Does anyone have belt length recorded for 67 427ci 390 horse with power steering? I need all three belt sizes.

My 1970 Corvette Parts Book shows the dimensions for the 67 427 belts as follows:;

Alternator - 3/8" x 31 5/8" GM Part Number 3878243

Water Pump - 3/8" x 34 3/8" GM Part Number 3837810

Power Steering Pump - 3/8" x 45" GM Part Number 3878244

Have any of the pulleys changed over the last 50 years?

rccarson

thank you for the response.
No, the pulleys are all stock to the car. The belts are all specific to 1967 so the 1970 belts will not work. And the auto parts listing do not fit.

thicut it s is easy.....just take the longest belt, cut the belt and wrap the belt into the necessary pulleys you want touse, mark it and measure the overall
length......belts have the length numbers printed in its sleeve

any parts store should help

Go back and reread my response.

They are NOT the dimensions for 1970, they are the dimensions FOR the 67 427, taken FROM a 1970 Corvette Parts Book.

Tho only reason I mentioned the 70 parts book, was so that you would have a point of reference as to where the information came from.

Below are the pages from the parts book, showing the 67 belts, their applications, their part numbers and the chart to cross reference the part numbers with dimensions. GM calls alternators "Generators", air conditioning is "C.A.C.", power steering is "P/S", "w/" is with, and "exc." means except with.

Thank you GB Vette! Picked up the belts this morning and everything fit.
In the future I will pay more attention to the response.
