    If your doing a 383, Id just get an aftermarket crank. And doing so, Id just get a whole rotating assembly as a set.

    That link that Catching Second posted has some pretty good prices for rotating assemblies.

    The only thing I've heard of Crower is there cams. I honestly didn't know they made bottom end stuff.

    H rods and a variety of cranks too.

    They don't make their own pistons but used to give you a choice of either Ross or JE.

    Probably about 3 times the cost of SCAT ( don't quote me on that)but tend to survive bearing failures better than a SCAT from what I have seen and heard.

    By the way my plans have slightly changed. The blower kit I was going to get from a friend has fallen through and he wants to keep it for himself. So I think I am going to build my motor for a nitrous setup now. What do you guys recommend for pistons/rods and compression ratio? I am still planning on the 383 crank. How much nitrous can I run through this motor?

    My opinion is to wait until you are sure what you want

    I didnt think summit would price match on internet sales? Good to hear.

    Good internals will take 250+ of nitrous. If your going hardcore with it, might wanna look into a 2 stage set up, like 100/150 shot.

    Or even a progressive controller.

    If you look in the left side of the pic you can see one of the first compucar 2 stages ever 250 total = 100 + 150.

    I have 2 regulators (one for high and one for low) and a dedicated holly blue pump.

    I have never used a progressive controller but have heard varying opinions on cycling larger solenoids.

    Don't take this wrong, I love nitrous for street, haven't quite conivinced myself its the most economical option for the track yet, certainly doesn't have the curb appeal of a roots style blower poking through the hood.

    Check the price of nitrous in your area - Its $4 a pound here at Jegs.

    There are also increasing laws coming into play on Nitrous since F&F idiots. PA you can't have the line connected, some cops are even ticketing the fake nitrous bottle subwoofers. And it isn't going to get better.

    Ok that definitely helps. I'm just trying to look in the right direction before I regret a decision. The nitrous shot will be moderate around 100. Will I still need forged pistons/rods for this? Can I get away with regular rods and forged pistons? What kinda compression is ideal for a nitrous setup?

    here in FL they aren't doing anything about nitrous, and last time i filled a bottle about a year ago it was $20-30 to fill a regular size bottle

    My dad had a set of the afr's and they burned a quart every....3 or 500 miles? Anyways, we tried everything we could think of and finally we just had to let them go for 500 bux. I sold them to a kid in my class and him and his dad found out the oil drain hole was machined just a little too high, the the oil didnt drain out enough. Probably a 1-10000 chance but ya never know. They company wasnt too cooperative either.

    And dont ask the parts stores for a 2.8 frame mount, you;ll be asking all day, just ask for a 2.8 motor mount, thats just how it is...
