Give me a month or two and I will report on the over all good/bad on the on3 351w kit.  Just for the record I have already upgraded couple of Tclamps, Vclamps, and header bolts to grade 8.  I bought some remflex header gaskets.  The stuff that on3 sends is cheap and will burn out.  As a man with years of turbo experience, you cant have exhaust leaks before the turbo....

Update

Got the engine/tranny spacer for sbf/c4/small bell 157 tooth, autolite 24, 5.8 emblems(to keep me honest)

Hopefully tranny in on Friday or Saturday.

I have Friday July 13 off.  Going to work on the turbo stuff then....I hope.

The ebay spacer plate was for the 164 tooth flexplate(which I didnt have) and the bigger bellhousing for the C4(which I do have).  So I ordered the correct flexplate sense the one I had was the 157 tooth version. 
Stupid roadblocks....grrh.

Got a couple of roadblocks completed today....the intercooler and piping can be installed without removing the front bumper and stuff.  Got the headers mock on there.  Need to finish that up so fuel lines and such and be installed.

Also got the correct C4 bellhousing, 164tooth flex plate, 2500 big torque converter, and spacer.  Not going with the tiny Mustang II stuff.  It will be for sale shortly.

Tranny is in.  Using the 164tooth bellhousing is going to make it tight for the 3.5" downpipe....might be using a hammer....

Hey Jim....

Im hoping I dont have to use one that much....the underside of my car is pretty....no rust or slim.  Oh well the relentless pursuit of power...  :)

I have some time tomorrow to work on her.  I will hope fully have the rest of the turbo kit installed.  Then fuel lines, tranny lines, and the fuel injector harness....batch fire style.

Got the header on.  Also finish the last of the passenger compartment wiring.  PiMP is all mounted with cable read for a computer.  I believe I got the alternator problem work out.  That down pipe has me worried.

I know guys make it work all the time with 3.5 inch. I don't have any experience fitting one myself.

Got the headers done.  Intercooler piping done.  Back to my buddy shop for fuel lines and throttle cable.
Now with the tranny and engine properly mounted.  The hood hits.  I can mill 1/4-1/3" off the upper and couple of washers on the hood should work great. 

Oddly lots of the 86 2.3t wiring works under the hood.  Sensors and such.

Getting closer.  I removed Tue front sway bar for easy of access.

Not a project for the faint heart!

Calling it quits for this year.  So back to the garage with the 351 and most of the turbo kit.  I had to remove the C4 again.  I cannot get the 3.5" downpipe between the 164tooth bellhousing and firewall.  So Im going to switch that again....grrh.  As time allows I will work on it abit.  I will get back on it in April, weather depending.

Would it be possible to make the pie more oval at that tight spot. Not flattened out, just reshaped. I have also seen oval pipe for sale for flatter exhausts. Still has the same volume inside, just a different shape.
