The car developed a radiator leak on the way to SEMA. I chose not to try putting goo in the radiator. If it fixed it I would have to flush it out. If it did not work I still would need to fix it and flush it out.

The safest thing to do was bow out and fix it correctly.

Mark,

First of all Love your cars! Hope to see a DETAILED build on this car!

I am an the midst of installing an LT4 in a 71 Firebird. I see you went vacuum brake booster for the brakes. The instructions that came with the LT4 said use a vacuum pump as using a vacuum brake booster will have issues under boost?

What did you do? Pump or no Pump? If you used a pump which one did you use?

Thanks,
Stan

Mark, or anyone else following along. Thoughts on PCV plumbing for a dry sump LT4?

I see this.



Earlier in this thread there was a pic of what appeared to be -10? lines on the valve covers.

From what I can gather, GM ran a line from the air intake tube and a line from each valve cover to the dry sump tank. Is the Pro Vent on Gunner in line between the valve cover and tank or intake and tank?

......or is the Pro Vent the fresh air intake/blow off for the PCV system period.

I ran 2 -8 line off the valve covers and tee them together to a -10 line. That line goes to the top of the Peterson dry sump tank. Then a hose (I think 3/4) comes off the top of the tank to the Pro Vent 100 (3931070793). Then a -10 line comes off the Pro Vent to the inlet tube behind the MAF sensor.

I have experimented with the other Pro Vent 100 part numbers and that is the one that has worked for me.

The Pro Vent has a drain with a one way check valve that drains back into the dry sump tank. (I need to look up the part number it is a Mann &Hummel part)

The dry sump tank has been modified to add 4 extra quarts. This is so the oil level is not as critical because you are checking it with a dip stick.

I know it is a expensive system. But it works great. I’ve done this on 3 cars so far and I really like it. Keep the engine bay oil free and keeps the engine happy.

Hope this helps

The instructions are wrong. You don’t need a vacuum pump. The vacuum pump is for cold start on the stock car. So don’t park you car on a hill and deplete your booster and take off quickly on a 0 degree day and you will be fine....

It is Engineeringly correct yes. Do you have to have it with a stock LT4 with out cats. No.
