If you are going to keep the PG(automatic) then forget the 140HP engine and go with a latter 110HP engine. Mind you - there is nothing like looking at a 140HP engine - those four carbs, but the 110HP engine and the PG are such a great combination and easier to live with. When GM hooked up the 140HP engine to the PG the low RPM response was not as good as the 110HP. So GM installed a milder cam and used a special (140HP PG only) crank gear to increase the low RPM torque, yet provide some higher RPM power vs the 110HP. Of course this required making some PG changes to increase RPM upshift values. Bottom line IMHO - a 140HP PG setup offers very little improvement over the 110HP PG setup and a lot more complexity (carb linkage, dual mufflers, etc.), not to mention 140 HP heads require a deep seat rebuild to be reliable.

It's your car, do what you want, but one can end up with a lot of time and money involved, become frustrated and loose interest. Keep it simple, get it on the road, enjoy. Then later you can decide to do upgrades.

Agreed.

I'm sure I'll end up running the stock engine as long as it is reasonably reliable.

The 140 based engine swap would have a substantial increase in displacement. But maybe port FI is a better answer when doing a swap.

The 140HP engine has the same displacement as the 110HP engine. Actually ALL 64 model year engines had the larger displacement, but in 65 they widened the cylinder top flange and the corresponding head opening to allow for more gasket sealing area.

Apologies for my bad writing. I meant a 140 might be a good candidate for an 3.1l/3.3l upgrade and then for an engine swap.

Very similar engine operation and characteristics just a nice shot of low and mid range torque.

Leave the FI out for now. Even the stock 2.7l with the twin carbs might be a reasonable candidate for the displacement upgrade. A 3.08 diff might be a good addition with more torque.

The 3.08 ring and pinion are RARE. Also too steep for a PG car - IMHO. You'll just end up wasting energy in the torque converter. Most PG cars came with 3.55 and 3.27 (highway) gears. The 3.55 gives more go off the line, but with the 3.27 the engine is a little quieter (lower RPM) on the highway.

If you redo the seats, makes sure you put in new foam. Clark's sells the bucket seat foam. The back seat foam/pad can be recreated by any good upholstery shop. The rear is just a foam sheet cut to fit with a cotton batting layer. Available from a good upholster supply shop.
