Re: Trailer Killers!
 

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.

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.

All of those two-piece drive shafts: Did those things last at all?

Re: Trailer Killers!
 

No.

Re: Trailer Killers!
 

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.

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!
