7AGE Build

[Dave W]

I agree with Ivan, look at ducting to the oil cooler, but also is there and unrestrictive air flow path exiting from the cooler. You may also have other oiling issues. Do you have the stock splash shield, look at a diffuser screen and crank scraper and do not over fill the sump, which also interduces more air into the oil. As for the stock intake, at your power level the manifold should not be the limiting factor. There are 4AGE's making 170 -180HP using the stock manifold. You can improve the manifold by removing the butterflies in the TVIS system, [ I'm assuming a race only car ] fish mouthing the ports as it transitions into the cylinder head, and you could also port the throttle body.
