Well there are several cheap performance upgrades 2 suit your 250. To bring it on par with a VN commonhore is really rather simple, my mate has a 250 with stock cam, stock compression, but has added a 250 2V head with a 500 holley. This guy has no idea about cars but due to the persistence of me and my mates we've managed to get the car quicker than a VN manual. Now I believe the X-Flow head flows better than a 2V due to the crappy design of the 2V exhaust ports, centre 2 are huuge others are small. So the head you have should do the trick, A mild cam, say 20-50, can be had thru VPW for as little as 129.95 with lifters available thru KB engine parts for 75.00. Add say a 3.23 ratio LSD diff, get head milled to about 9.5 to 1 comp and a reasonable carb, XE weber flows 320 cfm, or a 350/500 holley calibrated to your engine AKA, dyno tuned or a hell of a lot of trial and error on the road mucking with jet sizes etc should bring your tina into the mid 14's with traction. All this should cost you no more than $500-600 with a bit of know how and a bit of axle grease from yourself. All thats left to add then is an Authorised GM Destroyer sticker on the back window.
 
I reckon it'll be easy as to hop up your corty.

Do you go on highways much? If not, you should get a 2 litre rear end for it. that'll have something like a 3.7:1 ratio. That in itself will own lots of things out there. It WILL incinerate any tyre you have on the back, too ;)

next up, does your corty have the 2 barrel carby? As mentioned before, it'll flow more than the stromberg.. if you dont have it, get it.. $150 later and you'll have a carby well matched to the stock crossflow. You'll need a fuel pump and a return fuel line, though.

Got a mate with a welder? a set of extractors will go good with the weber, too.. all of this can be found at a wrecker :)

I wont say it cant be done but Id would be very surprised if it would do mid 14 quarter mile times with only a 20-50 cam (milder than my 25-65) with those mods. In either crossflow or 2V maybe around 14.2 but the engine would need to be pushing close to 4800 rpm.
I think 14.2 is close to 0-60mph in around six seconds, quicker than a WRX.
 
Alledgedly this does 14.28sec quarter mile times and 0-100kph in 5.99 secs. Its a 351 Clevo COME engine package with a mild 208/215 at 50 cam which peaks at 4750rpm. Too peak at 4750 in a 250 2V or crossflow it would need to be at least a 214/214 at 50 cam probably even a 218/218 at 50 (they dont repond to caming as readily as most V8s (not a bad thing?)

I was merely going off the time that my friends mild 265 full weight VH valiant hardtop ran in very mild trim. E38 cam,10-1,comp,4BBL (600cfm vac sec edelbrock) through a 2in exhaust with 2.92 open diff. 15.1 @91mph. Wheelspin through first and second gear and a heavier car, in theory the cortina with traction should be marginally quicker, being 200 or so kg's lighter with a lower diff ratio.
