Its a small world nowadays, most people will post but thats homework you'll have to do, as with pricing.
The conversions are a viable option when you think to build a pinto with comparative power will cost upwards of 10k unless you can do alot of the work
yourself. The conversion kits may be a bit of an outlay to start with, say 7k without shopping around but the engines themselves are a cheap as chips at wreckers, say $1000 to $1500 and easy enough to replace if they do go pop.
yes Engines, seem to be a dime a dozen for the Duratec at least, gearboxes on the other hand haven't seen many. i guess its part of the process research and patience.
