[QUOTE="Boosted 03, post: 1570136, member: 16265"] Sean Hyland motorsports/ How to build a High Performance 4.6 Page 6 (Cylinder Blocks) "We at Sean Hyland Motorsports have successfully used the '96-'98 Cobra Aluminum blocks as a basis for engines of up to 1500 hp. Block, PN#F6LZ-6010-AB, was also used in the '93-'98 Lincoln Mark 8. Origionally this block was cast in Italy by Teksid, a supplier to Ferrari and others. This block is cast in Sae 319 modified alloy aluminum before it is heat treated and aged to achieve the desired characteristics. Overall, we have achieved good results with this light weight (85.40lbs) alloy block." Page 7 At this time, we have not used the later block for any extreme horspower applications, and some attempts by others have resulted in block failure. Our recommendation is that early blocks (96-98) is the best foundation for power levels above 900 hp, although the later (99-up) should certainly be adequate for moderate power levels of up to 600 hp with proper pre. Page 6 The late model blocks (2001-up) are a lighter weight (80.40lbs) casting using SAE 319 modified alloy. Page 11 (For inquiring minds that want to know) Cold start up Knock One of the challenges with the 4.6 liter engine is the fact that the piston is pulled so far out of the bore at the bottom of the stroke. The largest piston diameter comes clear out of the bore, allowing the piston to contact the cylinder wall on change of direction, creating noise when cold.
