Re: 302 Chevrolet Engine Build
I have been working on the head porting, a lot of time spent on this.

Re: 302 Chevrolet Engine Build
Those B'ski fixtures are very time saving. You may want to try modeling clay to help raidus the inlet adapter, it will help reduce noise.

Re: 302 Chevrolet Engine Build
Looking good... Mike...
I grew up in service station/garage.. which transititioned to machine shop... When I was 12-13 years old people were a little freaked out, when I had their heads off or swapping cams or working on their brakes...…learned a lot, especially about people Doing what you are.... you have evidently spent a lot of time watching and learning.. Is that what your Dad does for a living? |

Re: 302 Chevrolet Engine Build
I thank everyone for their support and help. My inlet radius was given to me be the Disident and it fits the port perfect, it is joined to the port by green modeling clay, nasty stuff thats hard to get off. anything it touches. I have 254 CFM @ .650 lift with a 4.030 bore @ 28 inches, I want a solid 260. I do work in the shop with my Dad.

Re: 302 Chevrolet Engine Build
For those who have made comments about the radius entry piece that Mike is using while flow testing his project 302 heads....It is NOT a Brezyinsky piece. It is home grown and cast right here in Colorado. It employs a very liberal radius and is adequately thick to encourage no "edge effects" from lesser radii designs.
Mikey, keep doing what you are doing and enjoying it too! BTW - If one sees the manometers bouncing around, it is typically a sign of bi-stable airflow that needs to be addressed in the port, not from just changing the radius inlet guide.

Re: 302 Chevrolet Engine Build
I hope I can explain myself correctly. I believe you use a wand to go into a port and measure air speed or flow I guess. If the air speed drops alot on a inside radius of port, would you want to fill the radius to get speed up or get a larger radius to help speed up air? If it sounds like I don't know what Im talking about just say so as I have not been around flow benches all but a couple times
