69 crossram car

[TXZS]

That appears to be a fiberglass hood. It really should have the taller breather and foam breather-to-hood seal. My experience with a crossram and 140 cam is that the power brake booster will not have enough vacuum to work properly if the the pcv valve on the left valve cover and the booster are both plumbed off the intake. I had to vent my valve cover to the atmosphere; don't tell EPA. Of course, this car may have a stock cam. If that is the case, I will bet that it is much more tempermental and slower than with the stock intake, especially with stock exhaust manifolds.
