i just picked up a 5.0 , guy sais its out of a 91 t bird or mustang, the valve cover reads FK 8k32aa+10 without taking it apart any ideas on what i got?
Either way its going to be a H.O mustang or t-bird in those years the tbird will have a upper intake like the 94-95 mustangs
my intake dosent look like that, it dosent say ho on the top, and the throttle body bolts straight to the intake without any angle
well pulled the intake off today, its a roller , on the block only two things stamped 32 and SB, any idea what they stand for?
There is an ID number stamped in the block behind the starter - that will tell you about what you have and what year it is. There are too many interchangeable parts on the FSB to try to guess from what is bolted to it.
Look at the distributor cap plug wires for the firing order. 13726548 is for an HO motor, 15426378 is non-HO.
There's no such thing as an HO block. All 5.0's used the same blocks for all applications. 91 will either have an E7TE or an F1SE block, either of which are roller blocks and are for all intents and purposes the same block. It will have either E6SE heads or E7TE's. The E6 heads will have an "S" cast into the front corner of the passenger side head, outside of the valve cover. E7TE heads will have a "T" in this location. The E7TE heads are preferable to the E6SE's, but both were used on HO motors, the E6's being used only for the 86 Mustang's HO motor, and used on (some) T-Bird/ Cougar, (and on all)Towncars, Marquis and Crown Vic 5.0's. As bmcdaniel stated, the firing order will be the determining factor as to which motor it is (HO or std 5.0)
Differences between then HO and non HO are heads, cam and pistons. But if talking about a 5.0 from a pickup, then just the heads and pistons, plus the intake. All 5.0's from 1986-on used the same block, crank, rods and timing set.
