Roots blown lt1 Hey guys i was doing some browsing and found a little info on people using roots blowers on there lt1's, but not many. Just curious why there wasnt more news on these. Also one guy commented on what would need to be done to an old school blower intake to work on the lt1 and he replied
-Cut the water neck off and block the passages
-plug the Dist. hole
-convert bolt pattern (heads or intake..your choice)
-weld in injector bungs, and make custom fuel rails
-go with an LSx style Magnacharger (TB inlet up front....then use an LSx TB)
-Have Magnacharger build a custom jack shaft
-Run your pulley arrangement.
-Make a custom intake setup
If so i might just tinker with this setup and see what we can do. Im not taking this to serious just something to toy with. Any insight would be cool.

What makes more sense is just have SBC heads converted to reverse flow for like 300 - 400 bucks.
This will allow you to use SBC intakes.
Then all you have to do is obviously hood clearance but find a way to route the pulleys.
Basically you'd have to go around the waterpump.
Along the lines of this.

EDIT:
This puts a pulley on the waterpump housing.

It has been done before but if I recall correctly it took several YEARS worth of work and thousands of dollars of trial and error only to have less than impressive results. If the money invested into that project was invested into a more typical setup it would have been a much more impressive animal. IMO, of course.
It was cool to watch though. There's video of it and a build webpage somewhere I think.

Yes. As I said it costs between 300 - 400 to convert SBC heads.
For my engine in my garage I will be converting Pro-Filer 23* heads. Heads are flow 300cfm as cast. AI 200cc flow just under 300cfm and they are fully CNC LT1 heads.
Remember its not all about CFM flow on heads but its just to give you and idea about the heads difference.

Makes more sense to go to a 90s roller vortec 350 block with sbc heads and all the conventional roots blower parts that just bolt on without mods. a good strong distributor
With ignition controller box. Megasquirt to control it. More tuning control with the ms over the lt pcm.
