Although a bit hesitant, I am looking at a used 1993 HO motor tomorrow night. It has 80k miles, but I figure the bottom end has to be tight. The top end will eventually be opened up.
I also talked to a guy regarding transmissions. Seems there is a little bit of thinking to do.
"I am planning (next year) to run COMP Cam's XE266HR cam, flowed heads and my current Edelbrock RPM intake and 4 barrel carb, hoping to produce around 300HP. (all specs taken from a Ford site, which got 340HP on the dyno) I'm looking for low end power vs high revving stuff. This is just going to be a mild street build, as I'm not gonna race a family convertible!
I also came across an issue that I was unaware of. The spline on the input shaft may vary on the 302 motors. I also heard that there are different torque converters (drain next to the drive stud and the drain plug in between the drive studs). Since you will have the motor to look at, I am guessing this would not be an issue? Like I said I plan on getting the engine sometime this week.
Another area that worries me is the mating of your C4 transmission and the 1993 HO motor. As I've read, I need to be aware of the flex plate issue: different weight and different number of teeth.
I understand that the later model HO will be using a 50oz, 164 tooth flex plate. Will your transmission be a later model that would accept this flex plate perfectly? I understand there are small bellhousing C4's and large bellhousing C4's. The larger, running the correct 164 tooth count. I also read about harmonic balancers, but I'm not exactly sure how that comes into play.
