Arrow Dad played at the strip with a 1970 GTO 400/4spd in the late 1970s

All of the racing was at the old Bonneville Raceway in SLC Utah @ 4200ish feet.

GTO had the original 'WT' motor and '12' heads with around 95k miles, Muncie wide-ratio 4-spd 3.23 open 10-bolt rearend and LR50x15 Radial TAs on the back.

He started with it pretty much stock, possibly bumped the timing to 16 degrees BTDC, flipped the air cleaner top and ran 'CC' secondary rods in the qjet. 14.60@95-96mph.

Swapped in a Crane blueprinted '044' camshaft with factory 1.65 rockers, installed a set of 4-tube Doug Thorley headers hooked to the stock exhaust and installed a Moroso chrome 14x3" air cleaner. Dropped down to 14.45@98mph.

He says that the 044 was his favorite camshaft to that point because the idle sounded so good. Especially uncorked....

Added a Holley blue fuel pump, Moroso cool can filled with ice and uncorked the headers and it went 14.20@101mph.

Put on a factory #483674 1971 455HO aluminum intake using home-made block-off plates. Put ice under the intake in the staging lanes. 14.0@102mph.

And, finally, at the insistence of his younger brother, pulled off the P/S belt. Ran a best-ever of 13.78@104.5mph, shifting at 5500 rpms.

Then it lost a couple rod bearings..........thank you Fram oil filter company.........
