I own a 1990 MAF California 2.9 that I endurance track race. Truck is run HARD for 8 hours at a time. It's a budget program, so we look for ways to make small improvements cheaply. The engine has headers, straight pipes and an airbox delete. Unnecessary accessories have been deleted and electric fan installed. I've read enough of these forums to be dangerous but don't want to take anything in the wrong direction. Appreciate any input you have.
One of the things recommended to me is to replace the valve cover cap and tube (I believe this is called the crank case breather) with a breather and plug the inlet on the intake manifold. Any issues with this?
The 86/87 Throttle body replacement seems like a no brainer. However, it seems like the MAF diameter is very small and may limit the TB increase?
One thing I found on my current TB is full throttle wasn't opening the butterfly valve completely. I corrected this by dremeling the stop. (I haven't seen this mentioned much around here, so thought I'd point it out for others to check).
We redid plugs a few months ago, planning on reverse flushing the injectors this weekend. If there are any other low hanging fruit, I'm all ears. Thanks for taking the time to read this.
