    4.3 liter, the DC-10 of I/Os...

    Every 90 Degree V6 has serious rocking issues, even firing cranks actually made it worse on some of them. The 60 Degree V6s usually suffered from not enough Space between the Heads for decent Manifolds, especially the early ones. More than once, you would hear someone saying "That's not an...

    Hot Rod Magazine... ROTFLMAO!!!! That is nothing but a Marketing Parrot for Accessory Manufacturers. I used to read that Rag in the late 70s, and never, ever saw anything but Praise for any piece of Hardware they installed. In 1970, they were claiming that a bone stock 350 in a Camaro with...

    4.3 liter, the DC-10 of I/Os...

    I doubt that 300hp can come out a 4.3 unless is spun well past 5000, or has a Turbo/supercharger, or has NOx . Those 4.3s in the Impala/Caprices may have been the smaller version of the Gen II LT1, a V8

    I think the Chevy Small Block is a well engineered engine(I have a 5.7 in my 18 1/2 footer), I just don't think the same of the Chopped 3/4 length version.

    1985 50HP 4-cylinder power loss

    Oops, Blue was used until 84. When people say blue band I just default to 72-79, forgeting the 80 - 83 scheme

    1985 50HP 4-cylinder power loss

    The 70hp of the 70s has its own unique eccentricities because of the 2 carbs for 3 cylinders design I understand the TU encryption, but, Chief Project and KF? As for 'no-no' legalities, both are 2 strokes so it can't be emission related

    1987 MERCURY Black Max SR2

    With differences mentioned above, the XR2 had a Fatter Power curve in the midrange, resulting in greater Acceleration. Both the regular 150 and the XR2 put out 150hp at their rated rpm, the XR2 just burning a bit more fuel doing so
