70 dart 318/904/7.25

Slow down, you are all over the place.......want's, idea's, dreams are causing you great confusion!

what you can do now that is low dollar would be pick up a factory 4 bbl intake out of a salvage yard, hopefully it will still have carb bolted to it, if not look for cheap carb and rebuild it. Put a set of 360 iron exhaust manifolds on it, might be able to get them for free. This takes care of more air in and out. This is easy-peasie simple low buck hot rodding that has been done since the day after dirt was invented.

Next, you could do a cam swap, something on the small side; ask here and you'll get ALOT of suggestions........one that comes to my mind would be a stock 360.

You could have fun driving this right up till you break the 7 1/4.....a less expensive axle swap would be an 8 1/4
