Thanks all for the great ideas and real-world examples.
Jasperstang308 did you change out your combo in its entire, or did you ever bolt up larger heads (And notice a difference)

Joel5.0 sadly my original 289 block had a hard life, the original owner claimed to have put 400,000 on it, just before he sold it to me a bud "rebuilt" the engine by way of replacing bearings and rings ONLY, the pistons rocked so much in the bore that they are severly scratched, the bores are scored, the engine had loud piston slap, I drove it for perhaps 80 miles (he had put on about 200) before I had to park the car (I installed a 1970 complete engine later) My bad, I didnt store the engine properly and now (14 years later) there is rust in a few bores but the pistons came out OK but It wont be cheap to re-use that block (and the pistons are junk)

SO no not using that engine. For reasons of economy and to experiment I am using a 5.0 from a 1989 H.O Mustang. I am re-using the block and forged pistons. The bore looks wonderful but am taking it today to taylorengine.com today along with the 289 crank and rods from my 67 mustang's engine. I also have a new cast flywheel

no had an accident and sold everything. look up my vid on you tube or it may be still in my profile still. you can hear how radical it was. i bet with larger heads it definitely wouldnt have sounded the same
