Re: roller dyno questions

Well as long as you’re aware of the limitations, a couple of pointers might help …… Every rolling road I’ve owned had a flexible coupling of some sort between the rollers and the Telma The biggest commonly available rubber ‘donut’ that’s available is off 500 + bhp Mercs, an ‘eight bolt’ design It’s...

Re: roller dyno questions

Good points. I did some online calculations and seemingly the shaft would take it, but not confident enough in that. On the other hand the contact surface is the tire. So I would guess it would break loose before the axle can break, but not sure. Bear in mind these are double rollers and wheel rpm i...

roller dyno questions

As some of you know I'm trying to build a roller dyno bench on the basis of a telma CC300 brake and an old brake test bench. Since I'm trying to convert the brake bench I ran into a couple of issue for which I need some opinions: 1. I originally thought the rollers were drums that had an axle go thr...

Re: Where in the US?

Consider the Texas hill country (stay clear of Austin and surrounds, though). Also consider the East Texas piney woods area close to the Davey Crockett National Forest. You will surely find the place, the natural beauty, the peace and the freedom you are looking for. No state income tax here in Tex...

Re: Well they finally did it

I'm a strong proponent of personal freedom and a small government. When comparing to the US politics, most would even consider me very moderate in my views. But over here I'm seen as on the far right....go figure.

Re: Well they finally did it

owners will need to pay up to £650 just to drive their classic car once a week in London https://www.motorious.com/articles/news/london-sticks-classic-car-owners/ It does seem, however, that if one's vintage vehicle is sufficiently old it will be exempt. https://www.classiccarsforsale.co.uk/blog/ma...

Is there a list with those partnumbers and the respective sizes? Or is there some logic in the partnumbers?

Yes, like that.

SBC bearing question

The following: when building my previous engine I used 2 different sets to get the clearances just right. I mean one slightly bigger and one standard I believe it was. The bigger bearings were some special type of Clevite bearing but I forgot what type they were. Can someone let me know and in what ...

Re: pistons GM 3959456

Some of you will have read previous threads. I have taken inspected the parts of the original block in my 79 vette. After removing the carbon on the piston tops, I found partnumber 3959456. These are domed pistons. What was the original intention of these pistons? They seem fairly high CR pistons (...

Re: pistons GM 3959456

That's what I found: that these were 70-71 LT1 pistons. Hm, quite strange that these ended up in my engine combined with the 292 heads.
