Need a liitle help again and thanks putting rebuilt 350 into 69 c10 that started with 250. First problem the pulleys on the water pump don't lim\ne up wit the pulleys on the vibration dampener new water pump same as old one on the 350 any advice? how do I know if the dampener is on all the way?
Tightened to 85 ftlb. next will the linkage for the throttle forthe 250 which is just a striaght rod work on the 350. It has a performer intake with an edelbrock 1406 600 carb only things i see is that the rood is too short trying to figure this out thanks dave

Are you mixing short/long water pumps?? There are both available for chevys. The short one will just about touch the timing chain cover. Long ones have a 1/2"-3/4" or so gap. Chevy put out about a million or so pulleys. You need to get a setup off one that lines up and compare. I have a few small blocks with pullys on around here and can measure something if you want.

Was pulleys aready on engine? ( six pulleys will not work on V-8) Did you get the same pump ?(short or long) Find a V-8 rod or cut the one you have into and weld in a piece or buy a piece of all-thread.

ok jhow66 thanks for th help yea I thought that would work for the throttle linkage. I have the short pump just seems to need about a 1/4 of inch if I lay the pump pulley, there are two that are together, flat the height measures 3 " and I need 2 3/4" one thing that makes me wonder about the viberation dambener is the power steering pump pulley and belt seems to be a little to far out also Thanks again Dave
