Didn't see this until today. Very nice stuff, lot of patience there.


I will say I have never had an engine give me so many issues. I haven't included any of that though, thought I would spare everyone. My patience has worn exceedingly thin with this thing...

Forgot a shot of the rockers and the whole engine:

Couple of last minute mockup things. I decided to try a different approach to my coolant drain setup. I am going to tie both the block drains into a tee with the radiator, so I can drain it all at once and from a convenient place. I also picked up some 3/8" valve cover spacers so I can clear my custom rocker stands without modifying the baffles. Since everything has been milled, I needed to elongate a few of the holes so the spacers and valve covers would line up.

Very nice work, Jared. Something tells me you've put a little thought into this build?  ;D
12.5:1 compression is pretty stout. What does your dynamic compression work out to? I assume you want it to work on pump gas while on the street? Any thoughts of doing Drag Week if it comes around to your area?

I'll be curious, after some street miles, if you have any seeping issues on the oil pan, since you didn't use a gasket. Was your thinking to eliminate the pan deformation that occurs when using the gasket?

Thanks Doug.

I would've liked a little more compression. I was hoping this time around to bump it a full point from last time. It was 12.0:1 before, did a little more milling this time, but not enough to reach 13:1. I had to check on the dynamic again because I forgot. It came out to 8.99:1. I was not concerned this time about pump gas, but I *might* get by if I am very careful with a few tweaks and don't flog it. I think I have settled on a 4.71 gear for now. I have a 4.86, but might be a wisker too much. I would've loved to do Drag Week '17 with it, which is why I'm in this boat right now. In '17, the tracks couldn't have been any closer for me. It was ideal. I live about halfway between Byron and Cordova. About 40-45 mins. to Byron and 1 hr to Cordova. Easy drive to the track when I want to race. I see the list for the 2020 tracks, and am debating. I should have the car together by then. I couldn't JUST build a new engine......I had to upgrade everything front to rear.....may add that to my build thread.

I haven't seen any seepage yet on the pan rail or timing cover. I have a good amount of faith in it. I use Motorcraft TA-31 exclusively. I haven't found anything that the stuff won't seal through. I first started using it at the dealership and saw how well it worked, so I started using it at home on my own junk. All late model engines are assembled with just sealer. Only gaskets are for intake and valve covers. I also didn't want to stack 2-3 cork gaskets in there and worry about cross member clearance and also pickup depth. The pickup depth checked fine the way it is currently.
