4.6L alluminum block questions
I was debating whether to buy a 5.0 or a 4.6 for my 89 rebuild project. I had an import with an all alluminum block and had problems with gaskets because the alluminum warps when the temp changes. Do ford engines have this issue. Was I just too hard on the engine?

The ford v8 blocks are made better than an impot casting, also keep in mind that a cobra block is designed to be run hard and built up. I wouldnt worry about the Aluminium block, even the one from the explorer is a good base.

The teksid block 96-98 and a few 99s is the one which was imported from italy. That block has been used in many high power applications with great results because it's a better alloy and has stronger ridges in the valley to hold it together. I never hear much about warping with 4.6L aluminum blocks (any of them) so I'd have to say that it's likely a non-issue.
The question is, what kind of power are you looking for? Have you considered a 5.4L?

Actually, the reason I was resorting to the 4.6 was because the 5.0 ho hi hard to find and everyone wants too much for it. I'm rebuilding a 1989 mustang and need engine and transmission. Horsepower must be over 200. I have found a 5.4L Triton in a newer f150. What is the best engine to use? THat 4.6 is out of a 1995 cougar, by the way. I don't know if it's iron or alum.

When I was looking at the 5.4 I was a little concerned with clearance. The ford trucks always had bigger intakes. The trtin is supposed to push around 235hp, which would deffininitely be do-able. performance parts are a concern aswell. I have only done in-depth research on the 5.0. A lighter car would be faster. What do you guys think would be best?
