All stock blower and intercooler bricks.

GM stuff is the best but I'm tainted.

It amazes me the power and reliability these factory GM peices provide. I'm in the middle of assembling an LS7 for my Mustang, some of the parts in that engine are so far beyond anything the aftermarket had just a few years ago. Love the build Mark. Ron

Yep stock stuff

Stock LS7/9 headers
LS7 block with ARP studs and piston oil squiter added
Stock LS9 unported heads with better exhaust valves
Stock LS9 blower with new inlet and pulley ratio
Callies crank less heavy metal to balance
Oliver 6.125 Rods
Lingenfelter 6 bolt flywheel for Callies crank to take LS9 clutch
Diamond brand coated pistons

This is the best engine I have ever had.

I can't wait to get it done and to the track.

I don't think I can make Road America but I should be at Putnum Park.

I have to ask, GM didn't think that block was sufficient for the LS9, why do you?

[Stielow]

Working on a custom blower cover.

I want to remove the "LS9" on the cover and replace it with "7.0 L".

Still want to make it look OE

Here is a CAD screen shot

Nice cover

[6spdcamaro]

i used a wood router and machined the "GTO" raised letters off of my engine covers. I sanded it and painted them and they look good as new. Just move quickly or it bakes the plastic

Cant wait to see you drive this around the track...
Ty for updating Mark and the 7.0L Supercharged is as cool as it gets

The LS7 block will handle it. The 6.2 liter has a shorter stroke and you can fit the oil squirters easier. The non-siamesed bores are better for cooling. My engine would never live thru a GM's durability tests and meet all the validation requirements. But I'm not expecting this engine to meet emissions and 100,000 mile powertrain warranty. The bigger bore and stroke make it harder to balance all the issues listed before. We are also pushing the blower harder than what it was validated to. But I guarantee this will last much longer than most "aftermarket" stuff.

I want to make big power for a hot rod. I'm in uncharted waters for a road race engine. If I can keep it cooled it will work. Jackass had no issues with cooling so I'm following that combo and added about 30% more cooling capacity.
