this is the cam I plan on getting for my 454, going in a crew cab daully, motor is stock, will have an edelbrock performer intake manifold, and headers with a good exhaust.

It has 236 heads on it now but I have a set of 781s that will get rebuilt as soon as I can afford it. Thats just not in the budget right now though

Good bad ugly your a wuss?

I am pretty sure this cam will work well but I always have to second guess myself hence the question
 
Come on guys I realize the cam question has been asked a million times and really I am just second guessing myself probably
 
Thats a pretty good grind. I am going to use the edelbrock 2162 with the performer intake on my 454 build. It's a little more $$, but its computer friendly and should make loads of low-mid power with that intake.
 
Yah I am on a pretty tight budget so the 99.95 price of the summit cam is very appealing. I will have to go think about this I like the comp cams one too I was looking at that one.
 
Eric, I punched these cam profiles into the Dyno 2000, and although not completely accurate because of not having valve event numbers, this is roughly the diff. between those 2 cams:

...............Summit.. Comp Cams
................hp/tq...... hp/tq
2000 rpm..181/474...189/497
2500........229/481....241/506
3000........276/482....290/507
3500........326/488....341/511
4000........373/490....385/505
4500........412/481....419/489
5000........434/456....430/451


this is run on a 9:1/small header/full exhaust/dual plane/750cfm/big valve heads. Cam straight up.
 
Either one looks good. I run a .520 lift cam on stock rockers and springs and it sings good. You can get away with a lopey cam with a big block better then a small block and still keep the low end grunt.

This is the cam I run:

I actually wanted to run a larger one but I didnt want to run a high stall converter. I had problems with the stall reving up on a rock face and then flashing and spinning the tires. There was no crawl control. Of Course this was back in the day before the doubler so maybe now it would be fine with the further gear reduction.

But I'm happy with the cam overall.

Didn't you have 3.73 gears at that time too Matt:D

I see what your saying about needing more convertor with a bigger cam.
I'm running a 268 Xtreme, and will also have the doubler setup, so a little more convertor will be fine for my application.

And Eric, I found the valve timing numbers for the summit cam, and will run it tonight.
 
The one and only time I used a Summit cam/lifters/chain, it dang near took my whole engine out. Ruined a set of 049 heads and put a crack in #8. I had to have it sleeved.

I've used Comp Cams and had nothing but good results. That Xtrme Energy 268 is a sweet cam.
 
Eric, I played around with the summit cam, and the comp cams xtreme energy 262 with small valves, large valves, stock ports, large ports pocket ported etc.
As follows the engine is 454, 8.5 cr, dual plane, 750, small tube headers with mufflers, cam straight up.

Stock canted oval port,...2.06,1.72.............Pocket ported Oval, 2.19,1.88
.
Summit...hp/tq.......CompXE262...hp/tq........Summit...hp/tq........CompXE262..hp/tq
2000.....183/482.....................185/485..................184/483.................185/486
2500.....231/485.....................232/487..................234/492.................236/495
3000.....274/480.....................274/480..................283/495.................283/495
3500.....315/473.....................316/474..................332/498.................333/499
4000.....341/447.....................346/454..................373/489.................376/493
4500.....345/403.....................354/413..................402/470.................408/476
5000.....323/339.....................334/351..................410/430.................416/437

This program doesn't distinguish between large oval, and peanut oval, but I think the difference between canted oval stock port small valve, and canted oval pocket port large valve might be about the same as the difference between the large oval and the small oval. Just my guess.
Hope this helps in your decision, and doesn't confuse anymore.

Thats simmilar to what i'm running in mine. I just went to my local napa machine shop and got there in house cam. (i'm cheap too) i also got the lifters that have a flat side machined into them to allow for better oil flow. i can't remember the exact specs but it was rated for towing with an rpm range about 1500-3000 if i remember right. i have 049 heads and headers on mine. i really like it. idles nice, and has lots of torque. hope that helps...
 
Thanks for all the help suggestions guys and a big thanks to Zim for running all that crap for me

Good news I just got 50 bucks from my MIL she felt bad cause she didn't do anything for my birthday. So I can probably afford the comp cams now.

Anybody have any luck with the Lunati vodoo cams acutally this particular one http://www.summitracing.com/parts/LUN-60200LK/

I am thinking I like the idea of the vodoo cams and will probably search them but I am thinking a little too much about football and food tonight to do much research :D
 
Eric, we were actually going to use the Voodoo 60601:

Hydraulic, noticeable idle. Best mild performance cam. Works excellent in fuel injection applications. Makes approximately 19 inches vacuum at idle. Great for performance oriented marine applications and heavy duty 454 Dually towing applications. Perfect street rod cam.
  • Advertised Duration (Int/Exh): 256/262
  • Duration @ .050 (Int/Exh): 213/219
  • Gross Valve Lift (Int/Exh): .515/.530
  • LSA/ICL: 112/108
  • Valve Lash (Int/Exh): Hyd/Hyd
  • RPM Range: 1000-5500
  • Includes: Cam Only
Part Number: 60201
Jobber Price: $145.11


Then my head guy got looking at the Comp Cams lineup, and We decided to bump up my minimum rpm range some because I felt that there would be plenty of low end anyway, just because of the cubes, and wasn't going to be towing with it.
 
Zim if I ever come out your way I is going to buy you a beer man.

Thanks for the suggestions everyone. I think I will go with the vodoo cam then I like the idea of the newer ramp profiles, kind of new technology in an old engine. Well now that is decided a week till my used intake manifold gets here. Should have my engine together in a couple weeks and in the truck :woot:

If this were going in my crawling truck I would probably bump up the cam a bit too. I am usually crawling at around 2k and have enough gears to make up for much loss and the higher HP up top would be fun in the mud and snow and dunes we have out here
