410 Windsor with AFR 205's

[Cain]

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)

Solid roller Grind# FW 4293S/1477 SR110.0
Valve adjustment .020 intake/ .015 exhaust
Lift .641/.649
Duration @.020 291/288
Valve timing @.050
Int. 22 BTDC close @ 56 ABDC
EXH. 61 BBDC close 15 ATDC
107 intake c/l
110 lobe sep.
Duration @ .050 258/256
Lobe lift is .401/.406

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.

Thanks

looks good

Nice looking motor, I'm looking to build a 408W to put in my Galaxie.

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.

But oh well thats life

Very nice!

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.

[gabe1530]

those are some really nice numbers for that missmatch!

do the afr's have any work done to them or are they straight out of the box?

[Cain]

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.

Hi-
Are you using a factory block? If so, what mods have you done to it (aftermarket caps, hardblok)?
Thanks,
Greg

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.

wow no girdle with nitrous in the works with that much power wow, let us know how many passes it lasts, im interested in knowing lol

[tonys10sec306]

it will stay together

[Thordane65]

Very very very nice.
Cant wait to hear it.
