Could someone run my buddys little combo through the DCR calculator? I have tried to download the program on my computer. For some reason it just doesn't work.
This may get a laugh but its all he has to work with right know. This is a 90's model fuel injected V-6 Dodge Dakota.
Im not sure exactly what figures you need but i'll tell what i know.

V-6
bore size-3.91"
stroke-3.31"
rod length-6.123"
camshaft-intake 250*/ exhaust 264*
intake valve closes at 65*
If you would please run this with a 10:1 compression ratio and 11:1

If you need more let me know. This little truck has run pretty good for a nearly 200,000 mile engine. I gave him the specs on how to make generic style cal-trac bars. Loaned him some slicks. He has ran a best of 9.59 1/8 mile of course.
This has all been done with little to no cash outlay and handouts. A reworked throttle body, cold air intake, 3.73 gears, little to no lightening of the truck. Probably other things that im just not thinking of.
He says he has surprised many full size Dodge and other trucks. Including my own a full size 99Chevy Z71. I tried but i just didn't have enough :D

Do a search for the "Boost Calculator" site and put .0001 in for boost and whatever your local elevation is.

I use both Pat's great site and this one as well as the ROSS Racing Pistons static compression ratio calculator site.

10.0:1 = 8.0 DCR

11.0:1 = 8.78:1 DCR

Thanks!

check my calculator in my sig...

Well i tried to open the file. My computer asked what program i wanted to open the file with and now I don't know which one to open it with. Ive never seen this before.
I tried a couple of programs but it didn't open up.
Anyway my buddy's plans have changed on the cam the one he was going to use is bad. He has another replacement or is getting one im not sure.
Would someone please run this again. All the specs are the same except for the cam.

Cam is intake 240*/exhaust 248*
intake valve closes at 50*

Thanks for the help!

11:1 = 9.65

10:1 = 8.81

Both are aweful high for pump gas . . . you might get away with 10:1 static on pump 93 with aluminum heads and a really efficient combustion chamber.

ICV @ 50* is aweful soon -- this must be a tiny cam. If those are .050" duration figures I need the seat timing numbers . . .

Yes this cam is very small. I told him that it would jack the compression up. He wanted me to check it any. He's got good idea's on reworking engine parts. Its just the fact he is wasting all his time and energy on a v-6 but I guess you'll try anything when you don't have much money.
He has a lot of 360 blocks laying around and ive tried to get him to start with one of those. He says it would just cost to much right know. This is his daily driver truck and he needs to get it on the road quick.

Thanks again Eric!
