1987 Buick GN Turbo V-6 - 10-Second TR

The LC2 is primed using a drill in the crank sensor hole.

Frank's original cam sensor is showing some gear wear, as well as wear in the housing supports above the gear. A cam sensor like this could start to get noisy, so a new cam sensor is used.

Time to set the cam sensor. Brian sticks a finger in the no. 1 spark plug hole until compression starts to come up, and then breaks out Casper's Electronics handy cam sensor setting tool. This takes the hard work out of setting timing at 25 degrees ATDC.At this point the alternator, motor mounts, knock sensor, and heater valve are installed; the last thing Cotton does before installing the motor is attach the flywheel with six bolts and Loctite.

Using an engine hoist, Brian raises the LC2 up and positions it over the engine bay.

Slowly, it is lowered until it's resting in the correct position.

Cotton's uses Dynotech Performance's 200-4R transmissions in its builds. This version, a Hi-Pro, can be fortified with a slew of billet components to withstand 9-second passes. Since Frank won't be pushing his GN that hard, the standard Hi-Pro without the billet options will be fine for this 10-second Buick. A 10.5-inch, 3300-stall lockup Pro Torque converter will match up with the 70 turbo nicely. With the converter mated up, Brian lifts the Dynotech tranny into position and installs the six bellhousing bolts.
