Check the compression and leakdown. If it is under 150 you will run at the back. Might also check timing, often it is too far advanced. Much over 32* might slow it down, IMHO.
check the cam timing quick by finding a true TDC mark and making sure that both lifters are evenly depressed at TDC. You can get pretty close with a caliper as a depth guage, pretty close by eye , after a few times. The TDC mark is in the book, and often not the timing mark, dont get them mixed up. Most of the time it is 10-11mm before the clutch cover bolt. Use a degree wheel to get it right, if you are going to move it.
FWIW I have never had a gear set checked, or compression checked, or cam checked. Most of the ITB cars have the same gear sets from the sound of things and we all shift pretty much at the same spot.Except the 4.22 cars, they are one gear higher and get draft passed some times. But they are fast also. 4.66 is a lot of gear, that works out to be about 105 mph race car .
They all said that I had too much cam on Sat pm. but none put up 100$ to take my bet. my mixture was too rich for the afternoon heat and idled rough. The cam was(still is) untouched VW, set ahead a couple .
I know at ARRC that stuff gets taken apart. Hey, a Mustang ran near or on my times(2:44 sebring) last time out at 2650# ?? I dont think so legally, Maybe tho. It was colder and good for one second probably.
