Dear Sprint racer 33
Wauw, it seem the new rules for this year are offencive language, actually don't think that this new rule is very constructive at all, liked it more as it was before.
Coming back to your first post your telling; My head is not dowelled to the block as this is only necessary when using over 8,500 revs/min regularly.
So I could have seen it that in your words we where wrong by doweling a head in a professional way.
I came with the question what Sprint cam will need 8500 RPM you even name it regularly.
Now you come up with "up to 8000 RPM" in my view a big difference.
I suspect that you also have seen on the (your) dyno that at 8000 RPM the power is into a down slope for a while, at least with the sprint cams I know, and measured on my dyno.
To be honest I absolutely don't like the remarks about Mr Garrett that I have to tell him he is wrong.
For a start we have always respected that driver, even that much that we have been over to the UK several times in the early 90' to see him race. (there is still a video of 2 different races of him in my foto site, just have a look http://sprint.smugmug.com/Cars/Forum/11 ... 7799_XbRL6
Feel free to contact Mr Garrett, and tell him that we have enjoyed the races we have seen him driving his green Sprint.
BTW Even with my now over 30years of experience with this engine, (and still learning, see our new projects) you puzzled me a bit by telling that a blanking ball was coming out of your racing cranks??? in combination with this obvious high RPM
Very silent now, (I don't dare to advise) we always have replaced them by scrub screws.
