| | | | Joined: Nov 2005 Posts: 41 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 41 | I just purchased a 1969 Chevrolet C10 step side and was told the engine was a 235. When I got the truck the Distributor is toward the front of the engine not in the middle. I suspect this is a 230 engine. I have the casting number as 3921968 and the number just behind the Distributor is F0602PP. Can anyone help me confirm the engine type> The VIN number is CS149 J 864449 if that helps. Thanks Pete

If you can get a borescope into one of the spark plug holes, look at the top of the piston. The 230 has a flat top piston, and the 250 has about a 1/4" deep dish in the piston crown. You might even be able to check the piston with a long, narrow screwdriver blade with the piston near the top of its stroke.

C = Conventional Cab S = 6-cylinder engine 1 = GVW range (3900-5800) 4 = Model (Pickup) 9 = Year (1969) J = Janesville Assembly Plant 864449 = unit number starting with 100001, so you have the 764,449th unit built for the 1969 model year from the Janesville Plant. The smallest 6-cylinder available in a C-10 in 1969 was the 250.

My fuel pump is closer to the distributor but my distributor looks more like the 292 picture. Are they interchangeable?? I couldn't get my bore scope to work today but will keep trying.

The 292 is the only engine with them offset side to side. The 194, 230, and 250 have mounts directly across from each other, and the same distance from the bellhousing as a V8. The passenger's side mount on a 292 is about 3 inches further forward than the driver's side mount. The HEI distributor with the large diaqmeter housing and cap will fit the earliuer engines with point-type distributors.
