68 twin turbo dart project.

Logs are ugly and dont make big power like I want. I have plenty of room for the down pipes no matter what kind of header I use. I am going to intercool it. I used to have a large front mount air to air intercooler and it worked okay but I am trying to make as much as I can from my combo. Here is the pic of one of two Spearco intercoolers that I will be using. They came off my buddies 7 second Camaro with 30 pounds of boost and 40 degree intake temps so I think they should work fine. I am going to cut off the tanks and merge the two intercoolers together.


My understanding was that the only noticeable power gains over a log manifold were with equal length runners, but more power was gained with getting the exhaust out quicker, as not to heat soak everything under the hood.

What liquid do you plan on using to for your intercooler?
