    If im not mistaken, i believe that ive got pirelli scorpion zero 235's. Exactly how'd you drop it? Replaced the bags with shocks and shorter springs out back? And to answer your previous question, they're 22x9.5

    The billet grilles for the fleetwood dont come cheap, but they look clean as hell. I'm just ready to get my ride back on the block!

    By the way, nearly got 290,000 miles off of the previous LT1!
    First off, I just wanted to say "hello" to everyone here, as I'm new and this is my first post.

    I actually just found out that the 1994-1996 Fleetwoods had LT1s yesterday. Being a huge fan of the LT1, I can't believe I didn't know this tidbit of information!

    Anyway, I own a 1994 B4C Camaro, which has the LT1. I'm sure that both motors are the same, aside from the aluminum heads on the LT1s on the Corvettes, and the F-bodies. Also, the Corvettes have 4-bolt mains, while the F-bodies have 2-bolt mains. I believe the Impala SS/Caprice LT1 is also a 2-bolt main block. I'm not sure about the Cadillac's LT1.

    To answer your question, I can make some suggestions on cams and such for you. I've got an LT4 Hot Cam setup in my closet, which includes 1.6 roller rocker arms, LT4 valvesprings, etc. I got my setup through www.gmpartsdirect.com for approximately $505 including S&H. From what I understand, this was a VERY GOOD price.

    I don't know how much power you are looking for, or what you are using the car for, but the LT4 Hot Cam setup will net you around 330-340rwhp, from what I understand. This setup will probably make about 380-400hp at the crank, with headers, exhaust, intake, and other basic bolt-ons.

    If you want to go larger, and emissions aren't an issue for you, you could go with the Comp Cams 306 cam, but it's a pretty wild cam. Don't even consider the CC305, as it isn't much better than the LT4 Hot Cam.

    As for computer tuning, I would highly recommend contacting Bryan at www.pcmforless.com. I just got a custom tune from Bryan, and his work is exemplary. His tuning really woke my car up, and I paid $114 including S&H of my PCM. Do not even waste your money on a $350 Hypertech Power Programmer. Bryan's tuning is GREAT. The difference in the performance of my car was night and day with the tuning. My car idles smoother, has more power and is smoother throughout the rpm range, has corrected a slight stumble while the engine is under load, improved the gas mileage, and the throttle response is quicker. I can't say enough good things about www.pcmforless.com.

    You may also want to consider a higher stall converter for your car, approximately a 2400-2700rpm stall, a shift kit, and a set of higher ratio gears than stock. I would recommend going with a 3.42 gear, which is a stock F-body 6spd gear, but will be a happy medium between the stock 2.56 (?) stock gears in your car, and 3.73s. A lot of people have found the 3.73 gearing to be a bit much in a car that is driven on the highway. If you do decide to get a stall converter, I also HIGHLY recommend a transmission cooler. B&M sells these for around $60, and it's money well spent. I went with a 24000gvw on my car, which will keep the tranny plenty cool.

    I hope this helps, my friend.

    Re: Fleetwood LT1

    I definitely will check out the pics of his car! Does the Cadillac come with the Corvette's LT1 (4 bolt main block), or the Fbody's LT1 (w bolt main block) from the factory?

    Either way, the LT1 is a fantastic engine, save for the optispark. I've had nothing but good luck with my LT1, aside from the optispark. I've got over 152,000 miles on mine, and no ticks, no tocks, no burning oil, etc. And no, I don't use synthetics. The LT1 is just a great engine.
