Steve_Farrimond Posted February 28, 2013 Posted February 28, 2013 aren't all blacktops big valve heads? in comparision to the silvertop I thought they were bigger.
Terryathome Posted February 28, 2013 Author Posted February 28, 2013 Steve, the 1.8 engine is coming out and being replaced with a new 2.0 Zetec. Terry
Steve_Farrimond Posted March 1, 2013 Posted March 1, 2013 are the heads different? I thought it was just the bore size of the engine and then the cams?
Terryathome Posted March 1, 2013 Author Posted March 1, 2013 My 1.8 has hydraulic and the Blacktop is shimmed type, I also think that the valve diameter is different and if you swap say 1.8 for the 2.0 a few galleries are different. Terry
Steve_Farrimond Posted March 1, 2013 Posted March 1, 2013 yea the silvertop 1800 has a different head to the blacktop. as I understand the blacktop has larger valves to the silvertop, and to compensate the blacktop has different pistons to the silvertop allowing the space for the valves. you can put a silvertop head on a blacktop, but due to the clearance of the valves you can't put a blacktop head on a silvertop.
Wesley Posted March 1, 2013 Posted March 1, 2013 Do you know if the cam cover from a Silvertop will fit a Blacktop?
Terryathome Posted March 1, 2013 Author Posted March 1, 2013 I don't believe 1.8 will fit 2.0 But back to the question, anybody got a head? Terry
