So I'm new on this forum and somewhat new to the slant six, I work on BBC's in race boats for a living so i'm a little dumb when it comes to the slant 6. I have a completely stock 225 in a 61 lancer and the car has been restored and got a new motor and nobody touched anything for about 10 years so i'm going throught the motor, it starts and runs but needs alot of work. First, is a pcv valve really neccessay on this motor? I had planned on just running a baffled breather and eliminating a lot of the stock crap on the motor.

I will be taking the 1bbl intake and carb off and putting on either a 4 bbl or 2 bbl holley/carter etc. Any preferences? Anybody see more power gains with one more than the other, I don't care about gas mileage.

Also bought petronix conversion, chrome valve cover and a bunch of other odds and ends.

any insight is much appreciated, thanks in advance.

Will it run without the PCV? Yes, absolutely; in fact most were produced with just a road draft tube. However, it will run better and stay cleaner with a properly functioning PCV. A vented cap will spew gunky oil all over the engine and engine bay. I'd stick with the PCV.

Growing older is unavoidable but growing up is strictly optional.

Unless the engine is a later model than the car it's not going to have much of anything you can remove. With stock long blocks the Super Six 2bbl is a good choice. If you go with more cam, compression and some head work you can use more carburetor flow of course. The Holley 350 cfm 2bbl is also a good choice for stock or mild builds. With a little work you can adapt the Holley to the Super Six manifold or an Offy or Clifford manifold.

Keep the PCV, and unless that chromed valve cover is a chromed stocker, I wouldn't recommend using it. Many of the aftermarket chrome covers lack the necessary baffles, and will cause the engine to lose oil. Unless that's a later motor swapped on, the PCV valve is pretty much the only smog equipment on it.
