got a problem, not sure how to solve it ...
can someone advise me how easy it is to change DOHC sierra engine for Pinto
what modifications would i have to do?
My chassis are made to take SOHC only ...

Not sure I understand the question mate. Do you mean DOHC into a pinto chassis?

I have DOHC ford sierra, however my chassis are made to fit only SOHC Pintos ...
how easy is it to fit a Pinto engine instead of my old DOHC? would there be any problems doing that/ or is it straight forward?
thanx
