Does anyone have a part number for the external drive belt for a 97 Lt1 4.5 PSI Powerdyne kit. The current belt is around 41 inches, I'm in Germany so its not easy to refrence parts. Dayco or Goodyear part #
Thans in advance

 

IROCARMY:
A 40" belt works. GYR4060400. If you have the ~75mm OD tension pulley you may be able to use the 39" GYR 4060390. The books show a 39.5 0395 belt should be available but I've never found one. The 40" will just work if your tension pulley is 85mm OD.
Good Luck

 

BTW ... the above are Goodyear numbers and this is with a 6" crank pulley and a 3" or 2.75" SC pulley.

Thanks for the help, my current belt was in rough shape. I will order the belt while the SC is being rebuilt at 928 motorsports

Just to close this out, GYR4060400 worked out great. Unknown to me the previous owener was running a 5 groove belt, now I have the correct 6 groove one. Also I can say that 928 Motorsport did a great job rebuilding the Powerdyne.
