I'm here to help
there is a lot of misinformation on forums people just say things but if you got data to back up statements it becomes factual information.
I had to sell that ported throttle body that is seen above pictures to buy my new motor and right now I am currently working on a new design that I hope to flow test vs this one and compare the two.
here is a teaser:
If I can get a hold of an air compressor for cheap I will start providing porting services for people, and I've ported cylinder heads and other oddities and I have an educational background in engine airflow so you know your getting it done right.
