I decided to get some dyno numbers on my engine before it went back in the car after the "unplanned maintenance." The intake manifold and the heads had a bit of a port mismatch, which was corrected by milling the intake .080"
Unfortunately my dyno pulls were made before the intake manifold was milled and I didn't get any pulls after it was fixed.
410 Windsor
AFR 205's
SRP pistons 11.4 to 1
SCAT H beam rods
SCAT crank (internally balanced)
Jesel Sportsman 1.6 rockers
Manton Series 5 pushrods
Super Victor out of the box (Has been milled and ported since the dyno pulls)
Holley HP 950 prepped by Bigs Performance
FPA headers 1 3/4" tubes
Sorry about the poor quality of the dyno sheet.
Peak horsepower was 626.5 at 6300 rpm and peak torque was 567.9 at 5100rpm.
Cain, I got the dyno sheet. Thank you! I may have a zillion questions for you now though.
The biggest difference between our motors is I am running ported C9s I know
they are no where close to the AFR 205s but I didn't want to have my 17 year old son going to fast with out a roll cage. We have one in the car now though.
Nice numbers, now you said this was before the port correction? Either way nice numbers. I was building a 418w with sim specs, afr 205s, eagle internals int. bal, je pistons 11.1, didnt decide on cam yet, was about $6000 into it, nearing completion and an emergency came up, sold for $3000 Hope my setup was put to good use.
Yes, these numbers are before the intake manifold was milled and ported. My machinist thinks I might have gained around 20 horsepower with the intake work. It's hard to say exactly what was gained by the intake work. I wish I'd have snapped a photo of the port mismatch so you all could see just how bad it was.
In case anyone was wondering the engine made it's best power with 36 degrees total advance.
looks good cain. ill be getting my engine on the dyno maybe this week. heck its only been 3 yrs now since my 69mach1 has seen black pavement. way over due. hope to make some good#s this time??. pray. AFR 205s with a HR cam. 242-248-600-624-110 ed curtis grind.
The AFR's were milled .010" back in 2003 when I bought them because they weren't even close to flat when AFR sent them to me. They were milled another .010" and got a fresh valve job along with some Comp Cams 919 springs for this rebuild. Nothing else has been done to them.
The block is a regular run of the mill Ford block. I've never checked the casting numbers, but I think it's a mid 70's block. I can look at the casting numbers if you really care. This engine was originally built in a 69 block, but that one broke in a flywheel explosion a few years years ago. I transferred the guts into the current block and had it machined for zero deck. If I'd have known it was going to make as much power as it did, I'd have probably done a half fill on it, but it's a little late for that now. Typical Ford.....runs better than expected. I'm using factory two bolt caps with ARP studs and no main girdle. Chances are probably pretty good that I'll break this block. Probably won't last too long when I turn on the bottle. Hopefully it will live for a while. When it breaks I'll either get a Dart block or step up to a 385 series big block.
I know this thread is quite old but I thought I would ask anyway.
I'm building a 408 very very close to this guys 410. I only hope it will make 625 hp. I would be thrilled. It's going in my sons first racecar. (He has driven many others before)
The combo is
Stock Roller Block Half Filled
408 Windsor 4.03 x 4 flat top
AFR 205's 58cc chamber
Quick Fuel HP 950
Super Victor out of the box
SRP pistons 12.5 to 1 SCAT H beam rods
SCAT crank (externally/balanced)
ARP Head Studs
Canton Oil Pan
Canton Main Girdle (beautiful piece and no mods to caps)
Canton Windage Tray
I'm setup for oiling mods(everything is taped) but I don't know yet weather I will restrict or not. I ceratinly don't think is a necesasaity on this block. I will block the four valley center drainbacks

My question was did anyone ever hear from Cain again? I wonder how his combination turned out?
With that big drag roller cam and high compression you will make 650hp for sure. I'm making close to 600 crank, and my cam is a smaller street roller xr292r, and my compression is lower also at 10.5:1.
I'm still around. The ol Windsor has been holding up fine. The heads and rotating assembly are nearly 10 years old now. If I were building another one, I'd start with a Dart block.
My local tracks are 1/8th mile. Back when I was running the toploader it would usually go 6.8x at 100-101 if it wasn't 100 degrees out. I usually ran around 7.0 when it was real hot out.
I did squeeze a couple 6.7x's out of it at a little over 102 when it cooled off in the fall. Since then I've put in a Jerico which I'm hoping will shave off a little ET. I've found a couple mechanical problems on the car since the Jerico install which should help as well. I didn't get to the track at all last year, but this year should be a different story. Gas milage is really ****ty so I usually only race at the two tracks close to me. I'm excited to run on the bottle this year with the Jerico. I'm hoping to weigh the car this year as well. I'm guessing it to be around 3500 with me in it.
I'm looking to do a 408w .060 over ,11.5:1,vicjr int.,t-5,3.73,750 dp and i will drive it up to 200mi a week and want to go on vacations with it looking to get 14mpgs if possible but i love the fast reving solid roller do you have any cam sugistions my heads right now are ported e7 would like to save for afrs
Nice job Das Jager. Looks like your car is running pretty strong with the new heads. I am inclined to agree with you. If I build another one it will not have AFR heads on it. It will likely be a 4.125 bore Dart block with a set of TEA highports on it.
I'll have to blow the current engine up before that build happens though
