I'm putting a 1978 351W into a 1969 F100 2wd with a Borg Warner T-18 4 speed manual. The truck currently has a 240 6cyl.

I bought a new flywheel, it is NAPA part number NCF88116.

So now I have no idea what clutch set to buy. I don't know if I should look at clutches for a 1978 F150 to match the engine or clutches that fit a 1969 F100 with my transmission?

Can anyone please help provide a part number or something for a clutch that would work in this application? That would be very helpful, THANK YOU!!!

 

I think that both engines would use an 11" clutch, check if your old clutch and pressure plate fit the new flywheel. If so, a clutch disc for the 240 would be the right one.

However I see that ebay shows that flywheel listed for 83-93 5.8, so maybe it uses a different pressure plate bolt pattern than the older flywheel. If it indeed is different from the 1969 flywheel things will get more complicated. In that case a pressure plate and flywheel for a 1984 pickup with 351 and T18 I would think would be correct for that flywheel.

 

As Beanscoot said, the pressure plate bolt pattern has to match the flywheel to use it.
