I have found out that a rebuild on my 73 400 would be in order and make sense at this point since the engine is out. We removed it to replace the oil pan and a rear main seal for assurance with the 2 piece bop seal.
After removing the oil pan with my engine builder, it became apparent that the bearing had wear and the cylinder walls were showing some possible blow by. So he said it would be a good idea to do the rebuild now as oppose to replacing the bearings, oil/rear main seals and pulling the engine again in a couple of years to do the rebuild. Looks like the bearings were last change in the early 80's. Currently has flat top forged pistons.
My question is, where do I go from here? Do I do a standard rebuild which he said could bring me to around 375 hp / 460 torque or so ( according to the builder ) . The engine will be broken in and dyno before it goes back in. Or do I go for a stroker kit? If I do put in a stroker kit, what other components need to be upgraded to handle the extra torque? Rear end is 3.08 posi. It is a 80 TA with T-Tops that originally had the 301. Are there any disadvantages with a stroker kit in this 1973 400 block?
The present comp cam with the 230/236 duration at 50, new lifters, new chain have about 1300 miles. They were changed by previous owner. So I think these part could be reused?
