351w swap in to a foxbody
 

i im new here i have a 351w out of a 84 ford f150 goinog to put it in to my

87 mustang going to use my t5 10 spline tranny just want to know what flywheel to use and where to find one i have heard some thing about 28 oz and 50oz but i do not know what my motor had open for ideas thanks

The 351W will need a 28oz imbalance flywheel. A 5.0 uses a 50oz imbalance.

If the fly wheel was still on it, check for a stamping on the back of it.

Buy from Summit Racing, if there is ANY issues, they will take it back. :tup

ok thank you will the 351w flywheel fit in to the t5 or do i need to find a 302 flywheel that is a 28oz i heard that 1980 and up where all 50oz and from 1980 and back where 28oz or im just wrong thanks for your help

thanks for the info

yes I am sure that all Ford small block flywheels are 157 tooth so there should be no problem there. You are right the early year 302's used 28oz imbalance but I have no idea when Ford changed it. If the truck you removed the motor from was standard you might be able to use that flywheel. Just count the teeth. You need it to have 157.

ok cool no the truck i tuck the motor out of was a auto trans

The right flywheel from a Mustang would be up to '82, if I recall correctly. But, that will limit you to a 10" clutch size vs the 86+ 10.5" flywheel (50oz), so when you're ordering a clutch you will have to ask for an 85 Mustang GT clutch. Valeo and LUK both make quality 'performance' clutch kits in 10" size with the right teeth for the T5.
Make sure you install a new oil pan gasket (steel reinforced) and rear main seal, if you're not rebuilding the engine that is......
