Lamar Walden is probably one of the better known 409 builders/modifiers.
LOTS of people talk about the obsolete/slug reputation of the 409----------------------but I wonder if they have priced 409 cars and engines lately!
Oh ya, 30s Fords with ~300cube Flattys, 2-4 carbs, finned alum heads, upgraded distributors and 12volts are also obsolete relics----------------priced 'um lately????? That is if you can even find one to price!
Be careful when criticizing an '09 car!

Chrysler recommended 102 RON fuel or better and that full-throttle bursts be limited to 15 seconds on their 13.5:1 max. wedge 426 in 1963...

That applied to 1962 also. The problem with them was they'd empty the oil pan and pump all the oil to the top.

According to Ray Brock in Hot Rod (January 1963), that 15 second restriction didn't apply to the 11.0:1 Max. Wedge 426...?
(11.0:1 is the one Hot Hod tested). Great article!

According to MikeM, CF, April,11,() my cousin had a new 1962 13.5-1 413. It had the warning attached, somewhere. After he lost two 13.5-1 short blocks, he put in a 11-1 and sold the car.

I have a 413/426 supplement operators manual that specifically has the same warning in it. It was either for the '62 or '63 model.

I don't know but little about those engines but I'd bet both the 11-1 and 13.5-1 had the same oiling system/oil pan.

I read that article you mentioned within the last year. Good article but it didn't really portray how good those cars really ran.

Brock's article details the problem with oiling and failing the rod bearings on the '62. 3 quarts in the top of the engine at high revs. Makes sense the warning applies to both CR.

i had a 63 Dodge factory SS 426 wedge that would spin rod bearings. finally grooved the crank to provide more oil flow, doubled the oil pump (the 426's oil pump was external to the block and could be doubled up like stacking meat on a sandwich), enlarged the pump passages and deepened the oil pan.

kept blowing head gaskets though with the 13.5 compression...

I have had good times with my 1962 409.

Here are several pictures of it.

Sure, let the revs drop a hundred or two at each gear change. Hump-head torque would pull you right out.

That comment was made tongue&cheek in response to the comment that the cars with a 425hp 409 came with a warning sticker about engine damage if run more than 10sec at full throttle. Those cars never came with such a sticker.

Heck, GM sold 15,000 Chevy 409's in 1962. The Corvette seems like a natural for that engine. Was its physical size too large for a late c1 or early c2?

As a young teenager I saw a factory W motored 63 Corvette convert. red & tan. That cars owner & best friend had the same car with the lowest output 327. They would set up a race in the afternoon at Ruts Hut and show up with the W car later to race.

That was a rare car! I think they only offered the 65 that way for a few months til the big block was offered. Would be worth a lot of money today.

Even more rare because the '65 409 was not released with 2X4 intake. Only single four barrel 400 hp.

Yes, 21 was not finished and ended with ramps just beyond Rutts…. easy on and off and more than a 1/4 to the next on ramp…. at the other end of 21 in Newark they raced out of a place called the Dream Boat? i think.
