Quick Question i found this site where the sell long block motors. http://www.golenengineservice.com/html/lt1_lt4.html
Now there is a 350 lt1 long block pushing 360hpand a 383 400hp, will these motors bolt directly into the stock car without modifying the car,i dont want to have to getbigger radator ect.I just want to take the old lt1 motor out and dropthe newand rebolt everything,i know u will have to get it pcm tuned but will that all it will have to take?

 

It looks to me like its just an lt1 with some different internals for more hp. Now I could be wrong, but I'd think it would all bolt right up... However, I wonder if you'll need a different distributor. 93 and 94 lt1s were different from the 95-97 lt1 distributor. They would probably use the later one from 95-97, but I dunno.Maybe you can specify. If you go to this link you can ask them questions.

If you use the original front cover the original distributor will fit fine.

 

pete my car is a 97 lt1

 

Use the front cover and all acessories from your current engine, including the vented optisparkand everything will work out, make sure the cam has the right size pin for 96/97 engine. The earlier cams have shorter pins & won't work with your distributor.

 

While we're on this subject... My 97 is almost at 150k on the odometer. It still runs strong and is very reliable, but it seems to me that I should be thinking of a rebuild soon. I have a old gen 400 block sitting in the garage. Is it possible to swap the F.I. setup from the LT1 and use it on the 400? I was going to turn it into a 406 for an older camaro, but it now has an LS1 in it.

It would be easier to rebuild the LT1, I'm sure. But, it's my daily driver (obviously) and would like to have my down time limited. I'm guessing that the opti-spark/camshaft aregoing to kill the deal.
