Buddy tells me it's probably the best all around mopar race motor. Another friend runs 9.80's in a demon with one.

The one in my Duster has been together for many years. Requires little or no maint. to keep it going. Have a .613" flat tappet cam and about 12 to 1 compression. Car weighs about 3300 w/me in it and runs 10.50's anywhere. Will be into the 30's and 20's if I tweak it. Great combo thus far. See ya, Ken Michalik

If you consider all the factors in building a performance engine, And plan on using a std port cylinder head. The 470 is THE best combo out there for stock port opening heads. Light bob weight, big bore, good amount of stroke/cubes, ideal "all purpose" rod ratio make this a very good kit. These combos typically work better than they "should" because it is a well balanced combination FOR stock port sized cylinder heads.

i used to put together a 470 for some friends. it was in a '67 gtx, about 3200lbs, with stage 6 heads. ran a few 9.90's at 134mph. definetly one of my favorite combo's.

I paid right at $4000 for mine with bushed lifter galleys and good bottom parts. Went a best of 10.48 at 129 with Indy EZ heads in a 3300 lb car.
I like Mine

I've got one one the street. Even at high altitude it's all I wanted and more. 3800 lbs at altitude and pulles hard at all RPM's. Couldn't be happier.

Great feedback! How much block clearance was involved? Also, I just got off the phone with indy. 1495 for rotating assembly. Not a bad deal at all but they sure are lacking in the customer service department! I will spend the extra 400 and go with muscle motors kit. Just cause my car dont say superstock or my name isnt warren johnson they dont have time for me!

I am in 100% agreement with Mike. Although many people get all wrapped up in 'bigger is better", I still think the 470 motor is hands down one of the best for the buck, and many off the shelf parts are available now as well for it. 451" ranks right up there, and of course the 493 and 511's are probably next on my list of simple but overachievable combos.

I agree, the 451 and 470 combos are just awesome for the price. When I was running high 9's with an Eddy headed 451 and 590 purpleshaft cam I use to laugh at all the 500" Indy headed roller motors running low 10's. Now I have one of those 500" turds but it's finally starting to come around now with a 9.82. I just think the 500" 440-1 motors need alot of compression to really make them work and I don't have the cam or compression to really make it fly.
I think a 470" motor with a real good set of Victors or EZ's or whatever and a 590 purpleshaft can easily go high 9's and not break the bank, also very streetable and reliable.

Yep, the combination is really important. I've seen a number of those 440-1 headed slugs at the track also. Not that they can't be made to work but the 451 or 470 with standard port heads just seems to be a little easier for the average guy to get a handle on.
As for the original question; yes, lots of people have built 470 inch motors over the years. I was building them more than 15 years ago and I wasn't the first guy to do it. Back then we had to offset grind OEM cranks because nobody was making new forgings. These days you can just whip out the VISA card and order up a rotating assembly.

I'm happy with mine. Steath heads, flat solid cam in a 97 Dakota runs low 10s.

Is anyone making off the shelf pistons for the 470 using a 6.385 rod? I have a nice set of Crower rods but after looking at a bunch of different piston manufactures I don't see anything listed. It looks like most of the kits now use a longer rod.
After looking at an Indy advertisement they show their 470 kit using 6.385 rods, but I have not called them to see if they stock that piston.

I prefer a 470 Low deck to a 493RB for the same money. The 470 is a great bucks down combination in both blocks that's real easy on parts and runs forever when carefully assembled...3.90 stroke is the same as a 455 Buick BTW

Wiseco I think has them.That is the same combo in the Duster.I got them from Indy years ago.

Re: 470 lowdeck stroker/ anyone try it? - 01/05/10 12:52 AM
I am not sure if Indy stocks that number. They have some proprietary Wiseco stuff I believe.
KB makes a forged piston that is within .015 of the compression height you would need. I am quite certain you could face mill .015 off the top of those pistons.
Diamond will make 2 changes to a shelf stock piston for a minimal charge. ( semi-custom/stock). If you have some nice Crower rods, then your should put a good piston in it and get EXACTLY what you need with the Diamonds, unless the Indy deal works out.

I`ve got the "old school" kit. Stock off set ground(3.900 stroke)413 steel crank, Eagle 6.385 rods,je 12.11 comp pistons and w/rpm heads it runs pretty good and have almost 9 years in the same 400 block w/same rods and crank. Bulet proof street/strip combo that keeps on ticking.

I agree with Muscle Mike and Todd. Great combination. We have done the machine work on dozens of them over the years with very good results. Good choice.

Before all the new aftermarket parts the 452/470 low deck combination was unbeatable for durability and consistency.

Re: 470 lowdeck stroker/ anyone try it? - 01/05/10 04:44 AM
Competition Wedge,
I realize that custom pistons are the way to go. I am going to be using some custom Diamonds in a 499 build I have also. I was looking at all these parts I have and the only thing holding me from building a 470 is pistons. I have everything to build a mild 470 utilizing ported Stage V heads and a RPM intake. I just don’t want to spend a lot. I would rather save the coin and use it towards the bigger motor.

...using 6.385 rods...
What about all the hullabaloo of rod to stroke ratio? While there are clearly 470s using the 6.385 rods, the shift appears to be toward the longer rod and shorter piston. Any reason for this? Not looking to hijack, just want to hear thoughts since we're discussing the 470s. Thanks.

Re: 470 lowdeck stroker/ anyone try it?(Iam sold on it! - 01/05/10 06:43 AM
Well,ive done the research,got great input from you guys,spoke with mike from muscle motorss and sam from indy. Iam ordering the kit tomorow. The indy kit is on sale and pound for pound mike said is the best kit for stock style heads and he told me its just a great,reliable combo that makes great power and torque. He told to have the crank shotpeened and watch the taper on the jornals but minimal block cearance and it just works great! Thank you all for your help. This is gonna be fun! Anyone got a used rotating assembly for sale?!!! hey,iam cheep! I had to try! Thanksagain! I will keep you all posted. Its a 383,I swear!!!!

BB ? Do you mean B vs an RB ? What headers do you presently have ? Most headers are a compromise so they will fit many chassis and both deck heights , some work better with one combo vs the other . the only company I know of that makes a deck height specific header is TTi , so if you don't have TTi's you should be all set.
If you have an exhaust system on the car with a crossover pipe you will have to modify the headpipes as the headers will be closer together once installed .
