I installed the C8AX-C in my '70 Shelby GT-500 for a short time, but it was difficult to stop due to low manifold vacuum at idle and low speeds.  Definitely a step up from stock, but not a daily driver type.  Joe-JDC

This is with the stock 2.189/2.190" intake valve and 1.6245" exhaust valves.  Still the MR gasket size, not enlarged for CJ, or  other intake manifolds.  I don't think posting higher lift numbers does anyone any benefit since most of the street/strip engines that folks around here seldom have camshafts with lift numbers above .700-.725" lifts.  Once the valve gets beyond the combustion chamber edge, the flow will go up some all the way to 1.000" or more and that is not something I will ever post.  Yes, Jay's tunnel port heads can flow 425cfm and more with careful attention to taper of port, and his big heads have been tweaked to 459-460cfm.  There is absolutely no reason to argue over flow numbers unless you flow the different heads on the same flow bench with the same operator on the same day under the same conditions.  If someone wants a certified flow sheet I will do a calibration check before starting a flow test just to make sure the machine is set up correctly and the room temperature is always the same.  I have my shop air conditioner set to 71* and have always verified no leakage before starting a test using at least a 7/16" radius for the intake port opening.  On many heads I have acrylic venturi already formed with a radius that is exact for every head and not subject to clay manipulation.  I use head bolts to position the FE head with threads into the flow bench fixture so that the head is always in the same position for every test.   Taking the variables out is paramount to valid and consistent results.  JMO, your experience may differ.  Joe-JDC   

The adapter is a 13012 that has not been opened up to fit anything as yet.  Yes, it is for sale.  Joe-JDC

I would like to let folks know that I am still getting requests for hand porting work from several sources asking for special combinations and information on who is out there that will actually port an iron head, or new aluminum heads and manifolds.  I wonder if it would be possible for a line item that would list specific shops or individuals that are still operating machine shops or porting shops that would answer the need for FE hand/CNC porting?  I know there are several folks here that perform gasket matching, hand porting, and sell performance parts, but no one specifically says that they actually accept porting jobs.  I could still stay busy 6 days a week with the requests, but I am 80 years old and have developed arthritis in my left hand that is getting to the point it is difficult to lift iron heads and turn them over as necessary for porting and do a professional job.   Jay is this a possibility for a section for services strictly for FE porting or machine work?  Do you the FE guys think it is needed?   I hate to keep turning folks down, especially those who have been customers in the past without a recommendation for someone who does quality work at a reasonable price.  Location, state, services available, and contact information would be a bonus or is this a can of worms?  Joe-JDC   

I put Stabil in one of my Mustang GTs gas tank because I knew it would be sitting for a couple of months.  When I went to start the car to move it, it would not start.  I opened the gas fill cap and the gas tube was rusted all the way to the tank.  The fuel was a gel, and the fuel pump had to be replaced.  Never again!  No Stabil for me.  Joe-JDC
