\race aluminum blocks are made for race only, in that they have odd deck heights or offset lifter bores
Never a bad idea in any kind of engine. Steel insert are a must in my opinion. The Rodeck block seems to have a main web cracking problem when making 750 or more and the Chevrolet factory aluminum blocks don't have enough thread length in the head stud or main stud area and the mains are weak. Those blocks should be avoided unless its a low power application under 400 horse and 6000rpmCheck mains, be sure the threads will hold torque.
I've never heard or seen this before. Respectively have to disagree. I also assume we are using a good block. Dart, Rodeck SB2.2 or Bowtie or Vinney...ect. It's where most of my experience revolves around. I could be wrong outside this realmHP wise an aluminum block will make less then an iron block in the same application. . .sleeve movement = bad ring seal.
I concur Doctor.There is absolutely no down side to an al block...unless you count in that you need some different education in them.
Who would spend that much money on a block and put crappy stamped tin foil on it?Some of the racers I've talked to said there are sealing issues with the tin.
Wow only 400hp??? and 6000rpm... Hard to believe this ....johnsongrass1 said:\

I'll buy this. It's good information to forward.I never said race Aluminum blocks are made for race only, I said SOME ARE, and if he is going to buy a used block this should be somthing to check into.
