    You do realize that the blower belt should run on the inside of the tensioner pulley, right?

    Dode Martin built the engine and he ran the belt on the outside of the tensioner pulley. When I was at Dodes birthday party the three dragster's there to cackle all had their belts on the outside as well as numerous vintage pictures I studied while researching my build. IMG_1984.JPG

    image.jpg I have a 327-365hp in my 56 Chevy, and just love how it performs. It's been overbored to 331 cui, the heads- have been cleaned up a bit. I also have a 283 punched out to 4 " that will go in my 53 Chevy gasser project. And a few spare 283s and 327s stashed away in my shop, for projects to come.
    But the 301 for the gasser is living in my living room right now....

    My favorite Small Block Chrysler is the 354 Hemi.

  9. The geometry does not work any other way with a Gilmore belt and 671. The belt would cross the center of the engine and anything in the center would be in the way.

    That's where mine is.

    On a blown Hemi, especially running it on the inside of the tensioner would cause it to collide with the water pump pulley.

    The smart money had to be on the 327 in this crowd, and were I to do such an engine it would be 331 cubes and set up for "pucker your ass" RPMs with a lotta cam and all the compression you could muster. However. backed into a corner and made to pick from the list? Sorry kids it's gotta be the 350. .030 over makes it a 355 and it's just enough to jamb in big valves with little to no shrouding, squeeze generous compression thanks to the bore and stroke, give it a modern hyd. roller cam, top it off with either 3 well sorted 2GCs or a nice old school Holley capable of genuine CFMs exceeding 780. Pick the right damper and head configuration and who'd know the difference between that and a 327? Only your hair dresser (or wig maker :eek:) would know for sure. Unless you were a stellar judge of big TQ by the seat of your pants the performance would make a believer of anyone. Still not enough? Spray the bitch! That's right, "Juice", "Squeeze", "the Hose", a "Blue Bottle Tune Up". Imagine that little bastard stuck between the rails of a 39/40 coupe, a well sorted chassis that focused on traction and brakes (gotta stop, right?), looking to all the world like an early 60s hot rod. The guy with that new Mustang or Camaro and the payment book to go with it would never know what hit him. Who's in?

    How come when we built them before 1967 they were 301's but when GM did it they were 302's....guess GM just didn't want to be associated we us 'bad seeds'....

  21. The reason is that the manufacturer rounds the number up (301.6 becomes 302) and when one over bores a 283 or de strokes a 327 the number is rounded down to 301. Its to denote a factory motor as to a made up from another even though they may be exactly the same.JW

    It's actually a 301.66 so closer to 302 than 301. Also Chevrolet didn't want people to think it was smaller than the Ford 302.

    I don't think Ford had a 302 when Chevy brought out the 302 Z-28.

    The one in my car. Cause it's way more fun to drive than to have to push it everywhere I want to go.

  26. People bad mouth them but a 305 SBC cleaned and dressed up nice makes a perfect engine for a light weight car.

    If you can find a clean one cheap buy it.

  27. 64vette1972.jpg I've used all of 'em in everything from a 64 'vette to a '49 Jeep wagon. My favorite was the 365 HP 327 in my 64 corvette with a 4 speed and 4.10 posi. What a ride!
     
  28. I always build my own engines, I still have an assortment of cores on hand. My brother has a 327/365 in the corner of my shop. There is a ton of flexibility when diving into a SBC build, that's why they are so popular, at least with me.

    A 3970020 block bored .125 out with steel crank and a 30/30 or L-79 cam and a set of Power pack heads and a 3X2 setup would be my recipe.
     
  30. What casting #'s are the Power Pack heads as in NZ they may be called something else. JW
