I have already blown one coolant seal in my new motor and now after another rebuild. I won't pop another. I will see if I can incorporate a similar setup as a 80-90 Z28. It has the plastic piece that grabs air under the car and forces it up on the rad at high speeds. I might have to grab one at the junk yard and try and mod it.

Any one tried it?

 

Not trying to be a jerk but I think that is what the plastic underbody pan is for.

 

yea, get one of those(if your's doesnt already have one), and get a radiator support cover(Goes between the radiator support and front bumper), that should be sufficient...and not to be ***, but coolant seal issues are usually due to either A) Builder error, or B) user error(I.E. driving the car while running hot, if you see your cars temp rising, immediately shut it off and coast of the road, or suffer blown coolant seals)
