No, what he said was "these billets good really nice, whoever made them did a good job". The other thing he said when I asked about custom masters (and Ernie will love this) is normally I have a master for any engine request, but in the past when I get a mad scientist type customer who wants something cutting edge or way out there I just send out a blank master for them to cut. Apparently its not only Ernie who has me in the mad scientist category. I just realized that I never went back and played with cams after I had the final intake flow numbers. Ive got more low lift flow than my original estimates and a little less total. More low lift flow has a similar effect as adding duration to the cam and I saw that when I ran the simulation as a little dip in low end power suggesting I could cut the cam duration a bit. Also there was a decent bump in top end power because even though my head is flowing less than the estimated number, the estimated number was at a valve lift I never use. I had plugged in 160 cfm at .500 lift which makes the .435 max cam lift flow about 139 cfm. I actually have 154 at .450 lift, so about 149 at .435 lift or 7% more than the estimated number and again suggesting I might get away with a bit less duration. Steve sent me several cam options or different durations so I need to go back and re-run them in the simulator and see if I can do any better before I lock in and cut the masters. I guess I also need to play with the exhaust flows a bit and see if more less with a shorter duration cam or less flow and a longer duration cam buys me anything
Do all cam grinders still use masters? I had just assumed it was all computer controlled these days, and if it's not can someone explain why?
Most all of them still use masters as far as I know but I'm not sure what the reason is. I know there are CNC cam grinding machines out there and I know one place for sure that has one, but masters still seem to rule the day. I think it has to do with CNCs not really being all that good at curves, they tend to facets. So you CNC the master then hand polish of the facets, then on to the follower machine and out pops a nearly perfect lobe .just a guess though. The masters are big too .6 to 12 diameter so any small errors on the master pretty much disappear on the true size cam.
I know, I know......spring is tuff for me. Here's a picture of the 20 yards of mulch that needs to be put down in the garden and around the fruit trees this weekend so there is room for a new 20 yard pile of nicer mulch for the around the pool, and the front trees and beds next weekend. After that i still have some stocco to finish.......maybe I'll do that next weekend instead of more mulch to mix things up a bit. Then I can work on the car again without fear of bodily harm if Lana catches me Image Unavailable, Please Login
I do need a tractor. Maybe next year.....this year there is a spending freeze in effect at my house due to significant cost over runs in certain unnamed projects........
Hey, I know that scenario! Although at our house it stems from the sudden realization that we have to have the house ready to go on the market in January or February. Shiny Side Up! Bill
The simulator says in might be worht pulling 5 degrees of duration out on the intake cam..... it costs a little top end but adds quite a bit tothe bottom end. Oddly it also say that if I add 4 inches to the intake track length with the shorter duration cams I get to keep all the added bottom end and get the lost top end back....strange.

Chris, you might have a shovel, but,, , , , ,, , do you have "Pilot" experiance with manure.......? Edwardo
Here's something kind of cool....cooler than mulch anyway. I got some real valves. The real intakes look a lot like the test valves...so I guessed pretty good when I made them. Hopefully they flow at least as well as the test valves to. I got a couple exhasut valves that I think should be about right to test with...and they are almost the same size as the stock intakes.

Well.... plenty of time it would seem, but since I am doing all of the work... Yikes!! 2 Bathrooms to renovate, a kitchen to cosmetically fix-up, the whole house needs siding, all the windows need repair, and of course I need to paint. Then there are the dozen or so trees I need to cut down, and the myriad of landscaping that needs to be done! Oh, and I forgot, like most people we have far too much "stuff," and thus I need to move a lot of it to a storage unit, and to make it easier, I might as well make that storage unit in Oak Ridge. I think I need a clone! So, stop complaining about the stuff you need to do and get this damned project finished before we move so you can take me for a ride in it! =) Shiny Side Up! Bill
Wow, found on page 4..... No progress to report at all but now that Ive only got about another month of serious yard work left I took a quick run through the project to-do and to-buy lists. I know Ive done and bought stuff in the past 6-8 months since I last looked at the lists, but it appears that both lists have gotten longer somehow. If I actually stick to the $500/year budget I tell Lana Im sticking to this is going to take another 40 years to finish
$500/ year budget??? I wish i was there when you told her that. I don't think i would have kept a straight face. LOL!!
It's most a negotiated number that we both lie to ourselves about. Lana thinks any money I spend on it is a complete waste and she refers to it as the money disposal. So we have a system. I siphon money off and divert it to the car, then she scolds me but since its never a ton of money we (mostly) forget about it after a few weeks or months if it was a big number. For example she was just explaining to me yesterday how much better the ducati TBs I bought would have looked as a new sofa in the family room since. I mean since the engine is not going to be back together for a year anyway and it wont need TBs until then, why on earth did I think I needed TBs now so they could sit when clearly we could be enjoying a new sofa today? I tell her well of course you can have a sofa knowing full well she has no Idea which sofa she wants and hates to not but sets so she wont buy anything (today) as a result. Now her point is completely valid, but if I dont siphon off the car money a little at a time over a couple years so its hard to keep track of I would never get the funds approved and would find myself divorced the day I tried to spend without approval.
If she keeps giving you flack about the impracticality of your one fulfilling and therapeutic hobby tell her you are buying a 65 foot Cigarette BOAT with twin 1,000 HP engines. Talk about a money pit......................................
That's what I tell her....but to be fair, we don't have any extra money just layinng around waiting to be spent. Quite the opposite in fact so she is right
