Rering 360+268H for DBX11

[DBX11]

Finally took off the stock intake and mounted the used performer from eBay and the edelbrock 1405 from a fellow member and it runs a lot smother with Gobbs of power! Not sure how much seat of the pants hp but I can definitely feel a change it seems to breathe better and the 268h is awesome! Thanks Rick the engine now has about 500 miles and is kick A$$ !! The th400 I rebuilt with my two oldest boys seems to shift up and down with no issues so congrats to me!

So, a refresh with the 268H Comp Cam. One of my favorites for a 304 or 360.

I had to finish this one up before I could get to it though. A 401 with a Cross Ram and dual 600 Holleys. I put the small 280H cam in it and compression is at 9.5:1. All the wrong parts it seems to me to go under a Cross Ram but it is a street car application that just has to look cool. Amazingly enough, it runs like a top and takes all of the carburetion well. It doesn't put out as much power as a Torker with a single 4 barel does but cool it does look.

Do you have the timing set (hooked up to vac) in that sound bite? I have same cam and single 4bbl, but mine sounds like a kitty cat.

I can't remember but I think so. The idle was set pretty low and the mufflers are straight through which is why it might sound a little more aggressive.

Do you have headers or manifolds? Do you have a cat? I have a 268h going through headers, a single 3 inch exhaust, and a borla almost straight through muffler and it is pretty obnoxious.

Stock manifold, no cat 2 1/2

Here is one that I am finishing up for a Jeep SCRAMBLER. It is a 8.5:1 360 with a 268H cam and Torker intake manifold. The 268H is really not a big cam compared to a stock 401 cam. It has more duration and a more narrow LSA.
Stock 401 Cam: 208/210 @ .050" .458" valve lift and 114 LSA
ComCam 268H: 214/214 @ .050" .456" valve lift and 110 LSA
Stock 360 Cam: 196/196 @ .050 .426" valve lift and 110.5 LSA

Just installed the summit racing brand CDI ignition box and it starts faster goes faster and sounds faster!

[DBX11]

Going from the old ignition box to the cdi is a major difference I had already put the big cap and rotor on and the Jeep is utilizing the 268h to the max. Need to take a long drive one day and log in some mpgs. maybe I should look into the broken fuel gauge issue next.

Summit racing cdi box was tested last week took a two hour drive just fine. I did pull the initial timing back a touch along the way tho.

[rang-a-stang]

Did you log MPGs?

[DBX11]

No, the goal was fill up drive 100 miles then fill up again then do the calculations but I never filled back up when I got home. Next time I go out with it tho... I

Fired this up after a bit of sitting around and it rumbles so nice! Going thru it today maybe wash it run it some down the highway. I like the summit cdi box I put in it and I swapped the springs to some heavier inside the 1406. Didn
