Blacktop I've always thought had stronger internals....

why do you want build a zvh??? just build a full 16valve blacktop 350hp is east to get

as above just go full zetec, get a blacktop give jano a call and buy one of his piston/rod combo's and bolt it all back together again with a set of ian howells valve springs in it and with right manifolds and turbo a nice reliable lag free car can be had with 300-350 on tap, as far as i know blacktop is stronger in every way bar main caps but as of yet no one's had a set go in an engine with anything under 500 bhp but oil pumps in silvertops is a problem when revving them hard just look under luke's resto

would you need aftermarket management or would a zetec turbo run on fiesta efi?can you use a standard rs box?(sorry for the high jack)

silvertop are more common for zvh, sump pans are easier to sort to avoid the exhaust.
probably more but can't seem to think of why i went with a silvertop bottom end.

personnaly i'd run aftermarket stuff but it is possible to run it on fiesta stuff with right chip of msd
