Alright Fellas,

NOTE: I'd like to post this for everyone installing a late 302 in their early mustang. SteveL, I could do a writeup on this if you'd like.

Well, you all know i've got a late model 302 w/ early model water pump on the stand. I originally didn't know of any differences with 289 and 302 water pumps and asked the seller to bolt up an early model water pump (passenger side inlet). Also didn't think there was a pulley issue either.

Well after searching high and low for the correct pulley and FAILING. We thought our next options were to switch back to a late model water pump and buy a new radiator. NO WAY!!

As a last effort to make things work, I called Randy at March Performance and told him my setup w/late model 50oz. fluidampr (same width as stock late model 50oz. dampners) and he recommended I buy the crankshaft pulley part #1614. I received it yesterday and it lines up perfectly with an early model water pump pulley!! And probably the early model radiator and bracket assembly!!

In short, late 302 w/ early model water pump use March crankshaft pulley #1614 w/ early model water pump pulley!!

Hmm.. Was your balancer a 3 bolt 50oz or a 4 bolt 50oz? Also, was it thicker or the same size width as the original 28oz. balancer?

I have a 4 bolt 50oz Fluidampr which is thicker in width which pushed the crank pulley out too much to line up correctly with the water pump pulley.

later model 302s are usually referred to as 5.0s too

Hot 'n' muggy ... just like LA, where I was just four days ago. The good thing is we have typhoons to clear the air!

Used a 3 bolt 50 oz damper that was exactly the same size as a 68 302 damper. Lined up PERFECTLY. From Total Performance in Mich.

Hey Mellow,

Are the '68 302 dampers smaller in width? Sorry, don't have much experience yet. Just curious to know.

Hey Simon,

How often do you go back and forth? Looks like the 2nd or 3rd time i've noticed this year.

rockafellz,
Let me know how it all worked out on the pulleys. What year water pump pulley did you use with the March pulley? I have the same problem with my 331 stroker. The 4-hole fluidamper sticks out about 1/2" further than the water pump pulley. I have aquired a 4-hole single groove pulley set from a 69 302 pickup but the water pump pulley is too large. Is this the same crank pulley or is it different from the March pulley? If so, I might try to use a smaller 289 water pump pulley with the 4 hole crank pulley.

Hey Bluestreek,

Here's the configuration...

-'87 302 w/4 Bolt Fluidampr (thicker than original 289/standard width for later 302s)
-Early model water pump with inlet on passenger side
Pulley Configuration: Use early model water pump pulley and March pulley part # 1614 (single groove 5 1/2" diameter)

The late model 302 crank pulley is too big (8") and will hit and not line up with anything.

The other option is to use the late water pump with a new radiator (staggered inlet/outlet) !! Too much money in my opinion.

NOTE: March pulley #1614 is 15/16" of an inch from the fluidampr plate to the center of the belt groove.
March pulley #1532 is 1 1/2" from the fluidampr plate to the center of the belt groove (only use this if you have a thin balancer).

Erik

That damper has a width/thickness of 1 3/4" from front to hub. Jt went out and measured it. It's out of the car.
