I know a few people running large displacement small block with no troubles.
I may do something similar (in a Nova).
Here is a write-up on hotrod.com
http://www.hotrod.com/techarticles/e...454/index.html
I love this " both are covered by a two-year or 24,000-mile insurance policy that covers them for up to $4,000 in repairs. But 24,000 miles? Yup--they run on 91 octane and they're designed and built to drive forever."
That is what i'm talking about

I think you mean 434 ?
http://www.ultrastreet.net/ultrastreet.asp
I have the 434 in my 86 that replaced the L98.
I have the 685 hp version.
You might have to change your pullies to the L98 ,I would see if the LT1
pullies would work with the taller valve covers.
I first went with an LT1 and had to use moroso valve covers and have the front step cut to clear the bracket for the LT1 A/C.

I have only seen one person even attempt to use a standard SBC short block with the LT1. You will need to be quite good to pull this one off. The entire front of the block is different between the two so a special timing cover will have to be fabed and I think there may be different cooling passages as well. Now if you just want to scrap the LT1 all together then other then having to rewire the car and a differnt ECM it should be a snap.

You can certainly put a GEN1 motor into an LT1 car, but the best thing to do would be to replace the computer with something like a FAST XFI or Big Stuff GEN3. There is a new computer system in the prototype phase being produced by Arizona Speed and Marine that looks extremely promising as well. If my car wasn't OBDII I would have gone the exact same route...it's actually a pretty easy swap once you get the computer out of the way.

I've read a post a while back that there's a distributor out that has the correct signals to run the CCM. Worst case you could mount the opti on top of a distributor base with an adapter.
You'll need to change the cooling system around too, reversed-cool
I'm pretty sure that's a raised cam design, so the timing cover & chain are different.
But for what it's going to cost, you could drop in a 396 with a blower... or an LS7!

If I use a 396 will I need a fast system? Can I use all the stock parts? I can build one but I do not have a lot of spare time. So dose anyone make a 396 short block late modle. Not a lot of options when talking about heads either. Can you weld a set nonreversed cooling heads to be used on a LT1?

I'm talking about a 396 stoker motor built from the existing block in your car, not a 396 big block.
You could have it built, and noone would be able to tell the difference by looking at it.

re: 454
Is there another rebuild left in the cylinder walls? Can the little M be sleeved?
re: 396 SBC
I have a 3.835" throw crank + .030 over bores = 391cid.
I think going .040 over would yield 396. Is this right?

If you don't have about 20 grand I would just order up a stroker motor.
If you are talking tall block ,no it will not fit.
I went with the short deck 434 for that reason.
I would go to
www.strokermotor.com

"If you coulda done this, like, 15 years ago, you could have cleaned up at the street races sooo big. You read right: 454 cubes in a small-block crate engine, and not an exotic, tall-deck block with a bunch of specialized components, but in a regular ol' Chevy-type package that bolts right into anything that'll swallow a conventional small-block Chevy. It's the new deal from World Products, the same company that previously introduced the 427ci "

I have worked with this company and they are really easy to deal with. Here is the engine page section where the 454 small block is located.

I love it, too.
24K miles is not "forever"...it's about as long as a set of tires last.
Still, big-inch motors look mighty appealing....
