1965 dodge dart gt /6

Welcome to FABO!!!

Your question about beef up the /6, or upgrade to v8 is a religious one - you'll find both denominations here.

Really need to know what you want to do and what you want to spend.

V8 will get you more bang for fewer bucks

Some people (myself included) need to scratch the 'what can you get out of a slant?' itch (but I'm covering my bases and doing a small block stroker in my '64 Dart wagon).

Check out the Slant 6 Engines section for more on the slant: http://www.forabodiesonly.com/mopar/forumdisplay.php?f=77

Also, check out the Forced Induction Mopar section for Slant and V8 supercharging and turbocharging info: http://www.forabodiesonly.com/mopar/forumdisplay.php?f=84

Also, have a look at www.slantsix.org for more on the venerable leaning tower of power

Regardless, consider upgrading your brakes first!
