Another piece of the bottom end puzzle! Main studs!!!! Waiting on the side cap bolts now.. should be here between now and monday night .


Very exciting

Did you have to get two sets or were you able to source the correct amount for the v10?

I bought the extra mains worth of arp straight from arp. Those are in the engine already. They made the main bores rounder and more in spec. Was shocked since I was expecting them to distort them more, making them more egged.

Correction... logistics have surprised me once again. Arp side bolts have arrived. I am impressed... the studs were scheduled for tomorrow and the side bolts were for Monday. And here they both are. Ups guy has been running nitromethane.

Nothing exciting this post as I spent yesterday being Paul Bunyan cutting down a 90 ft Norway maple with a hollow base in my front yard. But today I power washed and scrubbed red cars inner fender liners. Scuffed Them up and sprayed them satin black. Nice and pretty. When I get the car back next century I intend to do the rears as well.

I also tried spraying the spare tail light bezels gloss black but they turned out horrible. So I will need to resand and finish those. Have my new 3rd brake light and rear bumper reflectors ready to in as well. Oh and my new ebay tires came in. 265/35/18 lexani lxuhp-207s. 187 shipped to my door. Now I'm eyeballing up a set of the 285/35/18s for the rear. praying this thing get sprayed asap so I can just slam it all together and start cruising.

Well no progress with the car itself.. surprise!
Decided to take action on another front. Pulled the crank, added the main studs, re-measured the bores.. this is a point of contention. With the studs the bores were significantly rounder, only for whatever reason the oil clearance was larger to the median journal size we measured to originally. Makes NO sense.. according to ford they are in to out of spec. According to the rule of thumb of .001" clearance per every inch of bore. They're in spec. So they measured .0018-.0035. The more I check in spots on bearings the crazier I got. I have decided as a machinist in the centerless world, I am way to anal to be building engines. The bearing tolerances are hot garbage.. Anyway rant over. I decided I could be at this nit picking for an eternity so I would just send it.

Then went on to install the crank, measure crank end play. Was .007" excellent. Spins smooth with all if the ultraslick on the bearings. Next I torqued all of the rod bearing bolts. Measured the oil clearances.

All were in spec so I went to work installing pistons rings, while doing this i realized i had installed some rods backwards to the pistons... so i quickly rectified that. Wiped the bores out. Oiled them down and broke out the compressor.

This 3.552 bore taper compressor was by far the easiest part of the install. The pistons went in with little to no effort.



Lubed the rod caps torqued to 22 lb ft +90° rinse and repeat 9 more times and voila.

Making moves, son! Turns over smoothly
