Regular unleaded should be fine, but if your engine knocks, deisels, or pings, try using premium or add an octane booster. The Windsor is a good, solid engine that can take a lot of abuse. The type of gas you use will not damage it in any way. The level of octane will only affect the performance slightly.

( .044 inch ) 351 Windsor and 351 Modified for 1978 Ford truck
yes, gt40 heads should work on a 351 windsor. they should work on any small block ford from a 260 to the 351 windsor. Good luck!
probably about 294 hp
1978 engines were set up to run on unleaded fuel. You can run unleaded,,and I would recommend running the mid-grade to help prevent pre ingnition as motorhome engines work very hard and are running at high tempratures most of the time.
I was looking at my Chilton's Auto Repair Manual and for a 1978 Mercury Cougar it only shows a two barrel carburetor for the 351 Windsor V8 engine
There is no such thing as a 2001 f250 351 Windsor. I believe the last year of the 351 overhead valve motor was 1996.
no 351 windsor engine is small block. 460 is a big block
1-3-7-2-6-5-4-8 for a 351 Windsor
Look on the value covers, windsor has 6 bolts. The cleveland has 8 bolts.
Windsor 351, is a small block. 351 Cleveland, is a big block. The 351M, stands for "modified" and is a windsor (small) block, with Cleveland (big block) heads.
1997 was the last year ford made the windsor 351 5.8 liter.
