Re: 400hp 68 tri power motor pulleys and valve cov
vlado-----
The waterpump pulley for your application was either of the below:
early (and without M-40 or C-60)----- a 2 groove rear pulley of GM #3848904 "sandwiched" with a 1 groove front pulley of GM #3883235;
late (or any with M-40 and/or C-60)---- a 3 groove pulley of GM #3889372.
None of the above pullies are available from GM but they are available in reproduction.
Crankshaft pulley----a 2 groove, stamped steel pulley of GM #3921923.
The above pulley remains available from GM
I can't advise as to other engine pullies since you have not provided enough information regarding how the car is equipped.
As far as valve covers are concerned, just about any big block valve cover will work for you. As far as what's "correct", that's another matter. There are too many subtle differences in big block valve covers too describe exactly what you need. Most of the differences apply to the the presence of, configuration of, or exact placement of spark plug wire brackets and/or other wiring "clips".
GENERALLY, what you need are flash chromed valve covers with drippers. These valve covers will have wire stands towards the rear of each side and will have small brackets for 2 wire looms spot welded on about midway for the left side cover and more rearward for the right side.
1968 used 2 different configurations for the rear of the left side (driver side) valve cover. Early used the "flattened corner" design like 65-67. Later, used the "60 degree tapered" design like all 69-74.In Appreciation of John Hinckley -
