I am currently building my motor on my 280z, and I was looking at having the head chambers welded up. The issue I have ran into is everyone wants big money to perform this service. I was was wondering what everyone's opinion was on if should even weld the chambers, or if someone has a reasonable source to have this service done. My current build list is as follows: N42 Block N42 Head / Ported & Unshrouded .030" over ITM Flat-top pistons 280z rods w/ ARP rod bolts ARP main studs ARP head studs Triple Weber 45 DCOEs with Cannon intake Advance Distributors re-curved 280zx distri
I am starting to plan my engine build and would like some input on my initial parts selection/configuration I am thinking. I have two N42/N42 engines to pick from. My thoughts are as follows: Block Cleaned, bored, honed, new freeze plugs, ARP main bolts, ITM flat top pistons .30" ovesize (already purchased) Head Surface, valves unshrouded, mild porting. (*considering trying to weld up the chambers with a MIG spool gun) Cam (Either a Schneider 284-92F or a 290F) ARP Head bolts Felpro Head Gasket Fuel MSA triple Webers 45mm Ignition Considering a M
Due to a problem with my P90 head, its getting fixed due to a bad gas incident a month ago resulting in a bent valve and leaving #5 with 0 psi on a compression test. While its there I am having the cam go through a regrind to what he thinks will be a good setup for what im looking for (mild, good street setup). He said it will give a lumpy idle, and strong pull all the way up to 7000 rpm. He is a local builder and this is a spec he uses on carb'd engines. Any thoughts? 280 duration .480 lift 106 lobe center Valve Timing: Intake: .010 lift opens at 31* BTDC closes 31* ATDC (62*
