Title: 351w swap help
Post by: 86caprirs on March 14, 2010, 05:52:05 PM
I spent the day at the wreaking yard tracking down a 85 Crown Vic with a 351w in the engine bay. I pulled off the ballancer so I could use it on my 96 5.8L engine going into my tbird. When I get home I compare the 96 F-150 ballancer to the 85 Crown Vic ballancer. The only difference is that the 96 F-150 ballancer has a crank trigger on it. Other than that they are identical. Did i just waste a bunch of time getting the older ballancer?

Are you going to run a distributorless ignition?

No. What does that have to do with anything? I heard I needed that 85 ballancer for correct alignment for the mustang accessories going on the 351w.

Im pretty sure that the older balancer will work.  The only reason there is a crank trigger on the newer balancer is due to the engine being distributorless (think 5.0 exploder/mountaineer).  As long as the balancer is the correct oz balance and has the correct pulley holes i dont see a problem.  Someone can correct me if im wrong.

ALL 351w's are 28oz balance. I bought a Powerbond SFI balancer for mine. It's the one that doesn't require a spacer like the FMS and other aftermarket ones.

Yup, would appear so...

I'd never trust a older ballancer anyway, as the rubber is often rotten and the ring can come off...

I just might as well use the 96 one with a spacer then. Oh well. Thanks guys.

On another note I got my intake and valve covers painted. Looks like this april long weekend I will do the engine swap and Mass air conversion.

So I installed the 96 ballancer and the accessories from the Tbird and the serp belt lines up with it all. Today I am pulling the engine/trans from the bird. Then I will spend the week cleaning and painting parts so I can finish assembling the 351w. Then on the Long weekend in April I will put the 351w and aod in as one assembly, then wire in the MAF and repin for the A9L. Hopefully all i will have left is the exhaust system which consists of a dr.gas o/r x pipe, dynomax flow tubes, magnaflow lers, flowmaster tail pipes and 3" stainless tips from Canadian Tire.

The rubbers. I just ordered a set from Chuck. I was wondering if Energy suspension made replacements but I could not find them.

Best money you can spend right there.  Even brand new stock replacements won't last long with the torque of a 351.  I have a set of chucks mounts that have seen 3 different cars with 4 different engines...lol.

Doesn't that '85 crown vic have the oil pan you want?

Post by: 86caprirs on April 04, 2010, 03:06:25 PM
Yes it does. It has the oil pan, pick up tube,dip stick and tube, ballancer and flex plate. But like I said, the 96 truck ballancer was the same as the 85 ballancer except for the crank trigger ring.
