the ms2 extra or ms3 has native support for the gm 24x wheel. as for bolting the 4l60 to the 307 its not gonna happen without an older torque converter

no 4 bbl intake, no 2 bbl carb. the fuel supply also will be troublesome

i am going to be swapping out my 347 for a stroked windsor, and need to seat the rings immediately after cam breakin. i generally do this with wot applications to medium rpms and decelerate to idle and repeat many times while increasing rpms about 100 or so till i hit redline.

the power curve of ...

i took a closer look at your msq and log. accell enrich is all wrong for that size injector. try settings something like this
tpsdot threshhold of about 25-30
turn off map dot completely for initial dial in and ve tuning. (slider all the way to the right)
make a tps chart that looks something like ...

did you happen to buy the "summit" 42# injectors, if so they are very touchy to voltage for opening times. i did some semi-accurate testing on them which helped me alot for stabilizing afr. by semi i mean a 60cc syringe for capturing fuel and a battery charger and headlights for varying voltage with ...

i followed the instructions for cal dt
i used a 45ml syringe attacted to the injector with a hose

did the flow tests and came up with

11.9v
4ms 26ml
6ms 40.5ml

13.3v
3ms 19.5ml
6ms 42ml

14.9v
3ms 21ml
5.5ms 39.5ml

i came up with
11.9v .62ms dead time
13.3 .4ms dead time
14.9v .162 dead time

im having trouble finding the right opening time for my injectors(summit racing 42#injectors, 12.8 ohm, they appear to be made by lucas). doing the cahnge from 2 to 4 squirts isn't working at idle because the injectors never fully open on 4 squirts. i have an idle pw around 1.8 - 2.2 ms and cruise 1 ...

i was building a ms for a friend who was going to buy a msd unit later and use direct coil control till then. while bench testing it with a real coil and setting it up, i thought why would the phase change with msd?

the phase changes out of the cpu-igbt-coil is what confused the living heck out of ...

under the msd ignition setup page it states to use the igbt driver, mod th ini for 25ms dwell and set spark output to normal. i understand the reason for the ini mod it is to more or less simulate real points for they work on a fixed degree not a fixed time. the high current driver i really wouldnt ...
