crower and Manley cranks were for 40+ years the stuff racers used,,, are they still made in America...i still there out there and not toooo expensive,, please dont tell me i should buy eagle or scat...i am talking American made cranks that were the benchmark for as long as i know..

 

The Crower stuff is. Very good stuff 1800-2000$

The manley i dont think are anymore. 650-750$ range which is same as all the import stuff

Howards and callies make premium sbc american cranks.

Callies also makes compstar which is forged overseas but finished machined here in the usa
Also great stuff. I ran one to 1400 hp just fine

Lunati makes american crank to, in their premium forged stuff called signature series

American stuff is expensive tho, 1500-2000$ either way generally. Howards may be abit less, i am not sure. Callies and howards used to make a dragonslayer crank that was 1000-1300$

 

I had many Eagle cranks in my engine. Never liked them. Went with a Howards crank and I-beam rods and have never had an issue since. The Howards billet I-beam rods are lighter than Eagle H-beam and much stronger.

Where it's made doesn't mean much any more. A crankshaft can be cast just about anywhere in the world then shipped to a manufacturer for final finishing. Lots of parts may be labeled as machined in USA, assembled in USA etc but that doesn't mean the parts themselves were made in the USA.

 

i see Manly rotating assemblies for around $1700 to $3500 or more,, the top shelf scat stuff really isnt that much cheaper and we dont hear much about manly buy some good engine shops offer a set up for how ever much and and for $250 or so they offer Manley,, scott Shafirof does i know of a few others.

it must still be good stuff.

 

i did see a probe video on you tube,, the guy shows their forged pistons get sent out in several different make packaging...possibly speed pro,,federal mogal..KB hypotectic stuff etc

they also claim to buy in billets and make cranks on a cnc for many brands...interesting..

i see Bryant cranks second hand are a good buy at under $500

 

It works well but it likely isnt american forged. But that doesnt mean its bad either

Scat is actually pretty decent. I ran eagle forged crank and rods as well on a nitrous 383. Was good stuff

All depends on what you are doing. Basic na or mild power adder stuff, the china forged stuff aint bad and work well. All out top of the line endurance stuff or all motor stuff using light cranks, or big power adder stuff go american forged

 

I am looking at a new motor to replace my 400+060 2 bolt setup that currently runs 13.0@ 105mph with 3.44 diff and 2500 stall th350.


400 blocks are no longer made so we go the next step a 4.125 dart shp and run a 4 inch stroke and 427ci.. to make good with my 3.44 diff and no power adder we will run a smaller cam and make 500+ hp and 500+ftlbs torque under 5500rpm.


i have a great engine builder and i will go with even one of the good GMPP cranks and i can pay a little more.


The engine builder mentioned that he sees guys turning up at his shop with $700 rotating assemblies and expect wonders,, he said these cranks are like $300 and wont last.

 

I am wearing chinese LEVI jeans, chinese NIKE shoes, using a chinese DELL computer and a HUAWI chinese cell phone and still i go to chinese restraunts to eat. I am Over these chinese products. lets make someone else some buisness.


I will say the parts are 1/2 the cost they were 20 years ago where a set of Arias pistons "could" cost $1000. I also think a lot of old American companies from the 1970,s who we see now popping back up again re booted their companies by moving to china. old names like Jahns pistons, General Kinetics, Racer Brown etc.


Some of the big names in crate motors are using all chinese stuff re branded.
I mentioned Probe industries pumping out Forged Pistons by the dozens and packaging the same item in different boxes for different customers. Its on their website shop tour.

 

Yeah most cast cranks are that cheap and i wouldnt use them. I'd use a stock 3.48 crank before i bought one. I would always go forged

I would seriously consider callies compstar line for crank. For rods with 4" stroke you may have to buy the callies ultra xd rods as they are clearanced for more stroke to give you alittle bit better rod to cam clearance
Thats gonna be your issue...cam will have to be small base circle and small in lobe lift. I dont like doing that but it is what it is. Cam selection will be abit more critical for lifter and overall valvetrain life

I would consider the more common 3.875 strokes and do a 414-420" motor

 

as far as what we use we still have not got into detail...i rang the engine builder i will use and he will call the shots and i will get the parts from america and we set June 2018 to bang it over.

the guy i use will breeze this one in and while i dont need the engine below its a good sign and i look forward to the step up.

this guy just built another 7000+ rpm 355 on pump gas for a circuit car...using all GM parts pre 1975 for the class racing.. its on you tube i will send the link and it pulls 640hp in race trim with a carby on 92 fuel. and ran all season also broke lap records, set fastest time and won the series of 11 races never missed a beat.
