Greetings all,
Well, I removed the 327 engine from the boat after talking to the original owner and he informed me that the engine was experiencing blow back so the engine was due for work. After sitting 33 years I was amazed that it was not stuck. Being .060 over I thought I might just need to replace the short block with a 350 small block.
This is where I could use some help. I've been researching marine engines verses car engines, Dart short blocks and have some mechanics that want to open up the 327 and install oversize rings, check the bearings and rebuild the Corvette heads.
US Marine offers a 1995 Chevy 350 long block with a 7 year guarantee for $2,600. A Dart 350 is around the same in short block. Rebuilding the 327 with oversize rings, new bearings and head work is around $1,500.
Since these boats are delivering speed at higher rpms than cars going similar speeds, I thought that the marine application may be a better choice with the specific cams, valve springs and balancing that work better at sustained high rpms.
What do you think? Want to build the boat with the most reliable potential. Once I get it back in, I really don't want to take it out for a long time.
