Re: Tech Teardowns in Stock Eliminator
Allen Sherman went through a big teardown on his Corvette at the 2015 Indy event.
He has to pull the engine, pull a piston rod assembly, they checked throttle body, intake, heads camshaft, crankshaft stroke. They also checked the wheelbase, front and rear overhand of the body. In addition to his car, he had to assist Stock and Super Stock customers that were torn down too. |

A typical rod and piston tear down.

Re: Tech Teardowns in Stock Eliminator
Who determines who and what gets tore down? Is there a procedure, I can see winning or record setting, or just bring all your tools for supprize inspection?

Re: Tech Teardowns in Stock Eliminator
J Allen will also tell you NHRA had NO engine stands. Laid engine on side on a pallet to pull piston. Stupid Nhra bulls...t

Re: Tech Teardowns in Stock Eliminator
1978, Gainesville..The top 16 had to go to the local Pontiac dealer and pull pistons.I happened to be 15th, with the R/Stock 283 car.
Easiest way was to pull the whole engine, set it back on the flywheel, and pull the pan that way. Of course, no engine stands. Anyway...rolled it in at 5 pm...Started it and drove it out at 10. We don't work that hard or fast anymore.

Re: Tech Teardowns in Stock Eliminator
I was there in 78 crewing for WA Lee. I don't remember pulling a piston and rod. Just a head as I recall.

Re: Tech Teardowns in Stock Eliminator
We got torn down one year at Pomona with one of the Chevelles. It wasn't too scary.The first thing that wanted to see was the carb. I pulled it and sent it and the card with the driver to the carb tech guy,meanwhile,I pulled the intake, and the tech guy at large asked me to pull the left head. Carb came up good, so I sent the driver with the intake to that tech guy. I got the head off, removed the rocker arms, and took the head to the head guy. First, use carb spray, brake cleaner,do whatever, get the head SPOTLESS. The head went onto a fixture, we used a test spark plug, and we CC'd one combustion chamber at random. It came up good, he then gave me a valve spring compressor and told me to remove one intake and one exhaust valve at random from two different cylinders. The valve went into a fixture to determine the valve seat angle was in spec, both valves were OK,then the head got a visual by a couple of tech inspectors.It came up OK, so the head went back together. He met me back at the car, then asked me to pull two lifters.He measured the overall installed height of the lifter,came up with a real nice brass test lifter that was adjustable,we reassembled the valve train, and he checked max lift on those two lobes with a real nice dial indicator test stand that bolted to the head, they both passed by a few, then he checked the bore with a dial bore gauge,then used a magnetic deck bridge and a long dial indicator to verify the engine's stroke. Be sure you have a long breaker bar for ease of rotating the crank. The longer the bar, the more accurately you can do this.I also had to clean the top of a piston so the manufacturers' part number or brand name was visible in order to verify legality of the engine's piston. We came up good, I set the head up with a new gasket and bolted up the header, then they towed the car back to our pit space with an official NHRA golf cart where I torqued the head,installed the intake, adjusted the valves, dropped in the distributor and the carb, and lit it off and timed it. Total time for all this was about five hours, but we were the first team apart and out of there. Glad to be done with it.
