What is my correct compression ratio?

3.73 rear end gears, AODE stock(ouch!) with HD2 shift kit. And Forced induction are in plans for the future, I am thinking vortech at about 8psi(engine block is stock, don't want to push it too far.)

So what intake would be a better match up adder?

I too use the stock aode I have a tfs street til next week thats an ouch! I run 7.80s as of right now with mic radials. No tune, no caled maf!
I have a pa vlv body but those shift kits shift harder than my vlvbody! With new rubber intake and maf hope to be dropping a couple tenths! Then tune and a 250shot on a progressor! Should dig up som mid to low 6s.

The reason I ask is that I went and ran the car at the strip in september and my results were less than impressive. My 60ft times were were horrible due no traction (like 2.6 sec!!!) and I ended up running 13.7@110mph. the weather was perfect and in Indiana its only like 800ft above sea level. This leads me to believe for one I obviously need some better tires, but also perhaps my motor is setup incorrectly. (It runs fine, car is just still too slow lol)

My current setup is eagle 347 stroker kit, AFR 185 heads, trickflow track heat intake, 75mm TB and like an 80 or 85mm MAF, long tubes and 2.5 in. exhaust. It has the cam Linked above with a 3200 flash speed stall. Also has stock pcm with a chip from ***** lynch at dirtydirtyracing.com Does this combo of parts sound like it should work ok with eachother? I have been told intake is too small, but I also worry that the cam is too radical for the low amount of compression.
your trap speed seems a little low, the 185 head should be fine, I run the same head and have 120+ trap speed, the auto tranny maybe robbing some, but more so I'd focus on hooking it up, how's the suspension set up??

Yea, I thought my trap speed seemed a tad low as well. The suspension is totally stock at this moment. Also has just regular street tires at the moment also. My plans for the future are:
1:Some drag radials or slicks.
2rag racing springs, summit sells some from eibach and from steeda that are supposed to be ok for street use as well. I have heard many negative things about Eibach though. Probably will go with Steeda.
3:Forced Induction. I'm thinking Vortech Centrifiguel kit at around 8psi. This may change though, depending on what I come up with from further research.

I would really like to do something different with the trans too, just don't know what yet.... 6 speed would be nice.....

Also I forgot to mention, the car is not a daily driver. Its main purpose is going to be the drag strip with very occasional street use.
