i read a article in a magizine about a 454 small block. dont think it would like the street much. possible a slight overheating problem. hey you could run it on alcohol!!!!

I am doing 2 408 inch LT1s right now and they work pretty well.

I don't think DART makes anything for the LT1. TFS has some nice LT1 heads that you can actually get fairly easily and they are decent castings for porting as well. You can "make" LT1 heads out of regular castings as well but I prefer to use ones setup from the get go with all their heat treat still in them.

I think the biggest you can go on an LTX block is around 408-409 cubic inches..

LME does a Dart head conversion for the LT1, they are a site sponsor.

People who can type in readable English can have more cubic inches.

It's true.

Probably a 4.060 bore and the 4,000 crank.

There used to be a vette in Houston that supposedly had a 421ci LT1 in it. Of course the guy also owned a shop that was known for its scams.

Yeah, also there is almost no room for a piston any more at that stroke length and block size. There may be technology soon to allow a little more stroke but it's not here yet.
