d3c0y Posted May 18, 2011 Share Posted May 18, 2011 Hey Guys, I'm building an as close to 3.0L as I can get, high rpm, forged internal L28 with a stock stroke. I have both N42 and F54 block at my disposal and want to know definitively which is the best one to go with baring in mind it will be running an 89mm - 90mm bore size. I searched as hard as i could on this one and didnt really come up with anything solid on the subject other than a few suggestions the N42 maybe the way to go. I thought a thread with all the info in one place would be a handy thing to have anyway. Thanks Jake Quote Link to comment Share on other sites More sharing options...
Tony D Posted May 18, 2011 Share Posted May 18, 2011 It's pretty solid, and has been since the mid 80's. The N42 has far thicker walls and for an engine not using sleeves it's the choice for big overbores. Quote Link to comment Share on other sites More sharing options...
