After spending 21 months putting together a 400-512 power plant for my 66 440 Coronet I have the car back on the street. The 400-512 is a 11.5 to 1 stroker with TF 270's, Howards Cam solid 275, 276 duration 645 lift, TTI 2 1/8 headers and Pro Systems 1050 Dominator. MSD Digital 6 plus with MSD billet distributor, TCI full manual 727 with transbrake and 4200 9.5 street strip converter and 4.10 rear gear. As you can guess I built this car for both the track and street. I asked a lot of questions at the start of the build, I figured I should share the end result. Once break in on the motor is complete I'll bring to the local track and post the results.

Awesome sound. Well done.
I'm just wondering if an electric water pump has long term reliability on the street.

Great sound! It feels real good to complete a project. I'm seeing light at the end of my own tunnel!

How far are you into the break in?
You might want to keep the idle speed higher early on to ensure the lifters get good oil and polish.

Car looks great, sounds great, and I'm curious what it'll do with those 270's on it. For sure post some timeslips when you get em. What ratio in the rear?

That is super sweet! I'm putting a 66 coronet 500 together and was wondering what the low hemi scoop would look like on that hood, that is wicked!! And I'll be finding one for my car, that's for sure.

Yep, I wonder the same on the electric pump. If i find the correct water pump belt pully I might switch it back. Right now with the 110 amp alt everything is working well.

I have about 5 hours on the motor, break in was un-eventful. Ran a series of four 15 minute 3000 rpm run periods in the garage. Been driving it on county roads at about 50 to 60 mph or about 2800-3200 rpm.

Time to get out and stand on the throttle.
The rings need to be "bedded" in, as it were.
