I need to know what cars in 1969 came with a 351w 4v. I need a 28oz flywheel to use with my T5 in a fox body swap, but the button pushers at the local parts stores have to know what car the motor came out of to even look it up. I told them I need a flywheel for a 351w with 157tooth count, and a 28oz imbalance............they looked at me like I had 5 heads. Whatever happened to guys at parts stores that actually knew about cars? Anyway, hope somebody can help here.

A 69 mustang with the M-code engine is a 4v Windsor motor.

Also look up a 79 Stang with a 302 and a 4 speed. That one WILL be what you want. The 69 351W 4 bbl may have had a 164 tooth flywheel. Look up the stock clutch size for it. If it was bigger than a 10.5, then it definately had a bigger flywheel.

all 351's had the 164 tooth flywheel in 69 and most other years as well. any pre 80 302 will have the same balance and will work just fine. so maybe even a 69 302 with the 157 would work, if they made a 302 with 157 tooth flywheel anyway.
