My first 340

[Jim13]

Let's play the HP guessing game!

I didn't build this, it is just the way it is coming.

340 engine
dcc 4120231 purple shaft 284 duration, 484 lift
Keith black 9.5 to 1 pistons
bored .030 over
2.02 intake valves in iron heads
edelbrock performer
750 eddie carb
Heddman headers

That is all I know for now. It is in a 71 swinger. My 75 is 3430 lbs with me in it, so this is probably 3230?

Since there are many factors left out of the equation, I’ll be optimistic and say ~220 hp at the wheel. I had a similer engine combo back in the early 90’s that ran mid 15’s in my Barracuda (Bandimere Speedway, Denver C

Sorry, that is all the info I have on the car right now.
I will know more in a couple of weeks.
I don't know a lot about the 340.
