Sweet ride! Awesome job you're doing!
Just made 510rwhp 7000rpm, and 411ft lbs about 5500rpm on dyno! It has felt much stronger from last year but never figured I picked up 93hp! Guess I need a new driver at the track, new best is 11.42 in the heat of the summer at NMRA Milan, MI.
Different dyno and great air today, but still 510hp on NA 331! As comparison, also Dynoed 94 f150 5.0, auto 3.08 rear gear in drive made 168.8rwhp at about 4000rpm and 267ftlbs torque.

dyno sheet and video. Look at that torque curve!!!! Not giving much torque up top! I need to get this thing at the track ASAP!

Damn, that's cool.
Is your engine zero balanced? 7500 RPM and 500+ to the tire on a stock block would make my butt pucker!

28oz balanced... The whole short block is Cryro treated before I assembled it maybe that will by me time/hp. Although I see a lot of guys on HC5.0 making big power on stock blocks running for years. If it brakes I will build another with a big bore 8.2" deck Dart 347".
The first was actually 475hp with the E brake on LOL
Another of the actual 510 pull with the E brake off

oh maybe they are...all I know they are a pain to put on and do not get removed with out pulling engine since I had a skid plate welded on the bottom. Also only found that the the stainless ARP with 3/8 12 pt head work the best to install, and even that is box wrench only. I always start the outer 2 then set the engine in car which allows headers to swing to add clearence, then install the other bolts.
Yah pretty sure they are 1 3/4- 1 7/8!

Sweet fox and awesome thread....thanks for sharing.
Are you running any kind of pan girdle on the motor or is the Thunderbird block any different from the stock mustang 5.0 block that would have been in that car. I see balancing makes a big difference for high rpm but just wondered what else was done to safely get to 7500 rpm.
....and what wrong with the color? That dark green is the best..

All late model 5.0 roller blocks are exactly the same, regardless of what car it came out of.

NikwoaC - thanks for the info and I loved your engine build thread.

Thanks, man!
ARP main studs, to run 7500+ rpm these are really light pistons, pins. I think a forged crank and rods are a must. Alum flywheel and good balancer, much more rpm and should go to 0 balance. I think the valve train is more critical, solid roller requires fair amount of spring pressure, 3/8 push rods a must, I like the shaft rockers as I feel you can get more accurate lift at each valve, there are also some geometry advantages, I prefer titanium retainers, lash caps to add surface area to valve tip. A meticulous machine shop that knows how to balance and bore and hone a block, even then I still chamfered the bottom of block to remove sharp edges that could create a crack.
yes I do not know the history of the car but that is the block that it came with, when I broke down the code on the block.
Yeah Nik get that baby tuned!
