Hello everyone,
I have a 1972 400 HP motor with a cast crank and 346 heads (double springs). I thought about doing a stroker (451 - with a 440 crank, or a 440 source kit, but I do not think I need to rebuild the engine).
I would like decent power - maybe 350 HP and 400 TQ. More the better, but not necessary. A nice driver engine.
It seems so far to be a low-mileage engine.
The engine turned over by hand with no issues.
I took off a cylinder head to inspect the cylinder walls and they look very good.
Still has a Chrysler gasket (gold/pink color).
Now, I am deciding what to do.
I would like to refresh the engine instead of a full rebuild to save money.
I believe the engine is standard bore.
I would like to hone the cylinders, polish the crank, replace the cam (maybe a Hughes Whiplash cam), and re-gasket the engine.
Do I have to replace the pistons? Can I get away with a re-ring? --> Do I have to rebalance the engine if I replace the pistons?
Any reservations about doing a refresh instead of a rebuild?
Another not-so-related question, I pulled off a cylinder head. I tried to do it the right way by unbolting evenly throughout the rocker assembly and heads.
Can I bolt the head and rocker assembly back on the engine now that I have taken them off? I have everything organized.
Thank you.
