2 barrel with stock exhaust??
I have 72 demon with an offy 4 barrel manifold and 4 barrel carb. I personally feel the 4 barrel is a waste with the stock exhaust but it was set up like that before I got the car. It runs but not very good but it really needs a tune up.
So I am thinking to replace the 4 barrel setup with a 2 barrel set up and replace the timing chain and tune it up. I am not sure if even the 2 barrel set up would be a waste on the stock exhaust. However I do not have headers and headers are not currently in the budget.
Would a 2 barrel have any or much more scoot over a 1 barrel with the stock exhaust?
The car has the original 7.25 rear and floor shifted 3 speed manual with 195/70 R14s, everything is pretty much stock.
I wouldn't give up on the 4 barrel set you have yet........
What it needs is more flow out of the exhaust to make it work well.
Seeing that you are a hands on type of lady that knows how to weld and tinker with things, I wouldn't hesitate to take the exhaust manifold off and ''split'' it, that would give you a lot more exhaust flow and if you don't want to do that, take Rusty's advice and hog out the exhaust and put a bigger head pipe on.
There's lots of info on slant6.org on how to do this.
This is a lot like ''Dutra Duals'' except a lot cheaper.
Also, the carb on the 4 barrel intake should be small, say no more than 400 cfm for it to work on the slant.
A friend of mine had roughly the same set up as you and it worked well and I bet he gained 40 horses over the stock 1 barrel and the stock exhaust.
You really could feel the difference.
Of course, the tune up has to be addressed first........
