Hey guys I would just like to point out "I" did NOT Provide Ion's tuning.

Yes my Tuning is for OBD-II but I also have been swaping back and forth with OBD-I. I can not share the file as Ed Write has been helping us with the "No Shift" fix(which works BTW )

My best N/A to date is a 11.85@114 with a 1.65 60ft spinning E.T. Streets. Weather was good but not quite Texas weather.

After that run I hit the Scales at 3,84x.

I have not had the ***** to try for the Stock shut off but on BOTH OBD-I and II i hit the MSD 7,000 chip before factory shut down. I hear you WILL know when you hit it. the car shuts off and you have to do a Key OFF restart

Good luck all!

how jacked up where these heads to begin with?

sheesh, if you gained 40rwhp AFTER phil ported them-

that means you were pulling 340rwhp through the ARE's and a big cam like that.

wow, that sucks. a lot.

Torque seems real low, but maybe the heads were too hogged out in certain areas. Its tough having someone rework somebody elses portwork. Good hp though.

see this is my problem i cant decide whether to go with the 847 or the EX 233/239 on a 110. the 847 make good power. but i will be runing a stock bottom end. and i dont want to spin it over 6500 after the cam.

which one do you guys think i should try. either one will be on ported heads and LTs.

not trying to steal your post.

Your exactly correct on that, my buddies 396 hit it when he first took it down the track. Since has gone DFI, but scary to loose everything at ~120 in the 1/4. Im thinking of putting a 6800 pill in mine right now just to be "safe" (anyone have one lying around ). Once the heads get ported not sure what i will do. Decisions....
