こんにちは, It's been a while since I have been on but we are finally in our new home and I have had some spare time to pull the z apart. So my question is, what would be the best build for a n42/n47 na set up? That's the block and head I have right now and I believe it shouldn't be a bad place to start. Any of you have experience with this build? I have read mountains on the n42 head but I can't find much on the n47. From the few things I have found some good ideas might be replacing the dished pistons for flat tops. From familiarity on the head I assume it would bring compression up to about a 10:1 and you would have to be crazy to not put a new cam in after that. (270 - 280 degrees on that cam, correct?) After that you would want your head matched up to your exhaust and intake for better flow. What else might you want to do? I currently am running round top SUs and the stock exhaust. The exhaust will be replaced for 2.5 and, if dreams come true, I will switch to some triples. What ideas can you folks dream up for this motor/head? I am not looking for any crazy power upgrade, just something to put a smile on my face. I wan't to make sure I can still daily it without putting racing fuel in it. Thank you in advance, the support I get from this forum by far makes it my go to place.
Hi, so I am about to embark on an engine rebuild and am planning to get a cam regrind. I have an l28 with an n47 head and roundtop su's. I have 2 questions. 1.) I heard the e88 and e33 heads had cams that were more suited to being reground, is this true? Is the n47 cam ok to get reground? 2.) Does anybody have experience with any cam grinders in the bay area? Or if not is delta cams good? Thanks!
