Well I still don't know which way I am going to run this engine. I have
a stock GM PCM I could use along with wire harness I have modified. I also
have a Megasquirt II and EDIS 8 ignition setup that I have now started this
engine with on the engine stand. I would like to compare how this 5.3L
engine does against the 6.0L engine I had a while back. The 6.0L used the
same Megasquirt & Ignition setup, along with my current TH400 trans and stock
torque converter. I ran 13.95 in the 1/4 mile with the 6.0L. I'd
like to do the best comparison between the two as possible.
I then would like to put the stock PCM and harness on the engine and install
the 4L60E I have so I can drive my pickup more with the benefits of overdrive.
So I'll probably end up at first putting the Megasquirt control in first, with
the TH400, then later put the stock PCM and harness in and swap out
transmissions.
