Thread: Eagle crank and rods in a 4.25-4.375 stroked BBC, good or bad.

Tweet

Should I not be concerned or should I step up to an American made callies magnum, maybe carillo rods? I hear the compstars are a lateral move. I know there are many out there running these Eagle combos, but I want something that will stand the test of time on a strip motor. A dart block with dart or brodix headed monster is my path. These things are too expensive to have do overs but no need in unnecessary overkill neither, if not needed. Thoughts and real word opinions appreciated...

have many H beam with Arp 2000s bolts and 4340 scat crank engines out there at 750to 850hp with no power adders so add 200/400 hp to the shot thats what many are doing with the china parts with out callies or carillo rods .moving up to a callies is about $1000.added on the crank about the same with rods if your going to make 1000to1300 with out NOs then buy usa parts but if you think the new carillos will not move your wrong i rebuilt them fork end will move there better rods Crower or Olivers. the Horwards move to i seen it if your making big power i go to BME rods. but there more to this as you never said what size it is or whats sitting on top of it CID and RPM plays in to this and what power your going to make and power adders your going to use . at this time i must have 100+ engines with scat/pbm .eagle.pep wheeler. manley . rpm. elgin .cat.compstar.ohio crank. other no name H beam rods. but there more to this. knowing to make the part fit is key to getting it to live, lack of knowing how to set the parts up when you pull it out of the box. even the best parts can fail

I always think about the more important issue, is there really anyone in China that I would like to support with my money???? In some areas there's not a whole lot of choice in whether or not to buy import parts, but on these parts there is a choice!

nice to think that way dave if you have the money thats great. many do not .yes it would be nice if eveyone would buy a USA parts thats not really the case . i get the job by building a engine and the machine work were the guy could not afford to build it with out china parts not all come from china there many rebox that the company is from the USA that machine the raw part from china as the cost is less every one playing this game

If I go with the 4.60 x 4.375 stroke, that will be close to a 1000hp right there with good heads/cam and high compression. No power adders, rpm will be what you say it will safely hold. To be honest, I think the 632 street version you sell, but with 12to1 compression to run e85 might be a possible way. I don't mean to offend or insult your intelligence. I listen/read, and try to soak up every word you say as I value and respect your opinion. Enlighten me more, thank you!

Well, if saving a few $$$$ is enough to ease your conscience about buying Chinese parts, good for you!!!!! Personally, I'll wait and save my $$$$ for a bit longer and buy American parts over Chinese parts! I don't really like Japenese or Taiwanese parts either, but at least they are allies and my money isn't going to support a Communist Dictatorship..... But, just my way of trying to spend my money where it at least has a chance of doing something good....

just did a 582 few of them over the years yes your about at 950to 1000hp but there trade offs with cam and lift to see max numbers .will need a good head last one was with profile snipper 375X but the dart 355 cnc can get very close about 870HP with a cam easy on parts

get off your soap box dave customer make the choice not me i like to eat i do the job. i know who rebox .s china parts do you? funny that this all came about so fast ?

How much compression on the aforementioned small cam 870hp? I am seeing guys run the e85 and being consistent. I can't afford 8 dollars a gallon for race fuel. I will have to scrape to get one of these high dollar hi-po engines to be honest, so I realize you save money doing it right the first time and not doing it over, the second time.

Nothing "fast" about it! I never have or never will buy a Eagle or Scat parts...... I've got my principles, and they don't have anything to do with how much money I have or don't have in my pocket!!!!! Not on a soap box, just stating facts...... China is a Communist Dictatorship.

Competition Products also sells some very good crank and rods not made in China, worth looking at! Not a lot more then the Eagle and Scat stuff, but very good quality!!!!!!

Competition Products, that's where I bought my first 502 bbc a decade ago. Came out of a boat, lol. Ran pretty good after loading it up with some aluminum BME rods and some lightweight Pistons for more compression. Ran the stock crank after int bal and my buddy is still running that set up today. Fast forward another decade and I want the longer throw crank so it's a new game to me.

cam s are low 800s and in mid 280s were not hard on springs at 1.7 you will need to keep track of your valve springs .as for alcohol wiseco makes a nice piston 14to3 if you can over look the twain wrist pin ? if you want talk to me on face book Mccarthy performace or just pat mccarthy or PM me at www.mccarthyperformacne.com i am just about done with the bull shit on here .if you want a engine or dart heads or any parts machine work not many can beat the deals i have . i am a dealer for DART and World and many USA made parts and china as well

We've been running E 85 and E 90 fuel both on the street and in drag cars for a number of years, works great!!! Easy to get away with 12.5 CR on the street, been as high as 14:1 on a couple of big inch engines. Big thing is getting the curb reworked to handle the increased fuel required. Can also run a bit more total advance and when cammed properly can bring the advance in quicker and have total advance in at a lower RPM.... If you go with a bit of NOS with E-85, it takes a bit larger jet on the fuel side, too....
