    Default TR top plate and spacers?

    I'm going to start making a top plate for my edelbrock tr. The plate will be flat 1/2 al plate (no raised area for the carbs to sit on) so i'm going to need some kind of spacer. I did a short search and read a few opinions on spacers but I'm wondering what the thoughts are on my application since a stock top plate for edelbrock basically has spacers built into it. Should I use an open spacer to more resemble a stock top, a shear plate, a 4 hole spacer, or is there a better mouse trap? Carbs are 4150's

    Thanks, Don

    Well here's a link to what I did. http://www.performanceboats.com//sho...ghlight=billet

    IMO the taperd 4 hole spacer design kicked butt in real world response and pull.

    Carnivalride is your intake painted or powder coat. Looks good.

    I MAY HAVE WORDED THAT WRONG, BUT ANTI-REVERSION TUBES (what i've known them to be called) STICK DOWN INTO THE CHAMBER TO CONTROL THE PULSES IN THE MANIFOLD

    Thanks, it's painted, smoothed it up and recontoured the flanges that meet the heads. Shoot it with ecthing primer, then an acrylic urathane (PPG Concept).

    Haven't heard of them either. I've heard of spacers and Edelbrock used to make an intake with anti-reversion step. Guess I've got more to learn.

    Post away no need to be embarassed. I was going to put a twist on these but it caused some interference with the mount hole so I took the easy way out and just ran them as you see them.

    Thanks I was thinking doing something with mine. It's a single Dom. It's just raw now.

    I am building one similar to that for my Dart tunnel ram. It only has 1/4 rise and the rest extends down into the plenum, and the carbs mount at a slight angle to better line up over the ports. Same basic concept though.
