I checked the FSM, and I can't find the original spec in there. Does anybody know the original spec from the factory for the head height in 240Zs? I found a number (I think it was around 4.245") in the How to Modify manual, but I'm not confident it's correct as I have two heads that are...

OK, the early 240's came with a different style wheel cylinder in the back than they had from 1972 on. For racing is there any performance or reliability difference between the two styles?? We have been using the newer style wheel cylinders, but have a number of early types that are ripe to...

I hope I don't look too stoopid here, but we had an issue that came up in my drivers school a couple of weeks ago. I kinda think this should be covered in the GCR, and I wanted to canvas everybody here for their opinion. We had a double yellow come out, and the safety car picked me up...

FINALLY we are back out on track following our rebuild, and mostly the car ran very well. Tim got his first race in, and by tomorrow should be one step closer towards pulling off those x's. He had very good drives today, and by the end of his race today was turning laps within 6.5 secs of the...

Well, we are finally almost done with our re-cage, and almost all the parts are back on the car. Hopefully this weekend we will be running the new motor for the first time. I was just wondering how you guys break-in your rebuilt L-6 motors for the track? Does it need to run under a load a...

We are rebuilding a motor for our z, and want to put ARP rod bolts in it, but I'm not sure if the motor we are rebuilding has 8mm or 9mm rod bolts in it. Am I correct in that the rods themselves are different, meaning you cannot use the 9mm bolts in a rod that originally had the 8mm bolts? If I...

Ok guys Tim ran the school at Homestead two weekends back and did well and was signed off, but we fought a fuel delivery problem all weekend. The car has a stock tank which was refurbished, but it was still full of garbage that is clogging our fuel filters. In addition we think our more...

Does anybody out there have experience with the NT-01 tire in the rain yet??? If so how have they performed? My brother is running his school in two weeks and we will be running the Nittos we have been using in PDX's. I wanted to have an idea how they perform in the wet ahead of time in case it...

Does anyone have experience with the Arizona Zcar aluminum racing radiators? Based on the responses on the oil cooler thread below we are replacing our stock radiator sooner rather than later. I know a Chevy roundy-round radiator can be adapted to the z a little more cheaply, but time is going...

Ok, I have some more newbie questions. Our car came without an oil cooler, and at our track days water temps have gotten a little higher than we would like(220), so we are going to add an oil cooler to the car. I don't have any idea what size cooler to go with though. I'm looking at the...

My brother and I are getting a new set of SU's for our 240, and have a question regarding which manifold to use with the carbs. I know 240's came with n-46, e-88, and n33 manifold at various points in it's production. I've read the general internet conjecture about these manifolds performance...
