I am competing in the vintage class again this year with my trusty Lincoln Y block.
I should be on Jay's dyno end of next week..
I hope to win the prize for tallest engine in the competition

Whoa, that thing IS tall! Might have some trouble clearing some low bridges on the way to Lima this year..lol What are those weird looking "Ford" throttle bodies from? I thought they looked like milled pistons at first, but don't ever recall seeing any that had Ford cast in the side.
Besides the obvious intake changes, have you done anything else to it from last year? Good luck in the competition, Royce.
-
The throttle bodies are junk yard items right off a F-150 with a 5.4
Besides the home made EFI intake, I changed the heads to the phase II Joe Craine ported version.
I am counting on Jay (the EFI wizard) to find me some horsepower.
-
Good Luck Royce, we're always rooting for you and the team. And yes, I noticed the throttle bodies right away too.

"1957 Mercury 2dr Wagon "Battle Wagon" drag car Currently engineless" EMC engine is calling.
-
Which One??

Last year's entry which is this year's entry, which will be a real surprise! Joe-JDC

Danger Will Robinson! ;D

I'd still like to pick Ted Eaton's brain a bit about the 660 carbs he used on his Y block EMC entry. The only minimal content blurb in HR said that it really came around when he put on the 4224s.

Ted is at Bonneville this week, so I will reply. On Ted's EMC engine, we tried several intake manifolds, several carburetors, and even a Dominator. Last we tried the new EFI Mummert intake that I made into a tunnel ram by modifying the inside with epoxy into 8 individual runners instead of a dual plane for injectors. After I got the epoxy near what I felt it should be in size and port flow, we tried it with a matched pair of 3310 carbs modified to fit inline with a vacuum tube between the secondary vacuum pots. The 750's did not respond evenly, and we tried different springs, and different jetting. Made so/so power, but not an improvement to the single Dominator on the maximum ported Mummert dual plane intake. Next we installed the 660s inline and were rewarded with an instant improvement in torque and horsepower. We changed the jetting, fresh blue gaskets, etc., and made a couple of pulls to confirm they were actually repeatable. Made 594-596 hp on Ted's dyno in the heat of the day. Changed the carbs to mount sideways so we could change jetting quicker at the EMC, ran a verification pull, and called it good. The carbs are not modified in any way special, just normal tweaking and gasket changes to the non stick, and jetting to get the AFR to make best power. At Lima OH, it repeatedly made 597-603.2 hp, and when he got back home we changed head gaskets, checked things out, reassembled and dyno tested. It still made 597 hp on his dyno. I ported the tunnel ram out further to change the flow from 327 cfm average to 360 cfm average, and it did not increase the power or torque. We did several header tests, and found a new combination that worked. At that point, he felt the 375 cubic inch engine was fairly well sorted out, and further dyno testing would not prove anything more. Joe-JDC
On edit, if I remember correctly, Ted did install metering blocks so jet changes could be accomplished in secondaries on dyno very quickly.

Good luck Royce what diameter is those TBs ?
Im looking for some TBs around 2 inch
-
Heo, these are 65 mm . You would probably need to look at a 4 cyl engine..
-
Yes Royce have found a few 4 cyl around
50-54mm but either real uggly or uneven
boltspacing . I havent put that much energy
in to it just planing for future projects
-
Very cool.
Looking forward to seeing you guys down there.
It appears that my alternate position has gone "live" as of Saturday, and I need to get an entry up and running.
