deep groove pulleys on 383

I have a 68 327 car that I am going to swap in a 383. I heard the 69 deep groove pulleys might work a little better than the 68s but thinking the alternator will have to be moved. What have you guys used for pulleys when you swapped motors? I guess I better see what my dampner accepts too
Thanks

Your damper shouldn't effect it. The same pulley can be used on 68's (short pump) and 69 (long pump)

Re: deep groove pulleys on 383

Why not use 67-68 deep groove pulleys? 69 pulleys don't work well with 67-68 alternator location just as you said.

The only reason someone would want insurance is if they want to pay someone elses bills or want someone else to pay their bills.

Re: deep groove pulleys on 383

I did some checking off HBC website for ease. The killer on the 68 stuff is the $138 power steering pulley (back ordered) and the only water pump pulley they show is a used one for 324. The 68 parts are alot higher. I might see how the wires to the alternator are ran on my 69 and see if I can figure out how to use the 69 pulleys

Re: deep groove pulleys on 383

If the price of the 68 power steering pulley sounds expensive, you need to price a deep groove power steering pulley for a 69. 1105 prices are are fricken crazy.

Re: deep groove pulleys on 383

if you are concerned about the belt coming off, here is a little trick I use to prevent it from happening. I hit 6200 several times and the belt stayed on

As long as everything is aligned, there shouldn't be any problem really.
My old combo had mid 70's-early 80's pulleys from my 74 Blazer....7500rpm was the norm at the track. (only crank/water pump/alternator pulleys)
