I guess a few persons wanted to check out the specs on the 409- the original cam in a '62 380 or 409 horse engine ended in part #930, it had .439" lift on both valves.It was a carryover from the small port '61 360 horse 409. A running change was the 3830690 cam, it had .507 intake lift, .519 exhaust lift. NHRA let you use it without any horsepower penalty. The '63 engine used the same cam, but it didn't seem to get a horsepower break, the engine was rated at 400 horsepower or 425 horsepower. The only difference between the '62 hi po 409 and the '63 was the chrome valve covers, air cleaner, and dipstick,and the '63 cast iron exhaust manifolds were a cast iron header that did work better than the 2 1/2" outlet rams horns on the '62 motor, but you wouldn't use either one on a race car. The '62 engine and car is the one to build.The two engines allow the OEM head, the #690 casting, with the #583 head as a legal replacement. The 583 came on the '64 400 and 425 horse engine and the '65 400 horse engine. Only difference was that the valve spring seats were deepened and taller valve springs were used on that head to eliminate coil bind and to enhance spring life. They are more rare than the 690 heads. Have fun rounding up all these parts, and building these engines!! Oh,yes, the dual 4 barrel intakes are the same for all years.

Something interesting is the '62 380 HP-409 is factored @ 365 NHRA HP and the 2X4 409 HP-409is factored @ 370 NHRA HP.
The 1963 engines with the same engine specs are rated at a 400 HP ( 365 NHRA) and 425 HP ( 385 NHRA)
All are Stick shift... Wouldn't the 1962 409 HP 409 with 2x4's be the one to run? (370 NHRA Factored)

it looks like the one, Adger. I think they all need charity, after all, these are obsolete pieces, including 55-57 Chevy's, Fords, etc. If people have this stuff laying around, why not entice them to bring it back out. I don`t see any harm. Maybe I`m wrong, but it looks like it could be done with the stroke of a pen. Like Billy said in another post, Local Track owners would love it.

They were gone after 1960 in Pontiacs.
You could ask Denny Ford or Aubrey Bruneau about the Chevys.
I don't see where they would be a big problem in today's Stock Eliminator world.

Mark,
Do you remember Don Scinto`s Pontiac wagon?
I only heard stories. Ran Super Stock, because you could change the small cam out of the low HP 389?
Perhaps you could elaborate

1958 to 1964 were the X bodies.
1965 to 1976 got the larger H-Body

1977 to 1996 GM stayed with the 1964 GTO/Chevelle chassis design.
Malibu's became Impala/Caprice//Bonneville/Roadmaster/Caddy/Olds
The Wagons had the Boxed Frames.
Police Packages got the all the Chassis attach points bolted.

Don`t recall what it had to weigh in at, but 15-20 years ago, Jeff Davidson raced a early 70s Olsmobile Vista Cruiser station wagon here in Div.6, in SS/MA. To run that low of a class designation with a 455 cube engine , she had to be rather porky!
