The problem you found in this thread was inspired by many threads here on FABO. Many say "I have a *** limit budget, and I want to spiff up the stock 318. Many times it is said "find yourself a 340"....... So if this is realistic advice that people are giving, then it's a realistic question of which is actually the faster motor on that limited budget. Besides, many have claimed recently in 318 threads that they have good running 318's they pulled and are now taking up space and they would give them away free for the hauling..... So thus the "free good running 318 vs a core 340". For those that suggest the 340, is it really a better choice for 3k or less ???
