I have a simple Dumb question. I prob will not do this, but I am just curious to know if this works.

I dont have a water pump pulley for my this 72 302 engine. Anyways, I was curious to know if I could swap the (timing chain cover, water pump, water pump pulley, Harmonic Balancer, and Crank pulley) of my old 68 engine and place it on the 72 front.

why would you need to change the timing cover they are the same?, but yes everything will all swap over as both motors are 28oz balanced motors

Just making sure I am saying this correctly, If I need to I can swap the a 28oz 4 bolt balancer to a 28oz 3 bolt and be fine?

Also, I tried using the putting the 68 water pump in the 72 timing cover, and it does not work. The 68 Water pump has no back and the 72 does.

Anyways... I was looking through my book. and I can not find the Torque for the Harmoic Balancer. Anyone have a clue what it is...

I did find it says about the crank pulley torque is 70 - 90 lbs...

Thanks for your help

rmodel65

maybe 25lbs for the bolts

mstg007

on the big bolt that connects the balancer to the crankshaft is 25 lbs?

It felt like a pain in the butt to take it off. lol

rmodel65

no the big bolt is about 90ft lbs

the bolts that hold the pulley on are about 25


i assumed you had that already since you posted the value above :P
