Are you referring to a 402 on an iron 6.0 block? I didn't think the LS6 could be taken much farther than a 383 without being sleeved. I've seen that the iron block is a good base for a budget build, but the extra 100lbs on the front is what holds me back on it since I'm interested in spending a lot of track time with the car.

Thanks for the info. Was just checking out their site - definitely a good resource to help understand what parts combinations yield what power output with a proper tune. I assume their prices include installation. I might go parts shopping referencing their list, have a local shop port match everything, do the install myself, then get the local guys to tune it.

Forged LS7 bottom end? 427 or stroker? Why did you go with LS3 heads/intake? I dismissed the lS7 due to cost, but I'm curious about the details on your build.

I also own a 2009 Zo6 and the 7k redline and M6 gearing is a beast. The LS7 has the torque to pull the M6 gearing quicker than an LS6/M12 and the extra rpm/gear leaves it ahead shift after shift.
I'd like a modded/stout LS7 approaching 7500rpm and M6 gearing. It will be a wicked drive that won't need a blower to excite.

ZZ572 crate motor.....you'll be a little more nose heavy than you already were, but I'm sure adding a blower & additional hardware to an LS6 or the LT4 wouldn't be that much heavier.
Make sure you take the tint off the windows so the C6Z guys can see your middle finger through all the tire smoke as you show 'em what a REAL big block N/A American V8 is all about bahahaha

Yea fully forged... Crank, Rods, Pistons... True LS7 427, Non stroker... LS3 Topend because it was originally built for road racing, LS3 heads make superior TQ in the low and mid range compared to LS7 "More Velocity".. Also at the time there wasnt a lot of options over the faulty LS7 heads. The heads I am running are CNC'd 279cc/67cc/96cc with Del West 2.17 Intake & 1.60 Valves. They flow pretty much the same as a set of LS7 Stage ll Ported. My intake is a Rick Crawford Racing ported LS3, Which he claims outflows a non ported FAST 102 up to 434ci... Im running a modest 11.25:1 CR and make around 538/526 on a stingy mustang dyno. Thats through a RPM Stage 6 4L65 Swap with a 3200 converter on a heavy C6Z 19 Rep with a 27.7" 305/35/19 NT05R... Im also running a very mild "for my cubic inch" Road Race Cam... 233/240 .598 .608 112 lsa... I ran a 10.3 recently on this setup leaving off idle... Currently having a custom cam built by Brian Tooley which is more max effort comparable to his LS7 Stage 4 cam. My cam will be a 243/258 with 30* overlap on a 110+4... should pick up monster power over what i am running now. My goal is a 9.9x NA or better...

Seriously wonder how much heavier/bulkier it'd really be vs. an AL LT4 w/ the SC or if you added aftermarket FI to LSx motor the added hardware/plumbing adds weight & takes up room.
I'd assume you'd need new/lower motor mounts & a different hood w/ a big cowel in the last

show them what a real big block is? You do know the 427 is not a big block correct? nor is it intended to be. A big block is just that, A physically bigger block.... It has nothing to do with Cubic inches lol

Technology/cooling/oiling/AL alloys have come a long way in the last 10 years, let alone the last 30-40 years, but seems to me all along engines known to make reliable BIG power - whether from the factory or from a hotrod shop - tend to be cast iron blocks - still. The 6.2 hellcat, the supra, the shelby mustang 5.4's (until recently), Nelson racing engines, etc. Even dog engines like the GM truck 6.0 run iron block due to the expectation that it'll be "abused" more than if it were in a 1/2 ton - why else would they keep running it & not use a version of either new AL block ecotec??? Why do all boosted diesel motors run iron blocks? Hell diesel runs cooler than gas.
I'd like to see a ZZ572 or 720 powered N/A C5Z....maybe its the PERFECT platform for it since it is so light to begin with. Sure the motor is damn heavy, but like I said what kind of weight are you gaining w/ FI? Saving some weight there, the car is already light, gut whatever else is possible.....if the car ends up gaining a net increase of like 100-150 lbs over the front end w/ a 572 vs. a FI AL small block I think thats acceptable for gaining instantaneous power everywhere
