    Hi guys,

    I just heard from Tom Molnar that our 482 rod we have been working on is now available as a raw forging. There are currently 8 sets available for Priority finishing, which would put them on your doorstep in early Sept, for $640 plus shipping.

    Standard production price will be $595, it will be later this fall before they are available regularly.

    Tom is willing to expedite the finishing of as many sets as we need, for those of you who have been waiting.

    I need to know how many Priority finished sets to tell Tom are needed by Monday Night, so he can put the proper wheels in motion to get them done later this Month.

    are u talking about for a Tomahawk or iron block?

    Most Tomahawk builds are over 500 cubes with billet cranks that can have the rod journal size made for a more common rod, so now what do you think the new rods are for?

    I'm definitely in for a set Jim.

    im so sorry not to be sorry but sorry for sorrys sake. Derek..........Im only on my 3rd level of performance Buick Building. Thats Stocker, to performance , to high performance. Ive yet to enter into the Max performance . that will not be until I enjoy and abuse the hell out of my high performance motor. Im thinking that a 482 Buick would cost in stregthening about the same as a Tomahawk. Im starting my piggybank now. More like a BIG PIG bank. A 482 would seem to me to be something for a Tomahawk. My final destiny is to have a Tomahawk in my Riviera with Wicked Wedge heads. Thats after Jim W does all the testing and kink ironing out, and I ask a bunch of strange but well thought out questions.

    Are the 482 rods for the aluminum bull dog block?

    Iron block, Hotrod.

    Please don't use the name bull dog when referring to a TA Performance Tomahawk block.

    So sorry how sorry you are for sorry's sake.

    Anyway, the 482 rods will have the big end the sbc rod journal size and will use sbc bearings. A sbc rod journal is 2.100" while the BBB 455 is 2.250". Offset grinding a factory crank the extra .150" to 3.90" + .150" = a 4.050" stroke will yield 482 cubes with a IIRC 4.350" bore diameter.

    Can a factory crank be used in a Tomahawk? Why yes it can, but with the capabilty of using a BBM crank forging to grind a BBB crank with 3.00" mains instead of the factory 3.250" mains, someone with a Tomahawk block can go with a forged crank for extra reliability that a forged crank offers for a performance build. So using a raw forging from a BBM crank, the crank can be machined with a lot more stroke without having to decrease the rod journal diameter that the "new" rods are being made for.

    Hope this clears up any confusion, I'm not sorry!:D

    Alrite whats a BBM, crank. I know the BBB, even the BBW:) And no you have only somewhat scrambled my thinking , and whats IIRC?
    I just recently found out about how to use Giffs on a so called smart phone, so Im not too keen with the text lingo. But seriously im going to read your last post a few more times and hopefully grasp the concept. Im actually reading it while typing this and have to keep backspacing. You cant mean big block mopar. Can you?

    Yes, big block Mopar.

    IIRC = If I recall correctly.

    What are you machining on a crank to to increase stroke? If your not machining the Rod journal? Or is it that a BBM your just widening the bearing journalfor the rod. Whats the savings in cost verse the TA billet crank, or geting it from ware TA gets it. Are there any issues with balancing using a BBM. Flywheele. Torque converter hub?The crosshatch on the seal surface, or is that a rope seal deal .

    Billet crank is rite at $4k
    Crower Forged is 2200+ depending on options

    A machined Mopar crank IDK, I do know that a BBM Eagle crank is $850 and then there would be the machining cost,..

    Nailhead crank can be machined to work also it's forged and plenty strong $$????

    Stock crank is a very strong piece especially after polishing the throws and nitriting. Biggest drawback with it is the 3.25 mains and the problems that causes as the RPM goes up

    I went with a center counterweighted 3in main Crower Enduromax for around $2600 for my Tomahawk

    I plan on buying a set just to put on the shelf so I have them in hand when I finally get to build my new short block, but that's a ways off so I'll pick up a set later. Zero rush here.

    That's no problem Shawn... just need to get a head count for those that want them asap.

    I need to know by tonight.

    The Crower is the BBM(big block Mopar) raw forging(before any machining) I was referring to that Crower uses to make a BBB crank. That's why you can only get it with the mains at 3.00" the largest diameter, any bigger and the forging die would need to be altered. Then every time a BBM crank was machined there would be more machining required adding to the cost for the low quantity of BBB cranks bought compared to the BBM cranks sold.

    I need a set. Also pistons

    Will these new rods require the big end journals widening when ground like the BBC rods you were using in the 470 motors? How much will it be moving the pin up on the pistons? Was thinking of a 448 similar to Eduards with my 430 block but now liking the idea of 459 cubes - 4.250 x 4.010. 4.59PM shut the door at work & go play

    I'm going to say no as these rods aren't BBC rods, they were designed for the Buick crank other than the big end bore. I might be wrong.

    The center of the pin bore to the top of the piston is the compression height. That is set when the piston is manufactured. The Diamond pistons Jim uses have an altered compression height to minimize block decking to get to 0 deck. The Eagle BBC rods in my engine are 6.800" long. Not sure of these. Being Jim can customize those Diamond pistons, I'm sure he will have a piston with the appropriate CD to work with these new rods.

    Jim, being that you're going to be grinding my crank and I can use my 6.800 rods in my Pontiac motor, would my current 470 pistons work with these rods and the crank youre going to grind ?
