I will continue this thread since I had the same problem.

First I had a Start condition but engine running very very bad , not drivable. Check engine light is on.  Try to pull the code and doesnt work .

I did open the pcm right away to find the circuit pin 46 sigrtn was fries. I fixed the pcm but now before install back the pcm I probe the pin 46 with my dvom and when I push the clutch and turn the key , I have 9-10V .

Is normal since the pcm is not plugged or there is a problem in the wiring . Car is a 93 manual GT with a A3M , Wiring is original .

Combo. 9.48 deck, 1133 mls head gasket, Canfield 450 192cc 64cc milled .030, Crane  gold 1.6 rockers and morel link bar lifters hyd roller.



         Thanks

I had one that came on this wagon I picked up, sold it for $250, and then paid $90 to ship it to north Dakota. Put it up on corral someone will buy it.

Pulled the timing chain cover off a 92 351 and double roller.

It looks like those E5AE heads have really large combustion chambers,after looking at those charts I should have put some E7 heads on the 70 302 I have to drop the compression some since it has around 9.5 and is almost too much for todays regular grade gas.

yeah, i slid across 3 lanes doing something similar on an on ramp.  gave it a little left steering wheel, and a lot of throttle...slip n slide across the interstate.

fortunately there was no traffic that day, but the dividing wall was coming at me FAST. 

PM David Claflin and/or Mr Blue. This sounds like something they'd use.

Sounds like a very robust short block that is going to have some serious power put to it.

   That's too funny!

I'd go with the cubes simply because it's easier to swap the heads, intake, and cam then pull the motor and have a 408 built down the road.  Should equate to less down time as well.  The 3.55 gear should be fine with the larger cubes too.   Also, those heads aren't all that tiny for a low rpm driver 408.  Ideally, you'd want bigger.  But, they can work fine and make good power for your application since you already have them.

How you drive it may be a problem!  You don't want to end up in a ditch or a wall.  Each build could potentially make way more than enough power to get you into trouble if you over drive it.  The back end can swing out QUICK and send you in a direction you never intended.  I've had a close call up a freeway onramp going WOT and hitting an unexpected bump on dry pavement with a much smaller motor.

The transmission may or may not survive.  I might if you have a regular street tire on the back and don't get stupid power shifting it.
