I've got a 1975 2.0 engine on carbs.

Engine is in good shape, but I might go to a 6 in the future. In the mean time where are the biggest HP bangs for the buck for my 2.0?

(Assume everything is stock other than the carbs, and going back to fuel injection is not an option)

Thanks in advance

tune up and valve adjust

back date the heavy bumpers

get non '75-76 heat exchangers/exhaust.

Weight, both yours and the car.

Given the stock HP numbers every pound of weight reduction will give you free HP ...

The car will be a fibreglass fender& bumpered GT so weight is gone ( and I'm skinny)
So, what can I do to the engine short of a fire breathing monster?

My last one was a Raby 2316, but I don't want that level of investment, I just want to wake it up a bit

Maybe take a zero off the price of a full blown RAT motor

Looking for engine ideas. What do they respond best to?

I could go cam, heads, displacement and compression but together that gets pricy. What my incremental staring point without diving into the deep end again?

The header and carb tuning suggestion is a good example.
I'll do that. I might even stop there

What's next just above that.

Just cam? Clean up heads? Is there much to be gained there alone or will it require a bunch more parts to make the cam work? Or is shaving the heads for a small boost in compression a better idea than a cam?

Other? Or is much more fruitless for the cost/ effort without doing everything?
