Need firing order and location of #1 cylinder. 1968 Buick GS400 Not a nailhead engine.


All Buick V-8's use the same firing order in 1968 and it is 1-8-4-3-6-5-7-2. The odd pistons are on driver's side front to back and even on the passenger. The distributor turns clockwise and #1 is at 8 o'clock on the cap. Plugs are 44TS and gapped at .030. Points are gapped at .016 and the dwell angle is 30. Timing should be TDC. If you have A/C set your curb idle with the A/C switch in the "Full On' position and the car in Drive. Idle is 600RPM for automatic and 700 RPM for standard. Hope this helps.

Own 1983 buick regal, 3.8 L v6- want to install a 350 smallblock.Is this feasible? The 3.8 is a lemon, and it's very difficult to get parts for the motor.


Depends on which 3.8 you have because there were two avaliable in that car .One was the buick 231 cubic in and the distributor was on the fron of the engine.The other was the chevy 229 cubic inch engine and the distibutor was in the back just like on the small block v8.If you have the buick motor be prepared to swap everything including wiring harness and transmission.If you have the chevy v6 it not so bad but you will really need a donor car(monte carlo,cutlas,lemans)with a 305 or 350 for the wiring harness ,radiator shroud ( shorter on the v8) ,a/c lines (longer on the v8).Years ago I had a lemans wagon with the chevy 3.8 that i put a Monte Carlo ss motor in and it looked like it came with it.bought a wrecked mc( hit in the rear) and swapped everything.Including coil springs and sway bars front and rear.And yes the SS 15 inch wheels too! It was a real cool sleeper.Miss that car.
