Default Re: Show your rare chevy parts..

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
