Re: 80cc engine?
Now that I got to my computer let me explain, in nascar engines the bore has gone up over the years and the stroke shortened. This has proven to increase the low end torque greatly. A 350 ci chevy small block has a bore of 4 inches, the current nationwide 358ci toyota engine has a bore of 4.470 inches. nationwide engines have about 200 less hp than sprint cup engines which specs. are hard to find.
Your results may not be the same,Greg
