Improving my 360 combo. Need advice/input

The gear thing has got me thinking now. I almost forgot I have a rebuilt 8 3/4 rear with a 489 case in my 68 Dart that has 3.91s and a Sure-grip. I could easily swap pumpkins. I guess my only problem is that the current rear-end in the 66 hardtop is a 742 case. Wonder if I would have to get a new drive shaft?

Crackedback you always have dumb questions......LOL.............Boomer

I tell you what. The more I think about things the more options I get tangled up in.

The highway cruising with 3.23s is really nice, 3.91s would sure put you in your seat though. Tough one.

I may take a look at the Voodoo/Lunati cams.

I guess I want something that will kick you back in your seat, roast the tires and have good street manners. I guess I could clone my convertible build. LOL

Would be nice to open this engine up with as little as possible since I have many of the parts needed.

Guess the only thing I really need to buy is headers right now. A new camshaft and intake would be next if things still suck.

Thanks
