My dad once had a Z11 aluminum water pump that he found at Carlisle. This was at least 30 years ago. Had the 0 at the start of the part number. He ended up trading it for a bunch of 65 409 parts. Boy, does he wish he still had it! </div></div>

He's much better off with the '65 parts he can use than looking at an aluminum water pump hanging on the wall that he'd never use! He made the right decision. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Verne would the 409+2x4 be about equivalent in performance to a stock L-78 or L-72. Just wonderin

I experienced a direct comparison with both a stock 2x4 409 and a stock L-78 in the same car with exactly the same set-up on the car. The ONLY difference was the L-78 ran a flex fan; the 409 ran the stock clutch fan. I had no problem shifting the L-78 at 6500 but I was more careful with the 409. 5800 shifts.
Best times:
L-78: 13.17
409: 13.31

Cool. I always wondered about this. Why only 5800 rpm with the 409? Were they fragile, or did they just stop making power up top?

They make good power over 6000 but I was being careful. Pistons weigh almost 2 lbs each! Good blocks are hard to come by.

I only ever heard a 409-2x4 running once so far in my lifetime. The car rocked slightly as the engine idled. Awesome actually.

Thanks. My Uncle (Mom's brother) had a 425/409 in a ermine white, white interior '64 SS back in 1966-1968. He said he used to almost bury the stock (likely inaccurate) 7000 rpm tach when powershifting on the street. He said he tore through 7 or 8 rear ends, but the '09 never broke. He ultimately sold the '09 and swapped the engine for a 195hp 283 so he could get better gas mielage on the daily commute and go class racing in 1969 without constantly breaking parts.

He never had the '09 to the track, just street raced it. According to him, even in the late-60s, the 425hp '09 still was a fast car. He said he only would lose to 440 mopars and 427 vettes. He claims most GTOs and SS396s were no problem.
