Well I have like $7k into an LS motor going into my truck that still has more that has to be done to it. I hope to have that in the truck before winter hits. Especially since I plan to use it to tow with.Great point. As previously pointed out on my posts, my centrifugal set up has some pretty ugly overhang too. The LS motors allow for a much stronger supercharger set up; that is for sure. Add in the difficulty of tuning a supercharged LT1, and what you are going to spend on forged internals, fuel injectors, transmission upgrades, etc, etc, and it seems chasing a big horsepower, supercharged LT1 set up is a dreamers folly.

So if there is a Gen 1 SB blower intake that will bolt up to the LT1 I would greatly like to know where to get it. I was talking to the guy at the dealership near me (Berger is known nationally for putting out powerful cars), and we found the dual plane carb intake that they still sell. I tell you, looking at the variety of engines they had sitting there it would be hard not to just grab one of those and stick it in. They had a Z06 engine with blower on it... $15k.. I will have that in probbaly both of my engines combined or close to it by the time they get done. But it only put out about 650hp and about the same ft/lbs. Only he says... He did see where a couple people made their own intakes for the blowers. When I have a home shop I could probably do something similar if I have to. Although my cutting and welding skills aren't all that.
There are some 1000 hp lt1's out there... I read an article where they compared this LT1 to the current crop of LS1 and the article showed that they were getting more power per CI on the LT1 due to the higher compression, reverse flow coolant and some other things. So I guess I am not scared to upgrade this engine and get some power out of it.. worst case I will have this old 5.3 out of my truck...
