I believe the Ford RY45 is really just an aluminum NASCAR spec FR9. Jay might have insight from his friends at Roush on if there are power differences with an equal spec build.
Not sure you can compare the RY45 at least the dirt late model version to the FR9, just due to the RY is 436 CID. Don't they make another version of the RY45 more similar to a cup engine that I'm aware of, but certainly possible.
We have 2 of them and they make 906 and 908 and that is on a different dyno then Andy Durham's. On a side note: we dyno'ed it with 1200 laps (to get a number since it wasn't Durhams dyno) and then freshened it and redyno'ed it and it was only down 8HP before the freshen!
So if the block needed to take a set, it wasn't worth much.

13 pages of name calling and nothing learned.
Go get a Snickers.
Even that won't help. You have people who are professional argument makers. You can post your real world experience, backed up by professional people no less that Larry Meaux and Darin Morgan and they still want to tell you how stupid you are because so and so runs his car on a dirt bull ring with a stupid weight limit blah blah blah. Or how an inline 4 can be compared to a V-8 that has had its architecture blown out beyond what any engineer ever had in mind when designing it.
I mean really...can any thinking, intelligent man not see the folly in such thinking? Let's take a liter 4 cylinder, and increase its bore, stroke and RPM increased in an equal amount to what the standard American V-8 has been and THEN tell me how good the aluminum is.
Not one of us has said aluminum doesn't have a place in engine blocks. If you are under 1000 HP and N/A and if your stupid rules don't allow flyweight shit the cast iron will beat it every time.
I had a customer back in 1998 with a dragster. I begged him not to buy an aluminum block for his car. He figured weight was better than HP. It wasn't. Since it was a rear engine car, he had to add weight to the car to get it to hook and he gave up power.
He stepped on his own dick. The car never performed like he thought it would, but did exactly what I told him it would. A couple seasons later he parked the car.
I would never build a 12" deck height 5.100" bore engine out of cast. The block alone would weigh probably 7-800lbs. Maybe your issues were ring seal. Fix that don't blame the alloy.
What's funny is even the LS engine. I have some the same 408 combo in iron and aluminum and they make the same power NA/Boost within 1-2% I just don't see the huge loss you do. I guess I'm the only one.
Ok, are we talking about a 12 inch deck engine or are we talking about a Speedmaster SBC based engine? Yes it makes a difference. I've had my hands on enough aluminum shit with many names on it. Not one ever had a straight, round bore after a few heat cycles. The bores in the block go out of round. Then it puts the sleeves OOR. We were buying over/under sized sleeves, boring the block, fitting the sleeves and them boring and honing back to size. Didn't matter.
Again, for those who can't read or haven't followed the tread...aluminum has its place. But for the OP I'd say I doubt it's worth it.
I can't imagine how many more different combos we can bring up to screw up the thread. It's about the junk assed Speedmaster SBC block. Nothing exotic.

What type of tooling did you make your bores round with? So just because you have built a bunch of junk, you will slam anyone else that inquires to use an aluminum block? What if this block happens to be great?
Foundry and machining skills can be the same or better overseas than here in the USSA. Who knows the process? All I am saying is if he wants to use it, why not? I would rather out the extra money into valvetrain parts. It's his money
I had a guy tell me to build high 600" engine for a show only car. He wanted aluminum block, asked if we could polish it, polished BDS blower, polished heads, polished and engraved valve covers, gold anodized carbs. And didn't care what was in the rest of it for parts. It could have been a 427 tall deck for all he cared. He just wanted the look.
Do you belittle him and take away his dream?

Re: Speedmaster aluminum block
Take your sad butt hurt somewhere else. I don't care about where something is made. You just go on some rant for nothing. Did you read the thread? I doubt it. Never seen the Speedmaster block. Nor do I care to. It's just another product for a need that isn't there.Headguy wrote: ↑Wed Jul 11, 2018 4:07 amSo you know these are junk how? Have you used them?

Re: Speedmaster aluminum block
That's how most threads seem to end up. Seems we have a bunch of immature, scared little boys that like to talk shit behind anonymous screen names.
Be an adult. Own what you post. Put a name to it.
Or is that too much adulting for one day for all the little boys at speedtalk?

Re: Speedmaster aluminum block
The finger is healing, but not as quickly as I need it to.
Went from this:
To this:
Have it in a splint as of right now, start physical therapy next week. Hard to work with 1.5 hands, but I'm getting stuff done. Just knocked out a 402 9.200" SBF short block last weekend and got it shipped. Took a lot longer than it should have though. Appreciate the concern, thanks for asking!

Re: Speedmaster aluminum block
Don't know the performance difference between the two blocks, but the first version of the RY45 was basically an aluminum FR9. They had a max bore of 4.150 if I remember correctly. They weren't a Siamese bore (just like the FR9) so you couldn't take advantage of the 4.5 bore space. The newer versions are siamese.hoffman900 wrote: ↑Tue Jul 10, 2018 7:48 pm

Re: Speedmaster aluminum block
IIRC, David Reher said they lose about 40 horses on their Aluminum block pro-stock stuff. Also said they run a different cam in those deals to spin them a little more to make up the deficit.
Considering those are around 1300-1400 horsepower 10,000+ rpm combinations.. seems like pissing into the wind to pointlessly argue about a lower power application speedmaster block being down on power just because it's made out of aluminum. But.. some guys like to constantly pick turds out of gnats asses so here we are again.
Wasn't born yesterday either and I'd take my 357 cast aluminum World 18 bolt SBF block over any OEM cast block any day. Even if it's down 20 horse.. who gives a gnats ass when weight reduction negates the loss and helps me turn faster.

Re: Speedmaster aluminum block
That about sums it up. Even Darin Morgan says the alloy sets after some run time where at that point it picks up 20 hp. At this point the gains offset losses. My buddy says he needs 65 hp more out of cast to get the same et on 125lb weight difference. He figured door car would need more hp.The speedmaster block actually looks decent in pic from grant.

Re: Speedmaster aluminum block
Not after "some" run time.........after 2-3 rebuilds. How often do you rebuild? Once a year? So you have to wait 2-3 years to possibly see a difference?Steve.k wrote: ↑Wed Jul 11, 2018 8:35 amThat about sums it up.

Don't forget Larry Meaux's data: on a Pro Stocker, 40 hp is the "break even" point.
