Info on the LS4:

The 5.3L LS4 shares the basic architecture of the 6.0L LS2. This includes an all aluminum block, six-bolt main bearing caps, deep-skirt cylinders, and a structural oil pan. It has the 243 casting LS6 heads with LS1 valve springs, which are good for 6200-6300 rpms.

Engineers had to mount this engine sideways so some changes were made. The crankshaft is shorten by 13 mm overall, 3 mm at the flywheel and 10 mm at the accessory drive. This was done to accommodate a more compact accessory drive. Instead of a 2 belt system there is only 1 long serpentine belt, even with this to save space there is only about 2 inches between the crankshaft pulley and the passenger side wheel well. The water pump is mounted off center with elongated passages to connect to the block (see picture). Also a rear facing intake manifold was designed. To ensure proper oiling during high-g cornering the oil pan has special baffles built in. Since Displacement on Demand uses oil for activation an oil pump with 31% more flow than previous LS2 type oil pumps is used.

Displacement: 325ci (5328cc)

Compression Ratio: 10:1 (premium fuel is recommended)

Bore x Stroke: 3.78" x 3.622" (96mm x 92mm)

Firing Order: 1-8-7-2-6-5-4-3

Horsepower: 303 hp @ 5600 rpm

Torque: 323 lb-ft @ 4400 rpm

Fuel Cut-off: 6100 rpm

It's been flat for a few months, lol. It's bombed, at the moment. Getting it done when I get a job. Deciding between flat with gloss stripes, flat/satin mix, or flat with red pinstriping. The hood isn't painted, just flat cleared carbon fiber.

Thanks for the welcomes. I have Decepticons stuff on my car too. :rofl:

Thanks again everyone.

I love either the blackout or murdered look. I've been pondering the matte black look on my GA.

Thanks again, all. As far as plans, if I can get a decent transmission in it, I'll be turbocharging it. Like this (505 whp)

but with more done, that one just has the kit installed. Porting to intake and exhaust manis and the TB is supposed to net 25 whp N/A and over 40 whp with the turbo.

And I want this cam

AND other little nit-picky things, lol.
