Dont know if this has any validity, but I'll throw this in here and let you guys make of it what you will. I have a 76 model 900 Kaw. bored to 1132cc 7.8 compression MTC pistons with a Blake Enterprises turbo kit (draw thru) with a Bill Hann pressure retard electronic ign. It uses a Rayjay 302b25, running a 38mm round slide mikuni with an acc.pump. This set up has run 20lbs on 93 oct. with no pinging. I dont remember the ign. settings because it has been sitting in the garage with 1989 plates on it.

Around here 240s are few and far between and I have not ridden in another 240. The car really feels good, I am very pleased. 174000mi. and not a puff of smoke ,and 151-156 psi on all 6. I wish 1st & 2nd were a little taller cause they seem to go by quick. Now when I first got it going I had a problem with the rear end so I found one here to get by on ,only it was a 3.54. Third gear was quite nice but 1st and 2nd went by really fast. It seemed just when you got going you had to shift and shift again.I have been thinking along the lines of a close ratio 5 speed with a 3.7 If I remember correctly that gives a little taller 1st and 2nd and a shorter 3rd and 4th and of course 5th for the hiway.Another factor in my thinking along these lines ( which I haven't mentioned) is I have a 280 motor I'm planning on building in the next 18 months. I have a p90 head and a maxima flywheel so far.With a little mild head work, a little more compression, a mild cam and a 2.9 bore ......I am hoping that gearing will fit right in.What do you think ? maybe 180-190 to the wheels.

That is a nice link.... thanks. This may be a long answer to your question JM. As of now my 73 is stock (engine wise) I have changed to 71 round tops, crane 3000 Ign.and crane coil, Headers with a 2.5 inch exhaust and removed the smog tid bits, single groove crank pully and Amsoil in the rear & tranny. To me the car runs great! but I am comparing it to my own memory as I once owned one just like it 31 years ago and it did not run this good. I have only had this one running since early June. My memory reminds me of the huge gap between 2nd & 3rd. I have looked at the ratios of the 5 speed and the spacing is better, but in studying them it doesn't seem enough, but I have not experienced one first hand and I am most likely wrong. I have no intentions of drag racing the car.Just finding a straight stretch and letting her RIP thru 3rd is cool enough for me,any more than that and your pushing a 100. I'm almost 52 and 90 or so is fast enough for me and the officials ( I am very wary of when and how I do this) so I'm thinking the GAP would be better between 3rd & 4th since I am not planning on abusing the last 2 gears like the first 3. BTW the gap does not seem quite as bad with this car, I'm sure it's because it has more pep. .... I do appreciate all your comments,questions,suggestions, or what ever.

It sure would be nice if it were possible. ..... Anyone else have any ideas?

Mr. JM, thank you for input. I had hoped that you would be one of the people to reply as you seem very knowledegeable on most any Z subject! I supected that might be the case but had not taken a trans apart yet to investigate the possibility.

Does anyone know if gear sets can be swaped? ie 3rd gear set from a 73 4 speed into a 81-83 5 speed?

For those of you who have experienced it , can you describe just what it feels like when it happens? Thanks!
