Ironmike mentioned it being winter and his brain working overtime on gearhead stuph.... same thing here LOL
Dartfreak75's long decision making process led to this little project, and we've PM'd back and forth on solutions. He provided some of his 318 piston-rod assemblies for weighing to get a grip on bobweights, so he gets a big thumbs-up for helping.
Some bobweights first:

- Problem: The 318 LA's low compression pistons
- Solution: Put in higher compression pistons like KB's; that opens up the cam selections for a torquey street engine
- Next problem: The lighter pistons require a re-balance, and that damages the budget by $250-300.... that's almost as much as the KB167 pistons.
- For the guys on a budget, that re-balance is just another barrier to improving the engine.
Some bobweights first:
- Stock 318 with the later heavy rod: 2169 grams with nominal component weights
- Actual measured 318 parts with slightly heavier than standard rods: 2177 grams.
- Put in KB167's as shipped and bobweight drops to 2093 grams... which is why a re-balance is normally needed
