Default LT1 heads

Will a 4 barrell carb bolt up to the lt1 heads? I don't know a thing about them but my brother in law is wanting to use the lt1 heads on an older 350 block and carb it...

Well you can get a carb intake for the LT1 im pretty sure. The carb doesn't bolt up to the heads.........

I would just use sbc heads on a sbc block. To much money to convert lt1 heads on a sbc block and then buy all the sbc parts to adapt to a lt1 heads. THats a no-no in my book

you can have a machine shop drill the heads to accept a conventional sbc intake and you can put your carb on that

The waterjackets are slightly different. If you bolt them on there without welding them up and converting them you will fill the motor up with coolant. They can be converted but whats the point. You can have a set of conventional sbc heads for the cost unless you can do it yourself.

I didn't think running LT1 heads on a SBC block is even possible...let alone having them converted. Now running SBC heads on an LT1 block is a different story.

But what's the point? You can do conventional SBC heads for far cheaper. There is no benefit for attempting such a retrofit.

Last I checked the carb bolted to the intake, not the heads
