aprox what hp does the more aggressive 686 have
also is it reliable as the mild 686
do you have to replace the connecting rod & install fcr carbs????

 

call Trinity for exact details:

but the basic difference is a higher compression piston, 5 new valves and springs, different porting, hotter cam....requires race gas...you don't have to get the carbs. The carbs create more power with this setup as compared to the mild setup though.

 

I would suggest going with the Carillo rod. For the $200 - $250 it's worth the piece of mind that your stock rod won't fail. Trust me (I learned the hard and expensive way), if the rod fails, it will cost you a whole lot more then $250.
