Big Pine Key looks destroyed, did you weather Irma OK?

For those looking to upgrade to a C5/6 IRS google Dobbertin Performance. Nice way to adapt the C5/6 IRS cradle and links. Grampy

extend the push rod bore Just a thought. In looking at the photos of the disassembled C5 MC there seems to be enough meat in the primary piston to have a bore deep enough to ensure the push rod will not fall out. Clearance between the push rod and the primary piston only needs to be about 1/8...

should work in a C2 as well I am also interested in getting rid of 10 lb of cast iron master cylinder. Doing a search it looks like TT had a lot of specific knowledge on the swap and the push rod problems associated with the C5 MS in a manual brake application, maybe he can jump in and add a...

Hi Garys 68. Yes I have seen the article. Ken, the owner and builder was kind enough to give me some advice and encouragement when I started out. He did a terrific job with his project. Grampy

Hey Kid, I've run the mechanical injector on and off for about 30 years. I have wanted to convert to sequential electronic for a long time. I've done most of the work but I travel a lot and I'm slow. I still have more work to finish the cold air supply. The ECU is the current Holley...

After way too much time my project converting a Rochester 7375 to EFI is almost finshed so I thought I'd post a few pictures. Grampy

Thanks TT, I'll contact Kinsler. My surge tank vent line is -6 which is the same size as feed from the low pressure pump. The fluid velocities in the system are in the normal range so not much back pressure can be expected. I could insert a fixed orifice to make back pressure but the sizing...

Backpressure valve Hey TT what 5 psi backpressure valve do you use? I'd like to build a little back pressure in my surge tank. The tank is not readily accessable (PIA to get to)so I'd like to use a proven piece. Do you have a maker and part#? Thanks, Grampy

it takes me a long time to do anything I finished the surge tank. Original gas tank was modified with two 9/16th holes for return line fittings. The surge tank mounts on the frame behind the right rear tire. The external low pressure pump is fed from the tank and fills the surge tank. The...

Gene, Two pumps are to prevent running out fuel as you did with a usable amount of fuel in the main tank. If you gravity feed the small tank and lose the syphon in the main tank pick-up the frame rail pump may not be able to pull through the surge tank. 2 pumps are absolutely more costly and...
