I am the other member B3422W5 is talking about. Mine is a pump gas 394 ci that Brett Miller had in Enginemasters. It made peak power at 7300 rpm. I only shift at 6800. It has headers that I built on it and are probably holding it back. It made 662 hp on 91 octane gas. I have been beating on it for over 7 years.
1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...

I though the victors moved the shaft away from the valve so you needed a longer rocker on the valve side? Also a longer valve that further compunds the 59* lifter problem and add on top of that the offset? Pretty impressive it dont just cough the PR out under the intake when you crank it over... There’s another thread going now with the Victors on a Ritter 59* block that they’re turning higher than 7500.

Let’s just say I’d be pretty surprised to learn that the one in this thread is using some off the shelf ootb Harland Sharps.

I’m sure all the info isn’t out there on this dyno Queen yet. Indeed. All the info isnt out there on this motor yet. I shared as much as i felt should be shared about it. As i posted earlier, this motor has over 50 pulls on it already. Very trouble free thus far. It wont remain a “ dyno queen” much longer. It will be for sale and in somebody's car at some point soon

I know there's formulas for this but is 770 hp possible at 7500 rpm with only 378"? I know that much hp is doable at the cu in for sure, I just thought it would be at a higher rpm, have to be some pretty stout volumetric efficiency. 125% @ 350 CFM will get you there

I'd like to see how close that 2.175 Intake valve is to the cylinder wall..

I'd like to see how close that 2.175 Intake valve is to the cylinder wall.. It’s a 3/4 concrete filled block bored to 4.100 so that helps I’m sure. I call BS on pump gas as I see 100 octane and sure it may have come out of a pump but come on now. I honestly hope it works out for them as this may get more Victor heads off the shelves and on some nice race cars.

I'm curious to find out how the bottom end is put together to handle/support that HP. 3/4 fill. He did use 4 bolt splayed caps. I asked him if those two outward splayed bolts had enough meat to attach to for viability. Because on a non magnum block they don't, at least that was my thinking But he said on the Magnum block there is more meat there to make it worthwhile to use them. I learned something. Didnt know the two blocks were different in that spot.

Just talked to Jack..... little more info he doesnt mind me sharing.
Bullet cam. He consulted with Tony at BES regards it. One of Tony’s former guys, John Lohone( sp) now works for Jack and will make the trip down with him. One time Nascar engine builder He said the valves clear with a ton of room. Very well centered in the bore, a big positive for the heads. Said they would clear a stock bore That Holley manifold was indeed only made for W2. He has about 40 hours converting it from oval to square. Tons of work involved there. I had thought they must have offered it in a standard head form at one time, but just W2 Using cyro treated Hughes rockers. Really likes them. Told me he made a plate for the front of the timimg cover where he can pop off the water pump and move cam in not much more than ten minutes. Said the motor is ultra sensitive to cam timing. Currently has it advanced 4 degrees, makes 750 this way but good bit more torque. Couple degrees can make or take 20 horsepower Is likely to move it around down in Charlotte. Said it will break 800 horse spinning it to 8k. Some very trick oiling mods. Had it on Bischoffs dyno recently and Tony told him it had the capability to win the competition. Was very impressed.

I'm curious to find out how the bottom end is put together to handle/support that HP. You and me both. I've had stock block, stock crank early LA 360s north of 500HP at 7500 and know what I had to do to keep it together for a season. And it still wanted to push the crank out of it. Add another 250? How short is the fuse on that? Not busting on the builder. Just sayin', stock parts have there limits. I see they did use an aftermarket crank.

If the results don't match the theory, change the theory.

Crank was destroked a little by Adney Brown down in Detroit. The guy who built the enginemasters 318 i bought and ran. Adney owns Performance crankshaft

Very impressive, I understand about some of the comp. engines mentioned now doing well in other rides, but I kinda think this might be pushing the envelope for longevity with a production block but then again over time it was said a oem block was only good to 500, then 500, then six.
Do you know what crank they are using?
I hope the best in the competition, do you know what some of the "Other" brand entries consist of?
I wonder how many sets of victor heads have sold? For so long it was "we cant get a good cylinder head" and now the price dont seem to be too bad. All 16 entries are listed on the website of the Race engine challenge website

Impressive engine for sure. 800HP wow.
Should stick this on FABO just for the comments.

I stopped making them since there weren't very many SB guys building high dollar engines but it would make sense on a high buck engine like this.
