The weight of the rotating assembley and the rpms are the most important thing hear. The blocks try to split and do split down the number 2 and 4 mains which causes loss of oil pressure and bearing loss. You should have no problems with what you are doing. Like I said before we have seen these blocks split at 550 to 600 HP with rpm range in the 7000 range, these have been drag engines that do nothing but turn this rpm time and time again. Use the 2 bolts block with main studs and balance everyhting good and you will have no problems. Keith |
Excal, maybe falling on my own sword on this one ... but... if the top oiler's
oil galleries are the same as the non-crossbolted FEs then that oil gallery (as Keith said) would be a weak spot, as you said ... making the T/O block inherently "weaker" than the S/O block.
If I'm making the correct correlation here then, according to Keith, I'm wrong and you're right.
