To answer a few of CSX4027 questions which might be of interest to everyone. we were in business with Kuntz 12 years ago and I imagine his portin g as well as our porting has come a long way in that time.
We purchased 340,000.00 worth of CNC and digitizing equipement to do all of our work in house so it could not be copied or used by someone else. This consisted of a DMG 80 5-axis simultanious CNC machining center as well as digitizing equipement with the latest software. This equipement is second to none and better than most Cup teams have. I have made several changes to our heads as we learn more things that help them. This use to require shipping the head else where and waiting making a small change take up to a month. With the software we have we can grow the port bigger or make it smaller, raise the roof or floor of the port. This has really taken us to the next level on heads. I figure we have machined about 30 sets of FE heads on it so far. We of course are doing a lot of small block heads as well as heads for other shops and Brodix.
We have developed a Stage 2 and Stage 3 head with the Edelbrock casting and a CNC package for the Shelby head as well. This has been one of the best investments that we have m ade in equipement. Every head is cut the same as the last one with every port the same. We can also digitize a port for any body with a good working head and they want to use that port a lot. There is more to the heads than just the porting like valve job, valve back cuts, springs used and pressures. Of course we still have to develope the port by hand and test it but once that is done we can duplicate it. I hope this helps explain our cylinder head program. We are adding programs daily and still need to develope some more. If we can help in any way let us know. Thanks Keith
