Great camshaft. It'll thump like a ***** in heat in a 318. The weiand is head and shoulders above the performer.
 
No, the performer is a better manifold...... On a small block.

here's the deal.

I have built four different smallblocks with that cam.

One, IMO, it is too big for the manifold, and too big for stock compression. You want that cam to run, and not just "sound" like a runner, you need a real 9-1. Sure, the stick will help, but, a dog is a dog.

Also, there is a huge difference between a 318 and a 360.

You WILL need to prep the heads for that cam, grind the guides down for the lift, etc.

To give you a taste, this is a 390" small block with that cam, 9-1 compression.

PS, I went smaller solid cam, not made for the big lifters, less lift, and gained power, not top end power, but useable power, and, MPG. I couldn't get a set of hyd lifters to hold up longer than 20K with that lunati. You have to think though, my engine runs 4000RPM+ a lot, at WOT. Doesn't sound like much, but a hard working truck engine is a different breed.

What kinda muffler was on the car in the video
 
I know this is a 340 but it has a deeper sound then the video you posted.dodgetkboy78

Who are you talking to stroker......


The vid I posted, is a truck, it has 3" hooker aerochambers and tail pipes, and 2 1/2" from the muffler to the collectors.

You have to understand, sound isn't what makes an engine, and most people run flowmasters, which, I find funny, because, flowmasters, don't flow..... (but like COMP CAMS, they spend a hell of a lot on advertizing)

Are you building a 318 or a 360? (I think I asked that already)
 
I guess I'm asking, cuz' when I was young, I put a lot of big cams in stock engines, and got, well..... weak engines. All technical advice aside, IF you had a stock 318, and you put the 8007 or the performer on it, and that cam, if you didn't have a disaster, you would have an engine that didn't run as strong as if you had've put a 260/260 comp in it.
 
Well a 318 (for now) I want a cam that big enough to sound like you have something but still get the best performance you can out of a mostly stock 318 with a 4bbr.
 
YUp..... Won't chop as much though, no extra cost ISKY will grind it at 106lc for ya. It will "sound" like that lunati, and make more low end TQ, since that is what you are really wanting........
 
Also what if I used 1.6 rocker arms would that mean I could run like a 450 lift cam (rated with 1.5 arms) and get good sound and performance.
 
You have to do work on your valveguides to do that, or at least I would........ Your retainers will hit your seals, or worse.

Do yourself a favor, upgrade your stock 318 nicely, then, build a real engine later, that builds more power than noise.

Yeah the 318 is for now and I am saving up for a 340/360 build

Don't sell Isky Cams short. Ed and his company were grinding cams and designing components long before the Comp Cam kids were even born. Isky is a true pioneer in performance cams and components. Here's a interesting history lesson to read: http://www.iskycams.com/history.html I agree with the guys. If you put a cam in your 318 that idles like a funny car you will be hugely disappointed with the performance. I imagine you have a automatic trans. With a cam that big you had better have a 2500 rpm stall converter or it won't even idle in gear. And big cams need the whole package, compression, intake/carb, ignition, headers, converter, and rear gears to make it all work as a package. If the bigger cube engines in the videos sound good, multiply the "chop" by another third with a 318. Big cubes, big cam. Small cubes, small cam. tmm
 
That's not true with that 340. Since it has the same stroke as a 318, it will sound VERY similar. The stroke has a lot to do with that, yet nobody ever really talks about it much.
 
Yep. That cam would be happy in a 360 with other parts to go with it.
 
One more ?

What this motor worth the guy is taking offers

What ad says



I've got a short block that i built up for a project car, but ended up going a different direction. I started with a 75 or 6 model truck engine. Got the block vatted and bored .30. Installed TRW forged pistons onto the factory rods (which checked out fine). New timing chain/gears. Installed a mild street lunati cam. Nothing crazy. I was planning to make it a reliable street cruiser with a little lope to it. All new bearings (sealed power) the factory crank checked out fine. It's a complete shortblock, minus oilpan/pump/lifters and top end stuff. It's torqued,painted hemi orange, even coated the valley for better oil flow. I'm taking offers for it, trades considered also.

I like the isky brand cams. I would go with the 264mega cam ground on a 106lc. it would give a nice lope on a low compression 318. we had this cam in a 273 9 to 1 and it had a pretty rough idle around 12.5 inches of vacuum. Probably sound similar in a low compression 318. Had alot of midrange.
 
To say " I would go with this Cam" without a plan,is just plain silly.
It is the sum of " ALL" parts combined that select a cam.
Untill you come up with a plan, your shooting darts blind folded.
 
Well...say what yall want but here's my TRUCK engine.

.030 over 318
Magnum heads-unported
Blueprint 9.3:1 with stock replacement 4 eyebrow 318 pistons
Hughes 1110 springs and matchin retainers
This cam: http://www.summitracing.com/parts/LUN-60403/
This intake (but unpolished): http://www.summitracing.com/parts/PFS-55025/
Long tube headers
800 Thermoquad

You build what you want to, but my **** is gonna sound badass and run the same way for a 318 in a old truck. And before you say it'll have no bottom like a idiot, consider the A833 OD behind it with a 3.09 first gear. Couple that with the 3.55s in the back and that's a 10.96:1 first gear. You can come close to that with a 904 that has the 2.74 low gear set. You can build your engine however you want to...but it will run much better as a complete matched package.

A wise statement indeed.
