With the smaller cam the original poster already has, my manifold will work amazing! I have a patented design with four separate small plenums...
With gear, stall, and smaller carbs they are OK. You also had a lot of cubic inches. My deal is for the guy who doesn't want to put in more...
The carbs have been correct for many different mild builds. On a couple of 383s with large-to-huge roller cams, I had to reduce the size of the...
The carburetor mods are completely different than what you would do to tune a normal tunnel ram. They are related to having four completely...
Not the same thing. The Offy has two plenums with four cylinders each, and no provision for evening out the fuel distribution. My design has...
SlowMoe, I sold one to a guy in Mobile - not sure if that is close to you. If you are interested in talking to him, let me know and I will see if...
Agreed - it may not be bogging at all. You are slamming up against a pretty low stall speed, and your cam is struggling to make any torque at...
A 486HP 355 is not exactly a mild-mannered engine. The dyno graphs started at 3000RPM. If you need to drive on the street, you need something...
Prpmmp, are you absolutely sure about that jet size? Going up 16 sizes on the jets should result in continous black smoke and changing plugs...
The plenums cannot be opened up without wrecking the fuel distribution. Working on another scheme that will trade away some of the bottom end...
Tom, You will never get it really to be responsive with that big single plane top. Google "Real Street Ram" and you will find the cure. It...
With your displacement you should be OK. The Eddy won't lean out on you at higher RPM if tuned properly, but could limit airflow if you are...
Hi - I am the guy who built the Real Street Ram. The 580CFM carbs are there because you need about 300CFM to feed each pair of cylinders....
There are full kits available in my store. You can also buy just the tops and carburetors together, if you already have a base. What kind of...
Attaching a couple of side views
The windows are sized to flow a little more than the carbs do. TR on the street is definitely for the look - but so is everything else on a...
:D Hilarious!
One more note: This is a fully engineered solution. No fooling around with "what should I run for a power valve," "do I have enough pump shot",...
You certainly can make it work - it is just a question of how much funkiness you are willing to live with. With this setup you don't have to trade...
Well, there is quite a bit of work in it even though it looks simple. You cannot do the same thing by correctly sizing the carbs on a normal,...
You can find it by Googling "Real Street Ram". I can't just sell the tops. The carburetors are full-custom all the way through to work with the...
I went with the Weiand because it brings the runners together into two groups that are completely evenly spaced. That makes getting the fuel...
Yeah, the normal ones have all kinds of problems unless you are running above 4000RPM at all times. I have a cross-ram on my '67 Corvette with a...
I think the long runners contribute to the big torque increase everywhere below 4000RPM. Can't really prove it though. The runners are long and...
The big plenum is there to provide you with a big reservoir of mixture at high RPM for the runners to draw from. It actually hurts you a ton at...
Yes, we've done tons of dyno testing. I have filed a patent pending too. Didn't really feel like I could talk about it during the development...
attaching a picture to explain better.
I have been working on a new tunnel ram design. It uses four small plenums instead of one big one. Each cylinder draws through one side of one...
