Nice Ride - 1968 Chevelle

Helping out a neighbor is easy when they have a ride this nice.

When Jeff came over and asked for a bit of help rebuilding his big block Chevy engine, it was no trouble for Jim to take a look and give some prudent advice.

Together, they spent four days working on reassembling this 454 cubic inch Chevy, bored thirty over with flat top pistons.

With its Pro Comp aluminum heads with oval ports along with a Pro Comp intake, a nine and a half to one (9.5 to 1) compression ratio was attainable.

The engine had returned from the machine shop in pieces and needed to be completely assembled starting with painting the block. They chose Chevy orange finishing it off with a clear coat containing a heavy gold pearl. This gave the engine block a similar appearance to the car's exterior without the five hundred dollar a gallon price. The pistons were already on the rods, so they assembled the short block, added the heads and Jeff went home to install the oil pan and the intake manifold.

The guys made an appointment with Randy at Wayne Calvert Precision Engines in Denton to test out the performance of the finished product. The dyno session turned into a ten hour Marathon because of small problems that would have taken months to troubleshoot had the engine been installed as is in the car. They were able to achieve horsepower at four hundred seventy (470 hp) with torque of five hundred sixty pounds (560 LB/FT).


  1. Oh, to ride in a car like that again. Just awesome.

    1. Hi Rasma, I need to add some pics of the interior. It is dreamy. Thanks for stopping by. Hop in!

  2. Hello Peg. Thought I would cruise by and pick your up for a malt at the soda fountain, or is that the wrong era. Nice car. Jim really has a talent for this work.

  3. Malt shop is great, Mike, although I remember it as Caravelle's Ice Cream Shop after the movies at the Twin Theaters where I watched Thunderball thirty-seven times. My brother worked at the theater.
    Jim is considering starting a business using a Dynamometer to engine test. He made three videos on building a carburetor and they're really good! Check him out on YouTube under Trippmotorsports if you have time.
