I still disagree! Your throwing around generalities. Be specific!
If a 410 cost $10,000.00 more than a 358/360 then something must cost more. http://riderracingengines.com/engines.htm
Wow, I guess you didn't read my post at all before you replied. I gave you the links to all the bare blocks that a large supplier has available and you ask me to be more specific? Seriously??? I would hope you would have the power to deduce that there is in reality anywhere from a $3,500 to nothing difference depending on options between a iron or aluminum block, but I guess that was too much work and thinking for you to do.
As for what all is being done for the additional $10,000 of work? I would have to guess a lot of it is the difference in the injection. Remember 410s run 16 nozzles not 8 like 358/360 motors. The additional plumbing for the head down nozzles, the machine work to the heads for the down nozzles, the down nozzles themselves, and I'm sure there is more work done to the heads as far as porting goes than a 358/360. I would have to imagine that is the majority of the $10,000 right there.
Most of that is a one time cost though as long as you don't blow it sky high. During refreshes castings are reused most of the time unless warped or the bore in a block is beyond tolerance. Not sure if those blocks can be resleeved or not. I would like to think so but have no idea.
Looking at it that way, yeah it's $10,000 more, but if you take care of your gear you won't be replacing heads or a block every 10 or so races. The cost difference isn't nearly as much when you factor in what you get paid with 410s vs 358s or 360s.
When you sit back and look at it it's pretty clear why the other divisions their car counts are suffering.
Btw here is what Knoxville paid its 410,360, and 305 drivers last year. I imagine our local tracks are probably pretty similar. http://www.knoxvilleraceway.com/Article/1593
