If you are gonna rebuild the 2332, run the CB panchitos heads, and get the CNC chamber option at 63cc, so you can run 9.0 and .045″ deck height. Order the matching cast manifolds at the same time
The panchitos castings are amazing and built to cool better. No flashing, extra fins and way heavier. They also have killer airspeed, and that is what makes torque. More money for sure, but worth it. Power is in the heads, and in this case, also better cooling.
I am a huge fan of the Web 218 for buses, and it would I be perfect for what you are wanting to do. Some Engle cams are OK, but most were designed in the early ’70’s and adapted from other engines. The Web stuff is way more modern, and makes more power without extra noise or wear
The 1 5/8 heater boxes will work aweosme and perfect for what you are after.
Make sure your guy dials in the deck height to .045″ and doesn’t just slap it together where ever it lands. Details are important!!
Gearing is super important. The engine needs to be about 3200rpm at cruising speed for max cooling. Having the peak torque just above your cruising speed also keeps the engine cruising where it’s most efficient, and cools best. The Web 218 in my 2332 quits revving at about 5300rpm, and peak torque is about 4000rpm.
It’s all about the entire package from the carbs down to the tires. Every component in between needs to be matched, and it all needs to be planned out to work together.
Where is your cooler mounted now?
Just a few suggestions to think about. I don’t know much, but I do have some successful big bus engines under my belt, with quite a few hard miles on them. I learn something new from every one, and I always try to continue to improve them each time.
