I just recently bought my first vintage '78 TX440 free air couple of weeks ago. Just the other day, I had her out for the first time for a short ride - I was impressed how fast that little 440 can do. I do remembered hearing that '78 440 engines were bumped up to few more ponies over the older '76 - '77 TX 440 engines. Anyone can tell me approx what hp this thing puts out, what type of spark plugs should it use and one last question, with stock pipes, what should the motor peak revs at? Any informations, would greatly be appreciated. Thanks. WL.

TX440 uses engine EC44PT-05
clutch uses standard weight A with an orange spring
recommended plugs;
AC S41XL
Champion N2
NGK BR9ES
Gapped at 0.020
oil mix 40:1 and run regular gas.
the 400 F/A was 60 hp. the 440 should be between 62-65 hp.
