Over time I've taken the measures below to give my '91 351 more power. All of which gave me significant power gains:

• Advanced 12 degrees (make sure plugs and cap are newish and all firing)
• Replaced clogged catalytic converter (this made a huge difference)
• The gas peddle was actually bottoming out on the floor mat.. which didn't allow wide open throttle. Throttle cable is too long. I wonder how many owners are having this issue and don't even know it.
• 4.56 gears with my 33" tires. While 3.55 with 33" and 302 is not a good combination for power, you should be able to get up to highway speeds fine. 4.10 or 4.56 gears would definitely make a difference but only done last on the list when all other power robbing items have been addressed.

How did you fix the throttle cable? I noticed forst drive that i was bottoming out on the floor.

For some reason the correct length of throttle cable is very hard to find online. Probably why a lot of BKO's are having this issue. All of the aftermarket cables are too long. After exhaustive research For my '91 I found this one but this Ford parts website says it does not fit my vehicle do I didn't get it. Maybe someone here will be able to verify this. 1992-1996 Ford Throttle Cable F4TZ-9A758-L | Village Ford.. I finally gave up searching and just used a steel cable clamp to set where the peddle stops.... Removing the floor mat also helped.
