    If this isn't a complete LT1 engine I would stay away from it. It is basically a Gen 1 engine on the outside but everything else is LT1 reverse cooling specific. Your biggest hurdle that I can see is the opti. I've seen people convert them to distributors but why go through the hassle. Also, make sure it's a 5.7 litre. There were some "baby" LT1s that had much smaller displacement. If you have one of those they're not worth anything really.

    If it were me and my money, I would go find some Gen 1 engine and rebuild it. Much easier and much cheaper. Take it from someone that has built a 383 stroked LT1. If I didn't already have everything from a donor car, I never would've built it.

    BTW Regular Camaro headers will fit it. The LT1 is D-port and the "regular" small block is round port. They are different, but, they will work just fine.

    Get a 1987 or later block out of an F-body (L98 in the Firebird, Camaro), B-body (LO5 in the Caprice, Roadmaster) or a Y-body (L98 in the Corvette) and you've got your roller stuff.

    Or you can get lucky, as I did, and get an LO5 out of a 1987 or newer truck which has the roller cam provisions. It's a rare occurrence, but it happens. The casting number is 14093638

    The Vortec heads were designed from the cast iron LT1 heads.

    If you can find an L31 out of a 1996 or newer GM truck, it's a roller cam block and will already have the Vortec heads.

    L31 applications:

    * 1996-2003 Chevrolet Express/GMC Savana full-size vans
    * 1996-1998 Chevrolet/GMC C/K full-size trucks
    * 1996-1999 Chevrolet Suburban/GMC Suburban full-size long-wheelbase SUVs
    * 1996-1999 Chevrolet Tahoe/GMC Yukon full-size short-wheelbase SUVs
    * 1999-2000 Cadillac Escalade

    TBI L31 applications

    * 1996 G-series Vans over 8,500 GVW w/ 4L80E

    if you've got tons of money, the LT1 (assuming it's the 5.7L) is a heck of an engine. they're amazingly fun off the line (though i'd still make it fuel injected).

    if you don't, i'd do like they said...go vortec 5.7L. i've got a 75 block with vortecs and a few extra goodies and it'll smoke a 2.41 peg leg for 30+ yards. gotta get those 3.23s and some posi in...blah

    It can be done, but, it will be $$$. Like I said before, if you don't have everything it'll cost more than just doing a late model vortec.

    You can use a LT1 with a regular SBC distributor . You can keep the carb also the intake has both carb patterns. If you pull the opti off GM sells a cover or make you own . You can run the stock water pump or go electric water pump . If going electric a double roller timing chain can be used , just have to grind the timing cover for clearance.
