Looks like fun - i am about the same spot putting mine together at the moment - pistons are in but heads arent on as I ended up needing custom gaskets made up and they just arrived.

What pistons are we looking at there? What is up with the really long main studs?

Possible, but not one I have seen before. They look like smaller diameter extensions like the one you would need for the oil pickup.. it is definitely not a stud girdle. Will be interesting to see

Yup yup. Windage tray indeed per suggestion from one of the fellas on here.   It's on there as of now, but due to the rotation I had to flip it around backwards, cut one end off and tig it to the other side. Fits good now, with about 3/16 to the rod bolts at the closest point.

can't remember what the pistons are cause its been a minute since we ordered all that.. Will find out tho.     

Hopefully I don't blow up all of this stuff!

I lied, the pistons are Probe not Ross. 10676-030    And that 383 looks pretty sweet! I'm considering putting March stuff on mine too, and maybe convert it to serpentine.    Hard to know where to draw the line..

The things you learn.

They were nice enough to refund my money even though they had already started on the grind which is cool.    


Just wondering what cam you finally decided to go with and what specs.

I've heard bad things about the eagle crankshafts snapping near the rear maing journal :S. That is what I have seen online about the mopar 408 stroker cranks but I've also heard that SCAT makes a much stronger piece in that regard. I don't know if the same holds true for a ford. Either way stroker motors are where its at. And an 83 motor with a one piece rear main? I thought that the 86 motor was the first for that if not enlighten me.

The switch on rear main seal styles (for the 351w) happened in '82-83.

Ill throw in my 2 cents Pete. Maybe it was 86 when chebby switched to the new style crankshaft that wouldn't bolt up to the flywheel we are using in the skylark. Its been a while since I built my ford haha. Thanks Tim.

file-fittin some rings..



had to I cut one end off the windage tray and re-weld it onto the opposite side to spin it around for the reverse rotation



some were asking about the cam specs.. It was per recommendation from Comp



















Got it all put back together this weekend and took that pic while running it for 30 mins on Comp break-in oil before swapping out to real oil and reinstalling the inner valave springs.   

Sorry for all the uploads but I'm excited about this sucker!

Is the brazed port in the exhaust riser for a O2 sensor?

Looks pretty good though. It would scare the heck out of me as if it cracks you are going to cause some trouble, but I guess if you didnt crack it welding it and cooling it down you should be alright.

That boat is looking pretty sweet.. I am jealous I still have to put on my intake manifold and paint the block tonight.     

I have used that same number probe piston a few times and they look different each time I order them. My last set cracked right around the dish pocket, apparently I wasnt the only one that had that problem because it looks like on your set they changed from a relatively sharp transition to a very generous radius in that spot. I like to see the continous improvement from them.. just wish they did it a little sooner!

When do you hit the water? It should be very interesting to see how that thing runs out.

Load it up and bring it down to florida to the SJRR in late march and I will swap rides with ya.

I made an 02 adapter a few years ago for pcm manifolds but ended up using a different set of manifolds on my boat. I'll try to find a photo of it tonight but there is one on the site somewhere. It was an experiment so it's yours if you want it, I'd just like to see someone put it to use.

edit: found the picture, the 02 sensor is not included, just the adapter
