Also--I use a crank shop near me in Quebec for my balancing needs and from time to time I get them to grind or in some cases index/offset grind certain cranks (He is so much better than me at it) and for what he charges to offset grind isn't a quarter of the cost of a good new crank. I'm not...

I can't speak for the OP but in my case... I did it because I have a crank grinder and I had a 383/400 steel crank on hand and I wanted to build something unique for my buddy and I've always hated the stupid 3.375" stroke and I made the stroke to fit the piston and rod selection and I like the...

There is no factory hardening, unlike most diesel cranks. Have offset ground many cranks , never an issue. The 3.915" stroke 471 combo was being done in the 80's that I know of and maybe 70's. J.Rob

Interesting to look at some balancing information. 471 W/ ICON dished pistons and Eagle 6.535" Rods = 2297.5 Bobweight 360 W/KB Hypers and OEM Magnum Rods(lighter than an LA) = 2074.5 Bobweight 426 W/Mahle and Eagle 6.7 Rods = 1941.5 Bobweight J.Rob

Just going off the top of my head since I'm not in the shop. Cam is 256/260 @ .050" .580"/.585" 111 or 106 I think. Eagle 6.7" H beams Mahle 929962575 I think the bob weight is 1850 or 1950 grams. J.Rob

The bobweight is very low--like small block low. J.Rob

Yes I've heard of it. In fact I have one i'm building for my bodyshop buddy's '72 RoadRunner. I turned a 383 forging to 3.545" stroke x 4.375" bore= 426.33 ci. I'm using a 6.7" Rod with a Mahle piston with a 1.32" CHT. < Correction it is a 1.480" CHT-I've got a lot of builds going on--LOL.I've...

It really and truly is probably the most tedious and time consuming operation in the whole block machining process. There just is no easy way to speed it up other than a big $$$$$ CNC $$$$ right angle head and even then the line hone will still be necessary to finish it off. It truly is a HUGE...

Yeah it was $1500.00 nice-but worth every penny. A good toolmaker's vice comes with a certificate of parrallelism, square, true, flat, and a known 2" dimension off the table all within .00002". J.Rob

Agreed--See? Its your fault they're still like this. LOL. JK. J.Rob

Thanks, Here's a couple of photos of the current dilemma. No more bearing tang notches. I will have to machine them deeper. Think I'm gonna go with a commonly available router bit chucked in a tool holder in the mill. Hope I can find one. J.Rob p.s. Thanks for the kind words.

Absolutely spot on. Bearing tangs are barely there-also agree on the off -center comment/ also agree on the--"sort of suck" comment. I'd never use 'em again, that's for sure. J.Rob

No idea--wasn't my call-customer supplied. J.Rob

I overshot the first line hone by a thou and a half and had to cut the caps. I used my flycutter in the mill and this is first thing in the morning and when I should have gone home and worked around the house. The CNC calved on me--so I farted around with it for about an hour before I went to...

You would think aftermarket caps specifically made to employ ARP studs wouldn't have to be machined on the #3 cap for thrust adjustability, but they do. -Annoying. J.Rob

Just wanted to share last weeks work menu. I've been line-honing a little longer than line boring and the two go hand in hand but line boring is seldom necessary. However when installing aftermarket caps with .100"+ to remove line boring is an absolute. Before I was capable of this operation I...

After using those stupid "step-Dish" pistons I have come to the conclusion that I don't like'em. Everytime I have used that stupid design I'm way low compared to my estimates. I think those pistons are barely a step up from a stock piston that's .050"-.100" in the hole even if its only half of...

Helped Nick out twice and met him three times in person--the last job I did I called him for his Purolator account number so I could just ship all of his stuff back--He's VERY different in person. I decided I had no time in my life for him and I figured it was likewise. No harm no foul. My dyno...

Flow rates aside--You cannot match the gorgeous chamber on the TF's or there sweet intake valve shape which in large part results in the killer .400"-.500" flowrates. The most flow I have personally achieved with an Eddy 5090 and the stock valve was 298.5cfm @ .600" . With a bunch of other...

I do NOT know how you do it Jim, I really don't. J.Rob

The Eddy 5090 is probably my favourite go to aluminum head--The 75cc chamber is a real bonus if you can build around it which is easy IMO. J.Rob

Not surprising. Thanks for sharing, J.Rob

Bingo! J.Rob

Agreed. I've had customers swear they can feel a difference--That I don't know about but like you said-I see no real downside. J.Rob

There are some on here in my past big and small block builds. You may find them in my 512/522 build threads I think? I've got a new phone and laptop--so it will take me way longer than I have to find pictures. Sorry J.Rob

Enlarge oil pickup to 1/2" NPT Hemi size and radius all instersections with the backside of a round carbide burr, disassemble oil pump and radius and remove all casting marks with a sandroll, remove oil pump relief valve and polish with some Scotchbrite, enlarge mains 2,3,4 with a long 9/32"...

It actually has 2 blow off valves and they function as they are supposed to which is nice. J.Rob

9psi at the start, tapering rapidly off to 2psi. At the initial start of testing boost was on its way to 11psi at the hit and every test progressively getting worse. J.Rob

Oh I'm sure yours will crowd the 700hp mark from what I have seen. Good luck, J.Rob

I ain't adding jack at this point. I didn't sell, design, suggest or promote this kit. Also this is my second horrible experience with this product. J.Rob
