Zach B: Cheap hot rod trick. How to get 50 more horse power from a 216? Replace it with a 235. 90 HP from a stock 216 later version, 140 from a 234 with hydraulic lifters. About $200 for one if you can find it. Can't do that with a small block. Not for $200 anyway. That is why the change is so popular. The 235 is safe to run at higher RPM over longer time so what is not to like? Use the Truck front mount and it bolts right in. Deal with the fan to radiator clearance and you are done. Same flywheel same clutch and same bell housing. Same starter and same generator. Same points and regulator if you keep it 6 volts so no charges there. Same manifold if you like. 235 is worth rebuild if needed or find another one lots out there. To make a 216 into a full pressure motor you have to drill the crankshaft to deliver oil to the rods. You need to machine the rods to accept an insert bearing and...still get 90 HP. Bet that cost more than the 235. If you want a stock preservation or restoration truck then by all means rebuild the 216. Your choice for sure.
