degree wheel (I made mine), and degree it relatively easily as long as the plugs are removed from the heads. I made my wheel when I was 15, and still have and use it. Also degreed my first cam with the engine in the car.

 

What would the best size betwen the 264 and 278 to run to get what I'm looking for
