ok here we go ,I have a 1984 f 150,yea its a brick but its got a 357 with a c6 and a 2800 stall converter . my question is should I go to the4.30 gears or stay with the4.11

From 4.11 to 4.30 is not much unless its an all out drag setup... Moving to a 4.56 or lower gear would help move the "brick" (I run a 4.56 in my 69 C10)

going to 4.56 is quite a jump ,I don't think that that would be good for me since I do drive it some distances to shows and cruiseins

I would stick with the 4.11 in that case... No real gain with the 4.30

bumpstick ,4.56 and 30" tires shouldn't be to bad I guess .I was running 4.11 and 27.5 " tires and was turning around 2800 @ 55. So if I stay off the hyways I should be ok right?I just want more out of the hole and shortin my 60' time. I've gota kid at work that needs an attitude adjustment,you know the type new dodge with a HEMI It's a frikkin 4 door turd but he thinks its hot. My best times have been in the 14's gota get better.

With my 4.56 gear and a pair of 28.5 tall tires it does 55 @3000K rpm and according to the calculators it would need 3550rpm to make 65mph...

You could use the 30" tall tires and the 4.56 and keep a pair of 28`ish tall slicks just to cause him heart failure off the line...

That thing has 3.9 gears. They tend to be stump pullers. I have talked to a couple owners and both had tow rigs prior and both said the dodge out pulls the old rig. One had a Chev and the other had been a ford.

BTW, if it has the HEMI decal on the bed panels that is worth at least 100 mental horsepower.

Dont knock the Hemi's too much. They had 4.10 gears as an option in those trucks as well. With a few aftermarket modification those trucks can be made to run very hard.

The amount of worry you should have will depend on the options his truck has (like 2wd vs 4wd, long bed, vs short, etc). A person I know and have raced with ran a 14 flat at the track with his Rumble Bee model. I believe both those and the Daytona models come with very steep gearing.

My opinion . . . it should be a good race.
