I am fairly new to the Chevy 6 cylinder, but have been in dragracing and street cars for a lot of years. Dad has been racing since 1955 and wrote a book about Pontiacs. Check the web for
" How to Build Max Performance Pontiac V8s" by Jim Hand. We have our own flowbench and each of has made 100s trips down the drag strip. One night dad made over 20 passes just checking mufflers, and another night made 25 passes checking intake manifolds. His car can repeat with in a few thousands of a second due to traction a wagon has. Its weighs in at 4030lbs with him in it, runs 92 octane pump gas, 462 cu inch with iron heads, leaves the line at 1800 and shifts at 5400, dot tires, full exhaust with x pipe, and he drives to and from the track. It has run as fast a 11.32 @ 117 mph, and now is running 11.60 @ 116 with a factory intake, Q-jet carb, and a factory camshaft from a 65-70 Ram Air GTO.

My car was a 67 Pontiac, alcohol burning 455, full exhaust running 11.0 @ 122 mph with factory short block, iron heads, and shifting at 5300rpm.

I may not know the inline, but I do know engines what makes them work! Joe
