My LS7 442 Build
So for the last few months, I've been savin my pennies, picking 'em up when I see 'em on the ground and living off of bread and water, with a ramen noodle here 'n there. Sometimes I'll splurge on beans and rice and tortillas. I've been researchin the living hell out of stuff for-fkn-ever now, talkin auto guru's ears off, and have finally came up with a pretty solid parts / build list which I've been gathering little by little. My plan right now is to get the short block together and use my current stock cube H/C/I/E combo, get it back on the road and then begin round after round of upgrade, continue researching, talk more ears off and tediously document and dyno every change and upgrade, as well as tracking the car.
My goal is to leave absolutely no stone unturned, extract every singe last feasible, conceivable, imaginable ounce of horsepower from this thing while still being able to cruise the hell out of this thing. It'll get drivin to and from the track, Laredo, RGV, Houston, work, all over the damn place. I'm building one of the baddest, most unique NA / N2O LS7's out there. NA, we're shooting for a LEGIT 650+ rwhp from this thing, which I thing is doable, with the backing and support from my wife and Volatile Performance.
Here's what I have so far.
-Wiseco forged pistons, which will be fully coated.
-Callies Dragon Slayer 4.125 stroke crank
-Callies Billet rods
-ARP main studs
-Monster twin disc clutch rated for 1,000+ hp
The short block is pretty much ready to go back together, though I may send the block out to be sleeved first. I don't need to, but I kind of figure why not at this point lol. Motor will end up at 442ci. Planning on high SC / DC on 93 with race fuel for the nitrous stand alone.
Future plans are :
-Dailey billet 4 stage dry sump
-F.A.S.T. 102 combo
-Custom fuel system : when needed
-Induction Solutions Direct Port
-Custom N2O standalone tank
-FRH ported LS7 heads. From the research I've done so far, people I've talked to, I haven't seen any stellar, super amazing, gotta fkn have 'em! results from builds that have used MAST or All Pro heads.
-Stronger DS, MGW, trans / diff bracing, motor / trans mounts / Penske coil overs
-Custom 6pt cage / Kirkeys / 'chute
-Meziere ele. water pump
-I'm also going to look into makin a custom ovalized side exit exhaust like CMS did, that'll exit under the rear break duct thru the rocker panel.
That's about all I can think to post for now. Here's some pictures of the rods, and a mockup of the engine I did in the bedroom. I'll get pics of the crank later, along with more updates as things progress.

I'm pretty sure I'm gonna send the heads to Frankenstein, but I'll talk to Greg Good also.
Other than that, I'm on the hunt for a FAST 102mm and I have some parts from my previous for sale here in these threads.

I got the engine back from the machine shop last week. My LS7 heads are still at Frankenstein Racing getting repaired, cnc ported, and machined for Crower shaft rockers! FRH is also porting and port matching my FAST 102mm. I should have them back by next weekend.
I need to get a set of Kooks headers for the round port exhaust, instead of the factory "D" shape. So I'm selling my Kooks "D" headers.
Compression will be 12.3 - 12.4. ID850's will light the fire, fueled a Walbro 450 or the Aeromotive A1000 drop in kit they make, with plans for flex fuel 93oct / E85.
Martin Smallwood @ Tick Performance will be specing out the solid roller cam. At his request FRH is installing PAC 1208X springs and Ti hardware, which are good for .750 lift. I think I'll be calling this a 3/4 cam haha. I'll be getting some fat 'ole pushrods from Trend and Morel solid lifters.
I'm not planning on having the car back on the road till after TX2K / April.
In the meantime I've got a bunch of small things planned. I'm cleaning and painting all the suspension cause I hate dirty corrosion, and I'll also be correcting the paint thanks to my background in paint and body work.
Here's a few pictures for your viewing pleasure



I'm curious as to what solid roller lifters you went with.
I'm in a similar build but with an ls3 '11 grand sport hoping for 540 RWH N-A with solid lifter cam of course, stock cubes stock block..
Have fun and enjoy your build.

Glad to see the cam came in smoothly! Looks great!
This cam is actually IMO fairly mild for a solid roller camshaft. Lash takes away a large amount of low lift duration. Consequently the majority of the overlap period in street/strip camshafts occurs at low lift.
The cam should drive excellently, but have a mean idle at the same time...just what Malachi wanted.
With how well the heads flow above .600" lift, this cam will be able to take advantage of every bit of that and really make some great power on the rollers. I expect a 6500-6700rpm power peak and for it to carry 7200-7400rpm.
Had I finished this build sooner, I know it wouldn't have been the beast I'm building it to be now.
