71 240z strange overheating/cooling system problem.
If you don’t know how much them what shims would you use. You could measure the head thickness and figure from there- but I wouldn’t bother . I’m running .050 cut on my 31 with no shims , but cam gear advanced and chain guide adjusted . yo

Stroker 3.1
I knew you built your own motors - that’s why I asked. My Rebello will come as a kit for me to assemble . Hopefully I’ll have another engine build or two under my belt before I do it. At least he will do the block prep for me . I will still be a bit nervous will my ‘ investment’. I do and did enjoy carbs- but wanted to prove this old dog could learn some new tricks . And when and if I go pressurized with an L motor - it’s about required

A/F ratio for L28
Right on the money . Damn AFR gauges are a great tool but you find yourself about having a wreck watching the damn thing and obsessing over it. I say for the most part these engines sound better and run better a tad rich - but might just be me.

Stroker 3.1
What you spend in $$ will come back to you in the versatility to tune to your hearts desire and not smell gas in your finger again ! Then there’s having a lean idle and no smells of float bowls venting into the garage . You can make a tune change while watching the evening news in your lazy boy ! Weather change? No worries , EFI got it covered. So have you been doing any hands on assembly with your motors or does Eji do it all?

Bought # 4858
Not much left if the block - it’s now going to be a test jig for straightening warped heads . The pistons faired out better - my machinist checked them out and said they were good to go as far as still being round! One of the pistons is stiff on the pin- but he showed me with just some warm water running over the pin it loosened up . Now the question is to use the pistons on what? These are 86mm pistons so do I punch out another p30 block or .... ? Sures sounds fun but not sure I want to go that route . I have another p30 block sitting in front of me now and it’s tempting . Crankshaft is getting checked but I think it’s okay after a polish.

Stainless steel hard brake and fuel lines vs standard steel hard linesl
Being pre-bent , I would go SS. Bending SS line is a bitch especially when you start getting to bigger lines like 5/16” or bigger . You can’t just reach up under there and tweak the bend with your hands - unless you are incredibly strong . i just did 3/8” SS for supply line in the stock position and it was really tough especially when you have to pull it out every time you need to tweak it

L28 Stroker Build - I need your advice :-)
ISKY sent me the wrong card with my cam. I spent a day turning my engine over and over and rechecking numbers to try and make them come out. I finally got him on the phone and we cleared it up. It’s frustrating if you don’t do this a lot or are not confident of your skills- you swear your doing something wrong when your not. Not easy telling Mr. Iskerdian his cam card doesn’t make sense . I also never hit my numbers exact. Lots of slop in rocker arm ratios and other variables. If the cam grinder says they are good numbers then go with it

Rear disk brake conversion
If any kit requires you to give up your parking brake and you have a manual trans- you might think twice. I miss my parking brake and it adds to the cost in most disc upgrades . Bigger front discs and rear drums in excellent condition should be adequate for all but racing

14x6 Rims
I have not found such a stamping other than the pic I took. I guess I need to keep looking. I took the measurement letting folks know that these were not the earliest rims which are only 4.5” wide . Yes these are 5” wide rims i tried finding a pic of this stamp date but didn’t have any luck

Nissan Datsun 240Z 1972 L24 (N.A.-tuning)
I just took a L24 apart and bores were drilled( bored) to 86mm - which I guess is not unheard of. Maybe not recommended doing before sonic testing. You don’t have to go huge bores to make fast fun engine . Put money in the cylinder head . 150 hp at the rear wheels is fun car with correct gearing

First drive in the z in 25 years.....impressions.
Expecting any kind of refinement from an abused 45 year old car is unrealistic . Exhaust smell issues are a problem when not addressed on these cars. There is a ton of info available on this issue. These cars are easy to work on and have good support and are relatively inexpensive to work on. And as your said, the smile is there when you drive it. Dodgy electrical is from abuse and age and just takes a little effort to set right- but it’s not an old English car. There’s hardly a better true classic sports car for the buck these days . Good luck. Also make sure the hatch inner vinyl panel is in place and sealed . Exhaust will suck in from there Sent from my iPhone using Classic Zcar Club mobile
