So i have to respond to this . I am a sucker for cars that i have actually owned . But i owned a new , well 6mo. old 62 impala SS. 327-300Hp
4spd. 4:11 posi It had the big AFB carb on an Aluminum manifold ,from the factory.With a set of atlas Bucron tires (cadillac-size) i beat every 409 425 i raced. on the street. And i was only a Sr in high school. Dont know if there were other 300horse cars that had the Al intake but mine did.

Not to squelch a good thread, but who was tuning the 409's back then? I had a very stock 409/425 horse that was balanced, OEM replacement cam,correct carbs F&R, 4:88 gears, a Muncie wide ratio 4 speed, fender well headers' one piece drive shaft,10 inch by 29.5" slicks, and it would go 12.70's very reliably, 12.66 on one occasion.
I would leave about six grand and shift at 5300. RPMing the motor actually slowed the car down because the torque curve of that motor was pretty low RPM. We tried a Powerglide with a stocker converter and it picked up about half a second. It wasn't the ultimate horsepower motor, but it ran pretty good for what it was.

All the 409 I saw and raced on the street were single 4 Brl.
409/340HP. The were some real Pigs and easy money.

Even on the street in the Detroit area the Ford 406’s were quicker than the 62 409/409 as very few and had the ambition to pull the heads and get rid of the dual head gaskets and change the factory pistons to the Jhans after market pistons. According to Jere Stahl we’re worth 40 Hp. He was just starting to build headers in his Lenoard gas station in Romulus, mi on the Conner of Huron River Dr and Northline rd.

I was always looking for 300 horse impala's and a sure sign was the 2 1/2 in rams horns.

What vehicles was it available in in 1965? I know the Corvette and I think the Malibu bodies, was it also a 1965 Nova option or a Impala, Biscayne, Bel Air option too? Seems to be an under rated engine from that era.
