Slugs...

Back in the day.. the 340s were killing a lot of other cars out there !! they were as fast if not faster than a lot of 440s!! the 360 with its larger cubes.. DIDNT measure up ot the earlier 340!! As far as the AAR Cuda.. I was smacking them with my 289 in my 67 Mustang.. dont let that AAR thingy think the car was special!! Did you EVER look at the exhaust??

340s were a scary ride back then... but then I'm only 60 and I do remember the 70's !! LOL

Just me....................Been there, bought the T-shirt!!

I had a 70 swinger 340 4spd with 390's. The heads were massaged and had a purple cam. Obviously no traction off the line but still,wasnt real impressed with it. I raced an 85 or 86 5.0 Capri to 60mph.Off the line I just spun then started to catch him.If we were going to a 100 I would have caught him,but I didnt!

Not to mention I never saw a real fast one! Heck I think the 318 Dusters could beat one!
I think the highest HP motor the 340 made was 275!

My cousin has a 340 in his Duster and he runs in the 12's all day... Here is a link to his page, it's french because we live in quebec Canada eh?

Dusters were light. Had similar wieght distribution to chevys Nova. They always made good hot rods!
