heat exchanger mounted nicely mounted the pump on the right side and mounted my new smaller washer fluid tank on the right

I’ve read other posts that those things don’t fit under a stock hood without milling the top. What’s your solution?

at least in my situation I can close the hood completely with the supercharger installed but it is extremely close and will surely rub with the engine running. so I will need to make clearance somehow. thinking about just nicely cutting the inner structure of the hood. those fins are very small but maybe i will look into getting my friend to mill down the top.

Milling the fins is what another member did for clearance. Seemed to work well.

My brand new gm supercharger lid leaked as soon as I put coolant in it at the quick connect fittings. After a week of trying to make something work, I got 12 an fittings welded to the lid and got nice 90 degree fittings. i also got my custom intake welded up its made from a 90 and 60 degree bend of 4 inch tube . i aslo realized the pins are different for my new and stock MAF sensor so i had to de-pin and swap 2 wires i also installed summit racing spark plug wire heat socks

re mounted my power steering reservoir mounted my oil catch can the only thing im not completely happy with is my intercooler fill neck location. eventually i might at a intercooler coolant tank. i have a appointment to get it tuned on feb27 at complete street performance in west chester PA

They are not that much more than used one when you are buying from www.gmpartswarehouse.com. I am a GM technician and they even beat my employee prices! I have most things collected based on "Silversled"'s great write up of his LSA install. I still have a few big things to figure out like
What Intake/air cleaner to use?
What injectors to buy?
and Why does everyone seem to install LSA valve covers?

Any help/advice would be appreciated!
I plan to post pictures and prices I paid to help others

17mwolfe,
Nice work!
The smallest injector I'd run (and did run) were the LSA GM injectors. On a stock blower, with stock pulleys and ZL1 fuel pump controller programming, the injector duty cycles were around 80% which is for all intents and purposes maxed.

As for the LSA valve covers, I chose to run them for the following reasons:
1) They look nicer IMHO
2) It allowed me to run the stock ZL1 PCV setup to look stock
3) I got rid of the ugly coil bracket (which needs to be redrilled to mount lower)
4) It has a nicer flatter land for welding or press fitting an AN style vent fitting later.
