    You hit it right on the head John! The dumb bastards left it on the neighbor's porch 5 houses away! Gayleen walked to the closest 3, but she couldn't imagine them blowing it this bad. The neighbor came driving in with it a little while ago, very nice of her.

    Here she is:

    Damn it Malcolm! I've fought with both FedEx and UPS cus they said they "put it on the porch". Stick with it and bitch everyday. They'll dink around but finally make it right. They even wrote me a check one time to reimburse for my frustration.
    Ps. Both times it ended up being that they dropped it off on some distant neighbors porches. Thanks god they were honest and looked our house up. I also returned the uncashed check. What can brown do for you? How bout deliver to the correct freakin house?
    Okay, I'm done...where's the Advil?

    Well, I ordered the Proform from Summit. Fedex says they delivered it today, but I can't find it anywhere! Bastards! I live out in the country so I can't believe anyone drove in here and stole it before I got home.

    Hey Malcolm I use one on my 425 seems to be a decent piece did have a couple little issues with the metering blocks and float bowls mating up (caused one float bowl to seep) but a little filing and it works fine. On the flip side if I had a bigger carb. laying around I probably would have used that. Let me know if you have any more questions about it.

    The wrench for the scoop is at home right?

    On the same note, that's why the Proform's seem to do pretty well on average. Many times they get better and more consistent metering across the rpm range in comparison to old Holley's.

    Sometimes it's the part, sometimes it's the tuner, sometimes it's both.
    you got it cfm but wow proform thats suppose to be junk right,kidding

    we can all agrue over carbs,you do what you think is best and it will be right

    I have used a couple pro-form carbs, they work very well and are usually worth something on the dyno over a standard holley. I would go with the main body. My .02

    Hey Austin,
    Not much progress yet. I need to get the engine out of the 18 and freshen it up to put in the new boat. I can't get near the shop yet though... Too much work to catch up on.

    The 800 is running pretty rich. I could jet it down, but I like the looks of that nifty new main body and they don't seem to make one for the 800s.
