Straub cam @ 268... Ls7 heads need more exhaust duration. Would place the LSA @ 115

Spec'ed and had the heads made.... may as well do my own cam as well.
268/284 115 LSA 46° of overlap.
Best I can come up with 13.2 with 62 cc heads.
How does the valve events look is my main ?
Got plenty fuel and fire ready is the plan.

Checked email and Bobby asked peak RPM 7800 max. Thought I listed it but O's well. Gave a few reference builds and cam idea.
265/279 111 LSA 830 lift Low Lash solid roller. 50° degrees of overlap with a single plane intake. Changed just that quick from 268 @ .050. for a 7800 peak Let's see what Bobby recommends.
Be back in Houston n less than 5 hrs. Stop by and talk to me brother Zach and see what's up on introducing fuel underneath the 4500 TB (e85 plate kit to cool in coming air) on the Ls3 Super Vic topend setup. Injectors are to low to cool incoming air...Carb thoughts....and paying the Man.
+(Add) $ for ideas. O's well.
Gonna get this cam before the end of August. 100 a wk if need be.

Loving life wish I were Rich.......Hemi,Ford, Ls alll..........the group. I fund self. 2 lsx blocks that R Stuck, Owe $.Sellin? Yes....spoken on the largest bore before... 1 has roller cam bearings filled blk other 1 machined ready.......Stick too the script
Hemi's gen3 on the stand, Coyote Specifically
Got sleeves? Damn!
1 order like uncle Jim, add (+) springs no Leans on parts.......luv when we R a dealer or distributor.
btw they said 840 lift springs add 1.85 ratio, instead of 1.8?

I am looking over this combo and I think 800 hp is going to be hard to obtain. But I can tell you what this thing is really going to need to make it happen. You are going to want to put a good intake on it like the CID. Also a 4.125 bore would make a big difference because of that very large intake valve. But if you must stay with the 408 her is the cam profile I would make you.Low Lash solid roller.263/279 Duration @ .050’’113 lobe separation 109 intake centerline.810’’/.810’’ lift with 1.8 rocker

For 1 given stroke ...give it your best Shot!
Repeat cycle for a given combination. Simple!
Y ask when a ph call is Free!
Cam Motion FTW!
Oh yea, we need spec's 4 both heads and the short blk combinations with ideas, Zach 4 lsxmag and 1 guy's junk and dealings.

Introducing fuel under the TB with a wet plate kit similar to meth injection result were similar to the meth test in the dyno section(from Zach/Oscar when @ Sam). Minimal hp gains +20 or so in best case(i think dumping fuel was involved), but the ability to control the fuel and air ratio entering the runner, besides the injector was a issue . Think using a small pill like a 25 to 50 jet as it wouldn't be dumping fuel rather a mist. = COLD incoming air with the fuel from the injector. Also a continuous, steady system of mist, which would make the intake cold to the touch top 2 bottom. And and easier to tune i would think...mist not dump. Higher compression is a better idea and use of e85.
Kicker...Oscar, Zach's better half & Cnc programmer (wink, wink we do cylinder sleeves) has a used Lsx block with roller cam bearings 4.125 bore , $1k needs a sleeve & small crack.....idk. Big O said he'd sleeve it for a $100 i purchase sleeve. Yet filling the block isn't a option. If the block can be welded i'm game if not too costly? idk. Next major ? I could do that big bore 4.200...idk but would.
Cam and springs for the 7's will be further discussed next wk....Zach has a family reunion this wkend. Oscar added it to my setting up the long block with the ls3 top..Playing on the dyno simulator the cam Bobby recommended on e85 did great...icl liked 111 rather than 109 small stuff.... 7800 strong thru out the rpm curve. Next wk...

I took u off...just meeting great people who've done and can do anything i can or could dream of. Just the way it should be. I'm a very determined person who will....think about it. Kinda pround of who all i've dealt with and what's truely possible. i'm the super avg guy, that's mechanically inclined very much so. Most would have sold out by now, by each part with a goal in mind. I got the time nor will i go broke doing so.
Lsx block?? idk?? Research and call Zach or big O. Filling the block is not a option. Roller cam bearing installation is worth the selling price @ $1k..idk..
Springs and that cam are done Rowdy has to have it. One bill, long block & dyno included. Just paying for assembly with the 1st combo. Paid 4 the short blk work already.
