    Buick roadmaster Lt1

    Had a friend give me a car it was a 94 roadmaster, i think thats the right year. Anyway had a good running lt1 and tranny in it. Just wandering are the buick LT1 any different that those that came in the caprices and stuff. I know there both B-bodys or something like that.

    Would this motor be sutiable for a swap into a blazer? Any help or links would be appreciated, thanks fellas.

    It's the same LT1 that's in the Caprices and the Fleetwoods.
    I put a '94 LT1 from a 9C1 Caprice in my Mazda. It's a great starting point for a swap man. I know there's a few guys with LT1s in Blazers on here.

    should have iron heads, not aluminum.

    personally id get an ls series engine.

    Dunno if that would be worth it to me to put a stock iron head lt1 in.

    id rather have a lt1 wagon then a s-series any day lol


    but yes, it will work in a s-series. But if it runs and your looking to do a EFI swap, id clean it up, sell it and do like superbee said, and buy a LS style engine

    yeah i was looking into them seen it had those kinda heads. Right now ive got the stock 350 in my blazer, just looking for something a lil nicer and maybe efi. I may just do what u all said clean it up and try in sell it.

    What are the lt1's worth neway?

    I know i cant find an ls1 anywere close under 2 grand, but then again i dunno what they go for either.

    FORGET LS1'S!!!

    Your paying for the dang name.

    Shop for a 5.3 or a 6.0 truck motor. They have cast iron and aluminum versions. these motors can be had for cheap. Do some research on these motors, you'll see why it would be dumb to pay for an ls1.

    shit even a 4.8 would run in a 1st gen, but that's almost like putting in a 305 insted of a 350

    the same work with less power

    Be carefull with these, i have found ALOT of roadmasters and the likes with baby lt1's, 4.3L v8's, all parts fit on LT1's, they look identical(waterpump and all fits) but they are a 4.3L baby LT1.


    I snagged most of my parts off of these baby lt1's when i did my swap, all the pulleys and brackets fit.

    is the car in decent shape? If you don't plan on using the LT1 I would just try to sell the car. It's not really worth your time to pull the engine, clean it, and try to sell it. Around here they only go for $1,000-1,500. And that's for engine, tranny, ecu, and harness.

    I love my LT1, but the engine was kind of a PITA to mess with, Im sure the LS engine would be as well. I do think that the LT engine would look cooler

    The LT1s looks great in the blazer. I put one in my 91. It took me a while to figure out stuff and work out the kinks. Plus I've never done an engine swap untill now. I actually just drove it to work today. It's alot fun! I just need to get rear gears. Then I can feel the full power of my corvette LT1!!! I bought my engine, transmission, ECM, wire harness from a place out East. I paid $2,600 delivered to my door step. U can't beat that price. the whole unit had 53k miles on them. I looked inside the motor and it looks like it just came off the assembly line.
