Re: 3speed to Nv 3500 swap
Hey guys! I am new to the board. I just got a 68 with a 250 6cyl and a 3 speed in the floor (converted from column by PO). The rear-end is 308. It is a nightmare to take off in. I would love to convert it to a 4 speed with a bull-dog, or a late-model 5 speed. However, I am not sure what to look for. Any suggestions?
Thanks in advance. |

BTW, one of the reasons I was taken aack was because I knew the S-10 NV3500's have a long tailshaft, longer than the 1500 NV3500's, probably to help driveshaft angles, and I had previously planned on using one of those in order to change to a one-piece shaft and feel comfortable--but less cost makes me even more comfortable

Re: 3speed to Nv 3500 swap
This is probably a dumb question, but, is it necessary to use the hyd. slave cyl or,, can one just take out the old 3 speed and install the 5 speed and use the existing clutch, bellhousing and linkage? I have no complaints about the clutch pedal pressure so I might be interested in the swap if its just a trans. change. Thanks

Re: 3speed to Nv 3500 swap
I may not be doing this as soon as I thought, the pieces just aren't falling into place in time :-P but I found out a few things. There are different input shaft lengths to consider and the VSS signals go direct to a speedometer in the early models but have to go through a computer first, after '96. Not giving up, but it just won't be the one-week, bolt it in and test it deal I was hoping (dreaming?) it would be

Re: 3speed to Nv 3500 swap
Hey elf, I don't know what it's actually called but I had pedal assembly from donor truck. It kinda looks like a rivet head on the inside of the
Pedal arm. I simply ground the head off and took a hammer and punch and knocked it out. I then took my pedal drilled a hole in it inserted the pivot (what I'm gonna call it) then welded the back side of it the the pedal arm. If there's anything I can help you with Im me Frank |

Re: 3speed to Nv 3500 swap
As far as I know you'd have to go hydraulic the trannys I rhave seen are 1 piece with bell housing made on the trans.

Im in the process of doing this swap on my 64 Chevy from the sm465 to th I got a 94 Chevy parts truck. this tread has been real helpful the e nv3500 crossmember out of the 94 works just had to cut it narrow to fit but it looks like it looks like it’s going to work. I do have to get drive shaft shortened but I think when it’s all done it will be a nice weekend crusier

Thanks previous owners UGHH,
Just ordered my BN pre-filled M/C - HYD LINE - S/C - ASSY rockauto had a dorman for cheap! Oreilys has one listed but i called and they said they will have to get back to me...special order... Now stripping the new high hump piece i got up and welding the 4x4 hole (wont need that!!) and waiting on word regarding the correct spot needed for the nv3500 shifter location. You guys rock, thanks for all of the info!! |

Re: 3speed to Nv 3500 swap
There are newer styles of the nv3500 that you have the slave cylinder IN the bellhousing, but as far as i know 88-95...ish have the mc and sc outside tied together

Re: 3speed to Nv 3500 swap
Saw the picture above and inspired me to make my shifter stick look stock.
Instead of using the ugly bulky looking 90s shifter stick! now i can use a boot from our era!! I made it so I can screw off the 60's stick! Thought I would share. oh hey look, five bucks! (cool story huh) |

Re: 3speed to Nv 3500 swap
Okay, tried to throw in the motor and trans, but is hitting on the original crossmember, where the slave cylinder mold on the nv3500, ta2ed, you did mention the tailshaft area is different, im not there yet, but did you have to cut or remove the original crossmember?

Re: 3speed to Nv 3500 swap
Stupid me, no need for the original Saginaw trans crossmember. Removed, I'll stop posting on this thread since nobody even wants to do this swap anymore! Hahaha but for anyone who does I hope my posting helps!

Re: 3speed to Nv 3500 swap
Hey Elf, how's it going? Did you get your trans swapped out & on the road? I've been busier than sh*t working on my k5. Have made a lot of headway, but still haven't gotten around to swapping out the trans yet.
