This is what you don't want to see ... but if you have to find a damaged roller lifter it is better when it hasn't blown apart yet! The new Red Zone Roller Lifters from Isky Cams will just about eliminate this problem. The wheel is pitted and is loose on the pin as the small roller bearings have failed.

Richard at Isky Cams recommended a #RR-714/78-84. A .714” lift cam that idles smoothly at 1200 in our car and responds instantly to the throttle. It was a great choice for our Chevy and the parts from Isky Cams combined to make an easy to install and reliable valve-train package.

We looked into the fuel system and noticed the fuel pressure was falling off after the 1/8 mile. We used a Mallory fuel pressure gauge isolator that allowed us to put a gauge in the cockpit of the dragster but not the actual fuel line. The isolator uses a diaphragm that separates the actual fuel line, which is full of alcohol, and pressurizes the line that has anti-freeze in it that runs to the front pressure gauge. We started with 8 pounds but by the 1/8 mile it was just 4 pounds, way below the 8 to 10 pounds we want for alcohol. The culprit was a well-worn and leaking electric fuel pump. From previous success with the Barry Grant belt drive pump I decided to call Barry Grant and see what they had.

Barry Grant belt drive fuel pump with our slightly modified mounting bracket and the three-way shut off valve can be seen in photod.

We decided on the BG Belt Drive pump #176001 and the Lower Right Hand Mounting Kit from Barry Grant. We added a three-way shut-off valve (required for all belt drive pumps) and the Barry Grant adjustable By-Pass Regulator. I wanted the old trusty 1095 King Demon alcohol carb back to put on my Mopar so we opted for the new version from Demon. It is part #9728025DR. They have made some changes to the carburetor since I got my first one three years ago and I was anxious to see how it performed.
We had to change the fuel line sizes and I wanted to run a BG Fuel Filter to protect the pump and carb from “junk”. It took some looking in the parts catalogs to get the right fittings but I got everything adapted from the #12AN fitting out of the fuel cell to a #10 on the fuel filter and from the #10AN outlet on the fuel filter to the #10 inlet on the fuel pump. After that it is all #8 fuel line from the pump to the carburetor and then the return line to the fuel cell.

This is how we did the fittings to reduce the #12 fuel cell outlet to the #10 filter fittings. We didn't have room for hose ends so the Russell fittings made this possible.
