20" HREs all around, IRS rear in a custom frame. I just see your car as a a true protourer. A comfortable smooth street car that is still very competent on a track but not a track first focus.

Sure the supercharged motor is heavier but it's not like you went on a weight savings binge anywhere else. Why not have smooooth power and good milage for those road trips with a bunch of on demand low end grunt.

700hp it will still be a missile

Makes you want to rethink building the 'iron lung' doesn't it?

I chose the 427/440 option because the sound of that thing at WOT will bring a tear to the eye of God himself.

Very sweet setup Greg..I don't know how I missed those pics/specs. Cant beat the supercharger power and looks with ability to keep drive-ability, mileage and have 700 HP.

I GUESS you know what my vote is :-)

The blown 376 will fill your Chevelle's cavernous engine bay so nicely. And they are very well built engines.

Nope

Just reminds me you need a supercharger on an LS to make the same hp

I do like your name for my little daily driver motor "Iron Lung"

Not really, here is a 700Hp NA LS7 that runs on pump gas.

If I recall yours used racing fuel to achieve those numbers. Actually, there was a 427 side oiler that dyno tested before my LS3 418 with Harrop TVS2300. I used 93 octane pump gas and my Hp numbers were much higher and with a peak torque of 787 ft/lbs at 3900.

Never tested with racing fuel..

Guys, could someone elaborate on these two engine builders please. PM me if there's something you don't want to say in the thread. But, I need to know real world facts. The two engine builders are ERL Performance and Golen High Performance Engines. I like what the guys at ERL are talking about and I've heard a few things about Golen. But, what shop hasn't had a bad experience or two? I know there are alot of other reputable builders out there, trust me, I've spoken to just about all of them at least twice.

ERL performance primary builds the superdeck, but it is mainly used for racing engines. One of those engines (Ohio Boys) on ERL performance website was built by Kurt Urban. Here is a article on that engine. http://www.gmhightechperformance.com...s/viewall.html

Kurt Urban offered me advice on building my engine, and he did get me Rich Gala from the former W2W to tune my engine. At that time, Kurt wasn't willing to build an engine, so I relied at my local engine builder to build the engine.

I am not sure your hp goals, but if you are looking for an LS Engine with a TVS 2300 then I recommend the following engine builders.

Kurt Urban http://www.kurturbanperformance.com/
Brain Thompson http://www.thomsonautomotive.com/lsengines.html
http://www.wegnerautomotive.com/ Wegner Motorsports built an Ls3 with 914 hp. There is a video on youtube of it. Also Casey Wegner builds the accessory pulley setup for both Magnacharger TVS 2300 and Harrop TVS 2300.

Never heard much about Golen.

Jeff, funny you mentioned Thomson. I just spoke with them on Friday.

A great bunch of guys. But, the thing is, I already have an LS7 block that needs to be resleeved and I wanted to get it resleeved to aid in the longer stroke. The stock sleeves aren't capable of stroking to 454, etc. ERL is willing to take my block as a core and sell me one of their ductile iron, resleeved LS7 441's for a nice price. Now, I know I'm not gonna be racing and yes I can do an LS3, etc. These are just thoughts running through my head right now. I'm still debating on superchrged vs. naturally aspirated. An LS3 is still an option, but so is a blown LS7.
