I REALLY want to put a 1900 on my LT1...but they don't make one. If I can make, or have made, an adapter (LS1 intake mounting pattern to LT1 heads) would I be able to run the MP 1900? I think a 355 / 383 LT1 with the 1900 would be an absolute monster, plus there is a cool factor to it as well.

 

LT1 I think is the has the bolt pattern (except middle ones) as a SBC. Edelbrock has a SBC kit.
ls1 intake will never fit lt1 application, ports are all wrong.

 

Ya, you would have to have a custom tub made for the supercharger. It would be possible, but not at all cheep unless your REALLY good with a tig,

 

I have a manifold I can sell you. You would need to fabricate some of the parts to make it work, including an intercooler.

screw that edlebrock garbage.

 

Well, I am a noob in the FI world...so bear with me. The way I understand it, the intercoolerbolts directly to the heads, right? If this is the case then an 1/2" adapter plate with countersunk screws should enable me to mount an LS1 bolt pattern blower to the LT1 heads. I am not trying to say you guys are wrong, just looking for some clarification as to what would have to be done. If anyone has any pics that might clear this up for me, that'd be great.

 

The lt1 intake ports are no where close to lining up. Its not a bolt pattern thing its a complete diffent engine thing.
So you will need a new lower intake built. Like mentioned early, your lt1 has the same port config as old school SBC. The bolts are at a different angle but thats an easy one. Find a set up to fit that and your on your way. I thought EDL was using magi stuff, maybe wrong.

 

A picture for clarification.

SBC with LT1 Gaskets

 

Thats workable. Thanks for the pics.

I don't know if it's doable or not. But I'd imagine using the base off of the SBC system and the rest for the LSX system. Just fill in the Holes on the base and re-drill them to fit the LT1.
I just don't know that the base bolts up to the LSX S/C or not.

 

So, with a little head bolt location maneuvering, I can bolt a roots blower for an SBC right to the LT1 heads? Now, do they make SBC roots style for EFI?
