Re: 464 to 470 Custom rods,maybe pistons depending if you can get rods to accommodate the pin placement. Also machine work for the new rods, balancing the rotating assembly, new rod bearings. But I ask, if going to 470 why not 482, same parts same machine work. I build 482 when I have some one ask for a stroker. Gary
Pistons and Rods Existing crankshaft can be offset ground. My new rods allow the use of the original oil pan, if using BBC spec rods, you will have to widen rod throws and most aftermarket rods require an oil pan with a clearance dip in it up front. Use the TA 1511 series at least. JW
Re: 464 to 470 I was expecting them to be delivered as a Christmas present from you Jim. :laugh: Merry Christmas my friend. Gary
Don't forget plug and play rods are available now also that require no special machining of the crank. For the 464
Gary or Jim, The TSP website shows what it takes to produce a 470 in detail. What does it take to produce a 480 displacement? Greater offset grind on the rod journals and rods with smaller big ends?
482? I'm all ears, I wanna know more on this one to. The 470 build was in excellent detail. I loved it. Yes I made a few suggestion but after what I learned? No need for longer connecting rods. Jim, are considering having a good crank made for anyone wanting to go to 470 in a aftermarket block?
Yes, the 482 is a 4.050 stroke. It takes the rod pin down to 2.100 or SBC large journal size. I do beleive every SBC ci combo that came after about 1967 had that journal size, so rod bearings are plentiful and cheap. The 494 goes farther, to a 2" rod pin, and a 4.150 stroke. That's the small journal SBC size (265,283 and some early 327 engines) Reducing journal diameter and offset grinding does two beneficial things.. it adds CI to the engine, and reduces bearings speed. There are plenty of opinions out there as to if this really makes much difference, my recent foray into the 470 was more about building a technically correct shortblock, for less money, than using available Buick parts. The landscape has changed since then, as vendors react to the success of the 470 as they should, and overall we have a lot better options available now, than we had when I started building Buick motors in the eighties.

Jims narrative on whats necessary is correct, and if he puts together a 482 kit it would be easy and less expensive than it is now. I've done 470,482 and 494's, in my experience the 482 seems to be the best, little if any difference to the 494 and the crank is weakened more due to the more offset grind. The machine shop has to know what its doing though, the important aspect of offset grind is to get the new filet correct, seen several that were butcher jobs causing failure. Then the Buick crank was blamed, wrong, the machine shop should be blamed. Jim knows how to do these grinds,as does mine, and I don't think hes had any issues.Maybe he can do a 482 kit that includes the crank. gary
Thank you, gentlemen. I have a couple questions related to the subject as it applies to my engine, but I'll ask them in another thread rather than continuing to hijack this one.
Exactly the same as my new 470 Rod. Just a 2.100 BE. .990 pin 6.800 C-C Buick bank offset Buick BE width ARP 2000 bolts standard My 470 rod weights in at 755 G. Compare that to 805G for a BBC eagle rod I was using. These 482 rods might be just a touch heavier. Have not seen a final price, but I expect them to be in the $600 range. JW
So an offset ground crank with BBC rods will hit the stock oil pan in the front. I didn't know that, good to know. Thanks. Sent from my iPhone using Tapatalk
Ok I thought I had chosen my direction for my new build but this changes it all! When do you think these rods will be available to purchase? How much would a 482 stroker kit be?
See my post called "another 482". Would be a little less if we were doing 2 or more at the same time. gary
Ok thanks Gary, so we'd be looking at about $800 for the pistons, $400-500 for the offset grind and hopefully around $600 for the molnar rods per Jim?
