Performance Questions 225 vs. 360

Do some searching here & slantsix.org.

there are slant powered vehicles in the 9's.
a slant will never compete with a 360-- but you can make a slant very nice by modifying it just like any modified engine:
, headwork, better flowing exhaust & well tuned timing & fuel system.

What are your driving habits-- if you want to beat a ricer stop light to stop light-- then it will cost $$.

I would open up the stock exhaust , tune-up the carb & timing & see how it goes, when was the last time the valves were re-set?

And lastly how mechanical are you? motivated with friends & how much $$ do you have-- a v-8 swap is not cheap even with a parts car
the pictures show the 75 duster & the 73 dart sport parts car -- used in swapping a 360 in to a car very similar to yours:

if you have your slant out-- that's the time to work it-- I have a slant head you could have for shipping to modify & less down time for your car.
