This is sort of a plain vanilla build to you guys, but it turned out well so I thought I would share. It is a 428 built to look a little old school like a 406. Ford Tripower setup and Comp 282S cam. I thought the tripower would hold it back, but I think 415 BHP & 500 TQ is pretty stout! I built this engine to sell, since the project I collected the parts for is gone, but now I'm not so sure.

I dig it! Can we get some more info about the components? What heads, valve sizes, porting, etc?

It is a .060 over PI block, TRW flat tops, about 9.8:1 CR (the deck came out around .030 which is not what I wanted but I didn't have it decked to correct it). The heads are C8AE-H with CJ valves and a good valve job but no other performance work (except drilled for 16 bolt manifolds). The Tripower came to me as a box of parts and I put a kit in the carbs and installed the original/stock jets and PV and it worked out fine. The port match looked pretty good to me so I left it alone. I am running 1/2" phenolic spacers under the carbs to get clearance to the Mallory Unilite with the stock air cleaner. The cam is advanced about 1-1/2 degrees and we ran 33-1/2 degrees total advance.
What am I forgetting..?? I think that's it.

Wow, those are great torque numbers! The intake is definitely hurting the engine on the top end, but what a stump puller...
-
Jay - we did break-in on just the center carb. After cam break-in, we did some light pulls to seat the rings, and on just the 2-bbl carb it flashed over 400 lb.-ft. of torque as soon as we loaded it. We both just looked at each other; we knew this thing was going to put up some good torque numbers! ;D

That torque curve is nearly identical to my 468s........I'm thinking those smaller ports in C8AE-H have higher velocity making more low and mid range power.
I have a set of those on a mystery engine I have.........maybe worth a try sometime.
That engine looks great, by the way.

Back in the 80s the rumour was that mopar 440 six
pack had bigger end carbs and gave some more
topend.I dont know if its true but thats what i heard
