Get some 3.73 or 3.90's, along with a custom tune from Nelsons. The sluggish feeling is TQ management. Nelsons will eliminate some of it making driving a lot funner

When I installed my electric fans, it felt like the throttle was more responsive.

tune will help, but a new converter will certainly help as much.

Does Anybody Know Why The Throttle Response Is So Bad At Idle I Can Get On The Gas And Back Off Before It Revs

What mods can I do to give it better throttle response? Seems kinda sluggish right now...
One thing that improved my off idle throttle responce was a set of good plug wires. That initial tip-in is pretty responsive, and it takes less throttle to get rolling along.

I also like the stock airbox for low down throttle responce... I tried a few different configs, and I just like the stocker with a paper filter, or a drop-in if you've got a few mods. (I didn't notice anything from my drop-in until I got the exhaust on - and then it was only just a slightly revvier feeling top-end when I'd wind out first gear).

The cam I just put in rev's real quick in park or neutral, and throttle responce is sharp above 1,500rpm. There are some other grinds that I'm sure would extened the power lower if you want to keep things close to stock feeling - just stronger.

Cool....what wires did you get.....I'm about to have to replace my plugs and wires....I am probably going to go with some ACDelco Iridiums and some MSD 8.5mm wires

I've got MSD 8.5's on there now, and they work great... I had Taylors, but I kept breaking them when I'd pull them off the sparkplugs. They had weak crimps down there.

I've got those NGK TR55's, and I couldn't tell any difference with them - I just did it because everyone else was.
