I ask because I see your builds as very sensible, nice work, what MPH is the 11.03 running? What trans do you run?

Why............you and others could learn a few things from this guy's builds. Heres what I see, the 505 peaks @ 5900 RPM, carries it nicely to 6200 RPM were its only down 7 HP @ 6200 RPM, all from a mild 500 inch hyd roller build, also take a good look at the oil pressure graph, no dropping oil pressure on this one! Like I said nice work!

And FYI, the new blocks have a Chevy style oiling system. That’s the biggest difference.

Starting with better materials, the Rocket Racing Olds blocks are cast in two separate versions; the standard is a proprietary iron alloy, with a Compacted Graphite Iron (CGI) version for those looking to make ridiculous power numbers on a regular basis.
“With all the stuff we have incorporated into this block, I don’t see why we couldn’t push it to 3000-plus horsepower in the regular iron,” John says. “CGI is supposedly 75-percent stronger, given all the same thicknesses and design specs as a grey iron counterpart. If you do the math – 3000 horsepower and add 75-percent – that’s a lot of horsepower.”
The new king in Olds horsepower!

You get a little "touchy" when people start talking about the by product of a good engine build, the time slip LOL. Theres no reason a production block Oldsmobile 455 build has to drop oil pressure at higher RPMs, mine DO NOT. I'm sure the new block is a very nice piece, although its draw back is the max bore of 4.400, buts theres nothing you can do other than change the bore spacing. I think a 4.390 bore with a 4.00 stroke would make a nice combination.

The time slip is more important in many ways than the Dyno to show off real world numbers. Disappointment happens at the rear wheels. Even chassis dynos are not the end all be all. The engine in the car moving the weight is the real world. I wouldn't worry about chopping up the slip and 60 ft. This and that unless you where gonna be serious about racing because for the average guy a good suspension for drag racing will bit be fun on the street so the compromises are what shows up in the time slip along with the hold back of the sled it's on . The most impressive part about his time slip isn't even the time. It's about how his car is probably deadly reliable and not batting an eye doing it.

What gets me is the WEIGHT: APPROX 250 LBS (DEPENDING ON BORE). It does not seen right?
Small block NASCAR block I have, came in as 300 pounds more or less. It does have some massive oil pan rails. Starting to think my trucking company over charged me for weight. Going to have bill weight it.
Mark! What does the bare RR block you have weight?

All out racers, need deep pockets to go with the CGI option. With large internals. Would a DX block with small internals. Beat at the BBO at the 60' line? Equal cars and launches.

Otherwise you’re no different than the rest.

Mine will have 350 Bryant crank 3.385'' stroke and light weight internals. Going with the Batten heads. and intake.Lighting Rods have always given me an edge. 2004r and 3.73 rear. Fast reflexes and intuition also help. This new engine will be take first gear to a new level. Shift into second gear at near 8,000 rpm. Will be a leaning experience!
Take with a gain of salt! Engine Masters season 6 Ep 92. Screaming 8K RPM!! Engine keep's pulling and gaining HP up to 8,000 rpm.

I will let you know soon. I have an RR block here that I'm using for my own build. I also have a customer's 425 block here that I'm currently fitting a girdle on and is getting filled to the water pump holes. I don't think there will be much difference in weight. The girdle and filler add quite a bit.

RPM is subjective. I spin my 355 to 7k with stock rods. What I meant by my statement is that even for the average guy you can probably make great power at lower RPM with plenty of grunt and not even tax the components. When I'm talking RPM I'm talking like Modified production style racing where they spun the engines to 9k + rpm. Which is where my thinking came from as far as comparing cubes VS RPM. Comparing atleast what's been done already in the olds world .
Then there was the episode of engine masters where they made killer power from a 331 Chevy stroker and it went 8k plus RPM. From a longevity stand point the small package to me seems more ideal. When you considers what they do in nascar with the small journal engines and RPM and they sustain such abuse . I know there is no replacement for displacement but the bigger engines just have more mass to knock stuff around. And I know it's nothing new big engines can live it's just a different animal. For me I just like small engines.

These were complete virgin engines laying around a junk yard in Eastern Colorado, I asked him how much he wanted for them and he said 400.00 a piece, at that point I had no interest.

I am sure this Rocket block is far better of a foundation than I will ever have to start with. My question would be does anyone have info on how fast someone has gone in the 1/4 with a rocket racing engine.? Is there a low 8 mid 7 second 1/4 mile. Fillerbrown put on a show at Wichita in 2019 He took the top rocket with a 482 BBO using a 455 factory block. I think he went 9.03 and he was racing rocket block cars . He is using a Diesel block now.

Is that with a symmetrical port head? I had these guys come into my shop with what they called a Buick for a dyno test, it made over 1100 HP and the guy said "what do you think about that Buick", he knew I raced a Buick stocker, I said laughing, I don't see one Buick part on it.................

Not really a Chevy guy telling us what doesn't impress him! This is a Rocket Racing Block thread . Not a Chevy thread. Vortec is always talking about other people's stuff. He can't represent a rocket block or a racing Oldsmobile factory engine and Oldsmobile car of his own that he races.

Wr1970 I won't tell who it is because the cult my randomly text me in the middle of night because I mentioned a conflict of interest. But I will say it was posted publicly making those runs.
