>...how tall is a crossflow from crank centreline to top of rocker cover (excluding oil filler)?
Looks like 14.5" from middle of crank pulley bolt to the top of the rocker - however I have the more angled cover which *might* be a fraction taller than the more square one and note that the thermostat housing is as tall as the rocker cover. Thats on on my engine at least - if the squarer cover is slightly lower than the thermostat housing is possibly the tallest part though you could always use a remote one if that was an issue I suppose.

Re: crossflow
The issue is how low you want to drop the engine into the chassis. If you dry sump it, or put a wider "T" pan on it, the engine can go lower.

Re: crossflow
I think if I went X-flow I would choose dry sump as the parts are readily available and it would help ensure it cleared. Oil tank could sit in the space in front of the fuel tank and behind the RH front wheel. I'd still be limited by the bellhousing and keeping gear box centreline parallel with the diff pinion.
I didn't bid on the Ebay engines - really need to see how the A Series runs this time around. I've all season to ponder the next move! Was looking at Swiftune's cams though...their SW23 looks a nice spec. without being too much of a screamer. 3 months to go to first race and I'm getting twitchy already. Any more thoughts on that test day Adam? Something in March could be good. We might even coax a few of the road Elevens out for a first trip of the season!

Re: crossflow
If you are running a big bore, 1380 engine, you can go more agressive with the cam. What I have found is that most people tend to go too mild on the cam, and don't use enough compression. If you go conservative, you get conservative HP. With the larger displacement, the cam acts milder than it would be with a 1275.
I run 10.6:1 compression, and use one of APT's scatter pattern cams. It works well. It is a vintage race cam, and works great as a hot road cam. Plenty of power, and it idles OK. No problems in traffic. When I rebuild this engine, I will probably go the next step up, or one of the newer grinds. More research to do.
Otherwise, go with a good vintage race cam for the road, and you will get more useable HP. I would ignore the hot road cams entirely. I use a 6500 RPM redline, with a cam that will make peak power near that number. My current cam will allow 7200 RPM. However, the power falls off at around 6500.

Re: crossflow
Charles, i've not looked at the car yet. Might try and get there this weekend - at the moment its finding time to get down to my uncles to work on it.
We're not rebuilding anything this year so hopefully everything is in working order, just need new belts and the FE needs servicing.
Anybody need a 6point harness? Ideal for trackdays but now out of date for racing (what a con that is!!)

Re: crossflow
Re. cam I'm thinking of someting closer to 300 deg duration (649 or similar). As you say they are not too bad with a big bore A Series. I'm running close to 11.5:1, so OK for CR.
Adam - kick the tyres, wipe the dead bugs of the wind screen and away you go! I'll see what events there are during March. Any preference for circuit?

Re: crossflow
hello,
measured the crossflow 1300.
Engine height above crankshaft 13 1/4" the 1600 engine is 1/2" more
engine height below crankshaft 7 1/8" 9this is crankshaft to lower part gear box.
Already shaved 1/2" off of the gearbox.
How does this compare to the BMC engine?
Thanks Cor

Re: crossflow
>and should be able to handle anything up to 155ish bhp, so basically anything you are likely to get from a xflow without spending £££ on it.
Umm feel I ought to qualify my own statement: the above assumes normal road tyres and xflow levels of torque. If you are running sticky racing tyres or something with higher levels of torque than the xflow I imagine you might be able to break a type 2 at lower bhp levels than 150 odd....

Looked oveer the car, its seems we cleaned most of it before leaving Spa last time which was a pleasant surprise.
Just need to do a nut and bolt check but should be good for March/April trackday. A localish track would be good, and not ridiculously expensive. Open pitlane would be good too.
