4.88 gears and still no power?
 

I have a 92 F150 w/ 302, 6" lift and 35 wides. I just had installed 4.88 gears to compensate for the lack of power but it still doesn't have any (no different than with stock gears). I have had the entire exhaust changed and new plugs and wires. Can anyone figure out why there isn't any power?

Have you done a compression test, scanned codes, checked timing?
Also when you say new exhaust, were the cats done as well?

Compression is good, Codes are good, timing is good and I changed the exhaust from new headers all the way back to the pipes. I was told that my 302 and the tranny are too weak and there is no hope. Anyone want to buy a truck?

Where are you located? 4.88's would be nice in mine.

A little far for me to go. Im on the west coast in BC Canada.
Good luck with it though.

3K?! Damn.

Anyone know roughly how much it would cost to upgrade to a 351 or 400. I was estimating about 4k with a new tranny, exhaust, intake ect... I also have heard that the 92 model is the hardest to upgrade.
