Bret, do you see a problem with doing it that way?

Re: to stroke or not to stroke
What about elevation? Say it is Summer in Vegas and he has it turned down with the box. Now he wants to go to a place that the elevation is a good 1000 feet lower, or more. Is there enough adjustment with the box, or will he be in trouble? Or is elevation even that big of a deal with DCR?

Re: to stroke or not to stroke
DA is a factor with DCR yes... the denser the air the lower the DCR should be, so yeah elevation plays into that. The Box has like 9degs if I remember right, if you can't take enough out with that you are doing something wrong.

I would imagine ya could dream up a situation that it wouldn't work but ya would have to do a LOT of thinking.
Well I reckon I will just have to think up another "trick" to get an edge on these boys.Reckon I could put ours on fuel and go for it.With the **** ya could do either fuel or pump gas.

Re: to stroke or not to stroke
Didn't even think about elevation that much... There is Mt. Charleston with lots of twisties that I am anxious to eat up when I put ole betsy back together. So that would be like a 7k ft increase in elevation. Very fun driving!
Emailed Lloyd to see if he would hook me up with the IVC close of a few cam options... I'm glad I posted this in here, you guys are very helpfull! THANKS! Now hopefully in time I will end up with a combination that works very well together

Re: to stroke or not to stroke
I can help you with the DCR but he probably is not going to give out the IVC of the cams.....
If there is something you want to shoot for just tell him and we can set the DCR to that level for you as long as you give me all the mesurements for the Compression Ratio.

DCR is what the engine actually SEES when running and it's got to do with the IVC point. The higher the static the more the DCR in the same engine combo.

Re: to stroke or not to stroke
well, im going to shoot for about 8.6-8.9... dont know what dish pistons i will need yet... right now they have me lined up for -5cc but not a big deal to change. I figure i will ship my heads to lloyd and let yall fix me up. that way when i get my goodies back I will know more about the cam profile.

Re: to stroke or not to stroke
Not a problem man...
When you get the cam you could figure IVC with a degree wheel without much problem. I try to shoot for 8.3 DCR on Lloyds packages to make them fool proof and have lots of TQ and HP. Going farther sometimes happens with some customers, but for the most part they are designed for this range just so they are safe.

Re: to stroke or not to stroke
OK, final delimma... if i go with a 355, i could put a few more bucks with the money i would save... and get a good set of heads that Lloyd could hog out. have a killer set of heads, and probably the same power... or a tid bit more. Am I wrong?
