Looking to make my slant 6 a lil' badass for the time being. What are some decent set ups? Daily driver conditions.
For not allot of money they will run well. Head work Offy or Clifford intake,small 4 bbl carb.
If you have a 170,,no headers avalible.You can get the 225 header to work, the front pipe near the steering box will need to be re-worked. Photo is from my 64 Dart.

If you have trouble finding headers to fit your early A (Clifford Shortys being the only ones I know of), another option is Dutra Duals. This allows you to keep your intake manifold heat - a really good aspect for a daily driver. Doing the HEI ingition swap and getting your distributor recurved will also perk up your motor. If you don't mind swapping out the cam, something to let it breathe a bit better will also make a difference. Use the search function on slantsix.org for engine build ideas. The gurus there have done every kind of slant build you could imagine.
Nope, I have done several Slants, you don't have to change the cam(yet).Just making it breath better with a larger carb and a good exhaust.
I did a test with a 67 Dart 225. Stone stock the thing had a hard time to run 90 mph flat out.It had 2.76 rear gears. With $800 of parts (all new) 390 4 bbl Holley,Clifford intake,Clifford shorty headers,2 1/2'' single exhaust with a good free flowing muffler(I used a Flowmaster 40 at the time)a good tune up with a Petronix electronic ignition and worked distributor advance.The car had no problem pegging the speedometer.With the stock cam/valve springs it was done at 4800 rpm.I switched to 340 Valve springs and the engine would see 5500 rpm. The sky is the limit from there.
Could you share the part number of your starter?For not allot of money they will run well. Head work Offy or Clifford intake,small 4 bbl carb.

I would check the gear ratio out back first. If it's a auto I would run 3.23 or if it's a four speed run 3.55. With a two barrel super six intake and a larger exhaust single exhaust it will make a great difference.
Where did you get this number? Are you refering to the factory advertised rating of 8.5-1? They never even got close to that in the real world. More like 7.9-8.0 to 1.[QUOTE="63 Hurst Valiant, post: 1971924136, member: 522 I'm ocd on certain things but with a current worn compression of 5.8:1,
Something like this could make you slant scream.View attachment 1715131997
....have this set-up for my 1985 D-100. Still need to test fit the headers and power/ceramic coat them.
