Researching Ultrasonic cleaners and CREST Seems to be the best but they are very proud of them.
Big models cost thousands $$$$.
Fleabay China models are affordable .
Found a 6 liter model for $161.00 Free shipping.
200 watts of sonic cleaning power. Heated also.
Post a picture later.
Have lots of small parts to clean. Be a real time saver having a Small Sonic Cleaner at home.

yea man i mean a little cheapy piece to do small parts like rocker arms and valves and stuff would be nice... think im gonna try out that cheapo harbor freight one for just that purpose.. but it would be somethin else altogether to have one big enough for a crank, or a head, or even a block! theres somethin fancy!

There's never enough money to build it right, but there's always enough to build it twice!

Check out branson also look for used on ebay. The specs you need to look at are frequency of sonics the faster the sonics the finer cleaning. The slower speeds clean fast but not as much in the nooks and cranies. Also temp settings are a bonus. Use one everyday at work.

I try and not think about it John.
Thinking Pocho Pontiacs of mine.
Said the hell with Corvettes this year and dickheads.
Racing...Hellcats & SRT Viper T/A To beat .
Midnight Street Race action.

5.0 Gang in Joliet back with 8 & 6 second 1/4 cars.
Rear Diffs to build for them again.
Sidejobs local again.

Build a new garage.

Also thinking of Olds V8 power again.
Have thier own power band with 6 degree valve inclination heads.
Still have my 1965 Olds 425 A 360Hp 470 ft/lb engine & Olds 403.

Economy is slowly getting better some paint work and ink flowing my way. Down the road will build a nasty s475 turbo build. Maybe compound Phil style. Something all race with a plate. Good to see things on the up for ya Brian.

My 1970 455 #1 shown above in 1st two pictures. From a 1970 Bonneville Convertible.
Rated 360 Hp & 500 ft/lbs . 10.25:1 static compression ratio. Real mild 067 cam factory installed.
Bought it back in 2007, 8 years ago now. Drove to Western Iowa, almost near Nebraska in the dead of winter & brought it home.
When it warms up I am going to tear it down & build it too.

I still admire Olds V8's also John.
They make tremendous low end & midrange torque on 87 octane pee water gasoline.
Hold up to severe abuse.
Inexpensive to budget build.
Headers not really needed. Can use factory exhauat manifolds and still responsive.
They pull 2.41:1- 3.23:1 gears with ease.

Oldsmobile did some funky stuff with Exhaust to intake ratios.
39 degree lifter bank angle used come 1967.
Made a mild cam appear bigger than it really was.
Still delivered nice idle.
403 Trans Am was faster than all but 455's.
Disco era.
1971-79.
Only you and me know this John.
Built and driven both.
