Ford 200 C4 Auto, Cam advice

[xrwagon]

hey guys its my first post here, i am from Australia down under, i have a 1967 XR Falcon Wagon, original drive train is still installed and motor has never been out of its mounts, head has been done up for unleaded fuel and thats it. So Far i have added a set of Hi-Tech Headers and a 2.25 exhaust and Hooker Aeroflow muffler, dumped before the diff, my plans at this stage is to do a 250 2V head conversion and rebuild the bottom end if needed with a new hyd or solid cam, my question is i have been looking for a C4 Auto, i have a 351 26 spline auto which i know wont fit, but have been advised a windsor bolt pattern will fit my 200, do i need a 200 bellhousing or do i need a windsor, i wont be mucking around with pre 1970 boxes and nothing less than 26 spline so when i do get around to doing a Windsor, i wont have to change boxes. Any pics of C4 or bellhousing would be much appreciated. Now cam advice, i have read about guys using the comp 260 cam, and clay smith cams, is this relevant to the log head or a 250 2V, its obvious a huge improvement to place the aussie 2V head on, so i want to cam it accordingly, my motor is a 7 main, 5 freeze plug motor. I was planning a bore if needed with flat tops, the cam, ARP rod bolts (Windsor?), new balancer, roller timing chain, balanced, with a cleaned up 2V head, not sure how much to deck the head or block as i may run E85 fuel, alloy manifold and 350 or 465 holley, not sure if a 4 barrel will be to much. My auto was going to be a stage 2 shift kitted, 2500 stall, or matched to cam, billet servo, extra clutchs and a deep pan, diff wil be a 28 spline bw78 or bw75 4 pinion LSD. I wanted to run drags where i live, we have a meet called the 6 Banger Nats over the eighth, i was hoping for a 10, maybe a high nine, in my wagon. Also should add that i will do electronic ignition.

8) firs unless you have a low mount starter, the 351w bell will not fit the 200 so you do need a 200 C4 bell. the 200 bell will fit the C4 trans though. you will need a torque converter from a 70 or later 200 to fit the 26 spline input shaft though.

as to what cam to use, if this is going to be a daily driver, them you want a cam that will work in the 1000-5000 rpm range, and with the automatic you want the lobe separation angle to be 110-112 degrees. classic inlines has a couple of cams i recommend, either one is a good choice;

1: http://classicinlines.com/proddetail.as ... 264-HSP-10 also available in 112 lobe separation

2: http://classicinlines.com/proddetail.as ... 264-HDP-10 also available in 112 lobe separation

either cam will do nicely

If you have a stock stall converter go with the 112 L/C
If you have a looser converter then the 110 L/C might be a choice. Nothing worse than having a tight converter strangle an engine at curb idle in drive due to low idle vacuum.
If you want a smoother idle consider the isky 262 camshaft which will give you more low end & midrange torque.

The above recomendations from rbohm for cam are the ideal. You can't go wrong with the Clay Smith cams, although Kelford and Crow Australia will make them as well.

All the following info is Aussie specfic, and won't make any sense to those of us from North America.

The US stuff above is relevent in this specific case, but Fords Broadmedows design team from 1966 all XR Falcons went to a uniquely the early Fairlane Compact 221/260/289 pre 1965 160 teeth flywheel and flexplate ring gear, and a specific to Australia bellhousing.

The 1966 to October 1980 Aussie I6's ran the same separator plate, same ring gear, same starter motor, and same automatic transmission bellhousing. And the same US Windsor 302 based C4 transmission with a specific Australian cast bellhousing.

(This allowed the Australian Fords to use the bigger clutches and V8 style torque converters. Prior to that, the 1960 to 1965 Ford had lots of clutch problems in the bulldust of the outback. The bellhousing change was also to allow the co-op Borg Warner gear manual and automatic transmissions that Chrysler Australia used on its compacts be co-sourced from the same supplier. The C4 on Aussie 170/188/221/250 i-6 sixes that were used were always US made imports, and the "C10" Cleveland 302 ran a US pan fill gearbox FMX style gearbox which cannot take the "C7/C8/C9" i6 bellhousing).

Get any 1972 XA 250 to Iron head 3.3/4.1 XD Falcon/(1980 Government issue Fairlane 4.1's had them) C4 option transmission bellhousing.They were supplied for Taxis and later model tow packs in the XC and XD series, because they were more reliable than the standard Aussie made Borg Warner 35 3-speed. When the 3.3 and 4.1 alloy head came out in October 1980, the US C4 option for sixes was no longer available expect as a special service retro fit from dealers.

If your using a US import C4 gearbox, it has to be the separate case Windsor 157 teeth item used beind 1970 onwards 302's. The US 170/200 engines found in Mavericks, the 200 sixes in Granadas, Monarchs and Fox bodies with the high mount blue i6 is the same, but runs less clutches than the V8 trans. So there is a huge supply, but you have to use the Aussie iron C7/C8/C9 I6 bellhousing.

The flexplate to use is the metric or imperial 160 teeth item from any 1970 to 1992 six cylinder Falcon, but you'll have to slot the six holes to move the Pitch Center Diameter in to 2.75" from the stock 3.00". There are C7, C8 and C9 C4 flexplates, but they are rare, and its easier to slot the common tall deck 200/250/3.3/4.1 flexplates.

Asside from that, its pretty simple. Stock stall ratio for a C4 i6 converter is 1650 rpm. Kayver in Australia make 2350 and 2500 rpm stall converters for a more hotted up six, and I'd recomend one of those.

Thanks for info mate, i think what i need to do is use a V8 Windsor box with a six cylinder bellhousing. I have a clevo box but swapped it for a windsor box, just waiting on pics to see whether the guy is correct.

I had my stock converter tweaked and they were able to get it to 2200rpm.
