dyno numbers from my 340 just for reference

not sure what you mean by intake exhaust heat open

i say heads are stock for a few reasons but with out a tear down i cant be sure
#1 stock valve steam seals
#2 had intake off ports look like my drive way lumpy and ruff so no porting done to them and valve steams look old like i would think they would not rusty just old
#3 when manifolds were off ports once again look like my drive way

this car only has 25k on it 3 owners the orginal then my buddy who stored the car for over 10 years and didnt do any thing to it and me so im just taking combined info and making a ruff guess

had a guy next to me yesterday 68 dart 340 he built his motor he knew his cam he said he was 460ish and my car was definitely more choppy and lumpy then his so i fig 500ish lift came

once again i dont want credit thats not why i posted this it was just for info for guys who are looking at doing a pretty much stock 340

one more thing is i know this number is not impressive i dont give two ***** about it to tell you the truth i built this car for the shows and to run to the parts store its a dog of a car in real life to me at least
