denny411 Posted July 23, 2003 Share Posted July 23, 2003 What year of 240 did the e31 originally come on? and what would be a fair price to pay for a stock used e31 that may or may not need rebuilt?(haven`t heard the car run) Quote Link to comment Share on other sites More sharing options...
yo2001 Posted July 23, 2003 Share Posted July 23, 2003 early 69-71 I think It's worth bux Quote Link to comment Share on other sites More sharing options...
denny411 Posted July 23, 2003 Author Share Posted July 23, 2003 This head may have been installed on a later 240 then. What is a good way to tell what year a 240 is when you don`t have the title? The car has a wierd looking console. No ashtray or storage tray in it, and it has a chocke lever where the ashtray would normally be. The car also has a factory wooden steering wheel. I assume it`s not a 70 because there are no vents in the hatch and it has the round "Z" sail panel vents, but the front bumper brackets look similiar to the ones I removed from a 73.

yo2001 Posted July 23, 2003 Share Posted July 23, 2003 You can check the VIN number (list is on Victoria British catalog) or the panel on the side of driver door. The head you sold me came off the 73 240Z I believe. (E88) E31 was before that so it might even on the early 72 Quote Link to comment Share on other sites More sharing options...
denny411 Posted July 23, 2003 Author Share Posted July 23, 2003 I looked but did not see any tag on the drivers door or door jamb. The car also has the original am/fm radio still in place. i`ll check tomorrow to see if it still works. I`m planning to buy the car to part out. it is rusted WAY beyond repair.

RedNeckZ Posted July 23, 2003 Share Posted July 23, 2003 If the vents are not on the hatch. It is most likely a 1971 240Z. You have described what is in mine. It came with the E-31 head. It was produced in late 1970 and shipped as a 1971 model. Keep looking for the vin plate, it should verify that. Quote Link to comment Share on other sites More sharing options...
denny411 Posted July 23, 2003 Author Share Posted July 23, 2003 I checked this morning and the vin plate from the door jam was removed as well as the dash vin plate. I`m going to assume that it is a 72 because the vin# on the firewall is 21000 less than a 73 240 that I bought a few years ago I bought the car this morning so nearly everything(other than body parts) is available. I suppose it`s time to move my post to the buy/sell forum, and start pricing things for sale. Thanks for the help guys. Quote Link to comment Share on other sites More sharing options...
texasz Posted July 23, 2003 Share Posted July 23, 2003 The E31 head was only avaliable on cars made in 1970, some of these may have been sold as a '71 such as my car but were still made in '70. Starting Jan 1, 1971 they moved to the E88 head. This info is taken from the Z-Garage website. Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted July 24, 2003 Share Posted July 24, 2003 OK, My '71 has quarter vents as later models, no hatch vents, the same console you described, AND a E31 head. It's VIN is 40000(really). I'm betting you have a '71. Quote Link to comment Share on other sites More sharing options...
texasz Posted July 24, 2003 Share Posted July 24, 2003 Check out http://www.zhome.com for more info on production info. Here's a good page from their site that has VIN and year/productions series info: http://zhome.com/History/DesignChanges.htm Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted July 24, 2003 Share Posted July 24, 2003 Also, the VIN is stamped into the fire wall above the brake booster. Right into the sheet meatal, so tag to be removed. Check the numbers on the block, if it is original(should match the one on the firewall), that will tell you if the engine has been changed. TexasZ, my car is a late production '71 with an E31 head. This is a numbers matching car, VIN# HLS30-40000. The '71 model year had many changes. At any time, you can find something un-ordinary. My '73 does have an E88(to be expected) head though.

denny411 Posted July 24, 2003 Author Share Posted July 24, 2003 The vin# from the firewall is, HLS30 133898 Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted July 24, 2003 Share Posted July 24, 2003 My december 1970 240 has the vents in the rear hatch. It is titled as a 71. VIN HLS30 17725. Definitely an E31 head. I think the E31 is cast right into the side of the head, just above the head gasket. Should be easily visible. Quote Link to comment Share on other sites More sharing options...
denny411 Posted July 24, 2003 Author Share Posted July 24, 2003 I do know that it IS an E31 head. could someone check to see what year the car is by the vin# ?(HLS30 133898) Quote Link to comment Share on other sites More sharing options...
Guest Al 260Z Posted July 25, 2003 Share Posted July 25, 2003 Sorry to rain on your parade, but I'd be very concerned about missing ID tags if you want a registered, street-legal car. Missing ID plates are typically the result of theft or other squirrelliness. Did you get papers with the car? Do VIN numbers on papers match number on firewall? You may have a hell of a time getting the thing properly registered if it was stolen. Good luck! Al Quote Link to comment Share on other sites More sharing options...
Guest JAMIE T Posted July 25, 2003 Share Posted July 25, 2003 I don't think he ever mentioned registering the car. Probably a parts car. In his first post, he asked how much would be a good price for a E31 head. Quote Link to comment Share on other sites More sharing options...
denny411 Posted July 25, 2003 Author Share Posted July 25, 2003 I bought the car stricktly as a parts car. It is rusted way beyond any hope of repair. Not even Fred Flintstone would want to drive it. The car does have some high demand parts for the purists, and good drivetrain parts. Quote Link to comment Share on other sites More sharing options...
johnc Posted July 25, 2003 Share Posted July 25, 2003 E31 heads are of some value to folks doing a restoration. They are no longer of much value to racers because their only advantage (compression ratio increase) has been negated by what a lot of L6 engine builders have figured out. Early E88 heads are now the preferred ITS head. Quote Link to comment Share on other sites More sharing options...
Guest Walkingpig Posted July 26, 2003 Share Posted July 26, 2003 I have the 2 bonnet vents, and the plate on the car says 7/71, and i have an E31 head if thats any help? and its unadvisable to turbo an E31? Quote Link to comment Share on other sites More sharing options...
Guest mikey_clark Posted September 16, 2003 Share Posted September 16, 2003 Where on the head is the stamp or number that tells what head it is? My brother has an old 240 engine laying out in the mud at his house. The intake side is covered with mud. At the back of the head (what would be up against the firewall) it has a #2 and a 3-18. Are there other numbers I should be looking for? I'm trying to identify the head to see if it's worth using. It was rebuilt not too long before it was tossed. It does have square exhaust ports if that means anything. The numbers on the block were hard to read, but I think the first number was 1?24. Couldn't make out the 2nd number, And the number on the right looked like 1023. Quote Link to comment Share on other sites More sharing options...
