Calling on all L-series engine experts.
Yeah- stalled and he kept the parts folks let him borrow to make this work - real nice.

75 280Z won't run.
TDC COMPRESSION STROKE!!!!!! Pull #1 plug and shove a vacuum plug that just fits the hole in there. Turn over motor till that sucker shoots across the room- you found compression stroke . Now line everything up

Build is looking good. Too late now but I would have mentioned that you could shove 14mm high impedance injectors in the stock manifold and they will seal. Probably a mute point if have a 11mm fuel rail. I’m running Audi 1.8 Bosch type now. As far as catch can , PCV, etc, I added a pic of mine . You said you run a catch can, probably plumbed the same way. There’s a few hoses there if you can pick it out. The hose off the intake is for the IAC . The can catches more than I thought. I like how you cleaned the intake up. I need to do a cable myself to get rid of the linkage.

There was a QC sticker provided on a separate piece of paper with an explanation of why it wasn’t on the damper, because the damper needed a protective coating, BUT be assured it was inspected. I will say they were very apologetic and sent a return label immediately. Customer service was good. Full review when I get another one

Well another set back or two. After staring at my valve train I realized my lash pads for the exhaust were to deep in the retainer putting the rocker too close to the edge. So I ordered a larger size and will sacrifice a little on my desired wipe pattern , but should gain more clearance for my rocker . Also, my BHJ damper came in , but had defects so I had to send it back. Check your parts closely guys ( didn’t sound right did it -lol). When you are paying serious $$ for performance stuff it shouldn’t have defects. ?

thoughts on head straightening
I was just trying to clarify your statement - not playing semantics. We started the thread talking about straightening ( flattening ) the head. I wanted to clarify you were referring to cutting the head on both sides and not straightening both sides. The last head I had done for someone I had 3 sides cut. Some early heads have some corrosion ( pitting) along the mating surface of the intake and exhaust can use a nice shave. It can get expensive when you start doing 3 sides . Anytime there is warpage on the head , both sides needs to be checked for sure. Yes the head has to be torn all the way down to cut the cam side of the head , but that’s just the way it goes if the cam don’t spin freely

Do you mean to say - machine both sides- Charles?

thoughts on head straightening
This was all part of the welding process to close the chambers on some of the heads . Again, I would only consider this process if I had a head that I had a lot of money and mods in and was trying to salvage it after it was warped by overheating . Shaving is the a better alternative if you have the room for P2V clearance - IMHO. Heads are plenty enough still, so unless you can straighten heads yourself, the expense of straightening is not worth it.

I attempted this with a head that was .035 warped. My problem was having the correct fixture to bolt the head down . Since I was just playing around I used a cut up L24 block as the fixture . The block surface was also warped in the opposite direction, so it worked well for this instead of shimming a flat surface . I heated all this is a pottery kiln. 350 degrees for 2 hours worked well. There was rebound effect that made it difficult to predict . The next try my buddy forgot the head was in the kiln and cooked the head . That was my last attempt. With what little you are doing I would shave it . Hell, I could have shaved the .035 and been alright , but I wanted to play with trying to bending the head. Make sure you slow cool it and don’t bang on it until it is fully cooled. Don’t want to loosen any seats . The head I was trying was a e31 that was a head I didn’t care about . Some guys here said I was crazy for thinking this would work, but it’s right there in the How to Modify book.

Sorry , I missed your post. Stock Felpro - so 1.25mm. Head has probably .025 shaved. .090 ex .120 intake

300hp out of L28 non turbo
These posts have come up before . Google 200 RWHP Hybridz and read so,e of those threads . 200 hp is much more realistic and if you haven’t driven a Z with 200 you don’t have the objectivity to ask for 300. 200 would be a hand full for a street motor. People that have ridden in my 155 rwhp car swear it’s much more. Gearing will help with the fun factor . The advice above is realistic. These engines aren’t cheap to get that HP goals . Cams, cam gears, harmonic balancers , pistons , valves , port work, hardware, engine control( ignition and fuel) , triples or EFI , $$$$$$$$$$$$$$$$

Okay- we’ll lash pads are available in most sizes . I wouldn’t modify any lash pad myself, I would just get the correct size .
-
L28+(maxima)47 build
So what size do you need? The lash pads are available . Have you done a wipe with stock pads?
-
L28+(maxima)47 build
Why would I remove material? I figured the size I needed and ordered the correct ones

L28+(maxima)47 build
Lash pads installed ! .525 lift and still room for the valves and pistons to share. Waiting on a adjustable cam sprocket and still debating on the balancer . Thinking about spending the $$ because I want to use it on my L32 eventually . Also waiting on some hardware to finish buttoning up things .
