TW -
Thanks for the pics of the Bronco. I'm thinking it will be a pretty nice paint job when done.
As for the 418, let us know when and where you'll be listing it for sale. I know some folks who may be interested.
As for the undersized bushings for the small ends of the rods, is that overkill? Are you using OEM (capscrew Lemans?) or aftermarket rods? If OEM, have they already been re-sized or were they a mismatched set? If not, was the center to center length off enough to make a difference? Obviously, when you're working with a zero deck, you have less margin for error, but this is a new step for me and I've built a few motors with zero or near zero deck.
Thanks

Scott,
The rods were not all from same engine. After resizing the large end and adding the ARP bolts and having the small end a bit too loose for pin we had to order new bushings anyway. Same cost for the bushings for std or undersize and it was a simple step to make them all the perfect length.
(just so its clear, the pin size will be standard)
It was just one of those just because we could and all about precision machine work.
In the past I had one of the "Pro's" who is very well known do machine work for me which I paid dearly for and pretty much all the machine work was a joke. There was very little we did not have to re-do. The deck heights were all over the map, the final compression was off well over a full point.
The decks were not at all square, pistons were supposed to be @ zero deck but were not close. His comment: "There are other things that will make more of a difference". When I purchased said parts I was told it was perfect, having paid the full cost for good machine work and finding it all a joke I decided on this engine to make it right the first time!
As most know it costs a BUNCH more for the step up in machine work vs the run of the mill get-er-done.
I still have no clue why I started this build as funds are very tight right now, Just to do one last FE maybe . . . . . Hard to explain really. I am not one to cut corners on whatever I do.
This 418 will be making it right without spending BIG $$ with basic parts.
At this HP level (hoping for 475hp)
Compression will be 9.86 with a Dynamic of 8.06
In other words no billet crank, no big $$ rods, no fancy roller rockers etc
Of course they can be added along with a larger bumpstick if someone so desires. (sorry for the long winded reply)
As of now the engine is for sale contact me by pm or email.
In my typical fashion the engine will also look nice with all plated bolts, base clear coat paint etc.
Carb to pan setup, It will be setup with a front sump pan, windage tray, good oil pump, bottom end as described.
Custom Flat tappet Hydraulic cam with non-adj rockers for ease of maintenance.
BBM Heads that flow 296 @ .600 Intake with very good low lift numbers
.220 @ .600 Exh
New QF 780 Carb, New Perf RPM Intake with a bit of "tweaking"
Very nice set of Cobra Jet ALuminum Valve Covers (original not repo)
I will drop in a vehicle to get a RWHP~TQ number and to make sure no leaks or issue's. (none expected)
I would estimate a good 100 HP loss as I have found in the past
So it should make 375 RWHP or close. Soon will find out I guess.
Not aware of a good engine dyno place close . .
Seeing as though so many Older Ford~Mercury vehicles are in the 4000lb range that is what the cam was made for. ALso a typical 3.50 rear gearing etc
And yes hoping the Bronco paint job turns out nice! Have not painted anything other than a bumper or fender since 2010.
