No prob..mini ram only has two in front...none in the rear. I ran it on a 408 with no cooling issues. i currently have a cnverted single plane with thre rear ports blocked...no issues.

Just place a large vacuum nipple over each coolant port.

Run the coolant directly from the WP to the heater w/o passing through the TB, i.e. the TB coolant bypass mod.

hi65zo1,
thanks for the tip mate!
but bim not really sure what you mean mate ???
would you have any diagrams mate that you could scetch up please ??
as know coolent is going any where else thru the whole intake accept for the front small passage and then it goes staright thur to the heads port and that is it!
non of the t/b come any where close to the hot coolent you see.
its not like your tipical plenum style t/b thats all mate
thanks

My stock intake base has two coolant ports on each side, to mate up with the two ports on each of the stock #113 heads. However the stock gasket has only a small hole for each rear coolant port; I've read that these are only steam ports to equalize pressure.

I'm not sure how it will work without those steam ports; perhaps someone herein has some experience in this area.
