I know for my application I need to get away from the original 216. I have a full pressure 235 that I could use. I understand that this motor is not a full flow motor. What difference will this make for a daily driver in reliability and longevity? Should I consider going with a 270, 304, etc., for my application for any other reasons than added power and torque?
The 235 will make a good engine for you. I think there's a tech tip on converting it to a full flow filter. The 235 & 216 were built without oil filters, but have fittings to equip them with a bypass filter, which filters about 10% of the oil that is pumped, and drains it back into the crankcase. With a full flow filter, all of the oil pumped passes through the filter. Don't know how much difference it actually makes in engine life, but it can't hurt. Conversion is easy if you already have the engine apart.
As for the GMC 270 & 302, they are better engines, and with a higher nickel block they will last longer. GMC made a better engine, no doubt about it. They are harder to put in, the block is longer. You might want to consider the 261, Chevy's truck engine.
As for the five bolt wheel, you can bolt the hubcap clips on a later model GM wheel.
Sounds like you're on the right track by doing your homework first.
