Default Pontiac 455 engine build video

Hey all:

I'm producing a new engine building series, the first engine being my own 455 with a traditional cam and compression build-up. Part 1 features the initial teardown and inspection of the short block.

Subsequent chapters will be the inspection after cleaning, machining, assembly, finished with a dyno test and road/track testing to document the power and performance.

Let me know what you think and what should be done to make this video educational series, geared for novices and technical schools, better.

Thanks,

Aguila1.

Default Vimeo Video in 1080HD

Thanks!

Here's a little preview of the engine build and background...

I rebuilt this engine with Pontiac guru, Steve Norwood, back in 1998, pulled from a Bonneville or Grandville of 1972 vintage. It served as a daily driver for many years, trouble-free, mild with 6X heads it produced a measured 200 rwhp on gasoline, good for around a 14 second 1/4, 0-60 high 5s, with 2.73s 700r4 drivetrain. The last two years I've run E85, rwhp around 173.

This time around I'm building a traditional cam and compression rebuild, hoping the 12:1 compression (maybe higher) and RAIV cam will wake the beast. Compression comes from 1969 #16 heads w/ Ferrea valves and 1.65s, assembled by the Pontiac Dude. Durability is built into the motor with Pro-Gram 4-bolt billet main caps, Crower Sportsmen forged rods, and Ross forged pistons. I plan to reuse the stock crank and RARE manifolds along with my worked to run on moonshine Q-Jet. This build will be fully documented...

So stay tuned!

Part 4 is online, prepping the connecting rods.

https://vimeo.com/63287673

After part 3, I ordered the Ross/Butler flat top forged pistons that should produce 12.68:1 compression with 66 cc heads. Butler recommended Johnson lifters and not Rhoads, so that one aspect of the plan was changed.

Not much feedback here, but an update:

We're already up to part 12, a continuation of the assembly process begun in part 11:

Part 14 covers checking over the assembled heads, measuring the spring height and pressure, cc'ing the heads and calculating the engine's compression ratio.

Please note that there was a minor assembly error in Part 13. Can you find it?

This weekend - bench testing the engine to break it in. Next: Engine dyno session!

No, I'm the owner of the 455 and video producer.

In part 13 he accidentally put the thrust plate on backwards.
