identify 302 or 351??
Wondering if I could draw on your knowledge...... I purchased a 1986 F250 4x4 that is on propane. The decal says it came with a 5.8 liter. The truck does have a small block with a 4bbl intake and holley carb + propane mixer. Electronic ignition but no fuel injection hardware to be seen as would be on an '86. Is there a way to identify the motor and it's size?? could it be from an early 80's mustang or??? it is a ford 4 barrel intake manifold. I know that was not something that came with this truck. Are there any numbers on the block or heads that could identify?? Any info would be very appreciated! cheers...Steve

Hey there nanaimobarz and welcome to FTE!
If you have your title, check the 8th digit, letter or number. From what I read, it's more than likely a 5.4 and it should be original. I doubt it if someone took a Mustang engine and converted it to LP.
They were offered from Ford though, in the H-D Truck lines.
Get back to us with more info. Please...
Talk with you later....

Welcome to FTE!
As a means of quick identification between 302 and 351, just look at the distributor base. If the block steps up about an inch behind the distributor, it is a 351w. If the block is flush behind the distributor, it is a 302.

More than likely, what you have there is a 351w. You can check the drivers side valver cover too. SOmethimes there's a sticker there that says what the engine is. Mine is the same year/model, has the 4brl. intake and Holley just like yours. So it's most likely the 5.8, H.O. EFI was a higher class option in '86 and the big crossover to EFI didn't take place until '87.
