gjc5500 Posted August 2, 2009 Share Posted August 2, 2009 Two days ago i was helping my friend sell a car to another friend of mine. We went around back for a smoke and BOOM. 350 sbc just sitting there. blah blah blah, it is now sitting at my house for free waiting to be built and put in the z. Working on shorts amounts of money but wondering what the cheapest trans is that will work with the z (auto or 5spd.) Quote Link to comment Share on other sites More sharing options...
jnewby Posted August 2, 2009 Share Posted August 2, 2009 Th-350 is the cheapest in most cases, with a 3 speed auto you will pulling a lot of rpms on the highway, trust me you want either a 4 speed auto or a 5 speed manual. Quote Link to comment Share on other sites More sharing options...
gjc5500 Posted August 2, 2009 Author Share Posted August 2, 2009 I was thinking about the 700r4 but i cant find one cheap(gonna rebuild it myself). Quote Link to comment Share on other sites More sharing options...
Pyro Posted August 2, 2009 Share Posted August 2, 2009 you are opening a can of worms with a V8 conversion. Getting the engine and trans is the easiest part. if you don't have the money for a transmission then you will not have enough to do a good swap. And your car will sit for years then end up being towed to the junk yard. If you are short on money then you would be better off just adding a turbo to your current datsun engine. Your first V8 conversion always takes much longer than you think and cost much more than you plan for. Quote Link to comment Share on other sites More sharing options...
gjc5500 Posted August 3, 2009 Author Share Posted August 3, 2009 I just got the motor for now. i plan on building it out of the car and getting everything for the swap before i pull my old motor out. I still am not gonna start the swap till i get another car to drive while my car is down Quote Link to comment Share on other sites More sharing options...

Lol..this is so the truth. The only reason i have a TH350 in my car is because i got it for free(and it only had 1k miles on it since being rebuilt by a really good local shop), and because i dont drive too often on the freeway. When you couple my 3spd auto with the 88NA z31 rearend ratio of like 3.9:1...well...yea.... you get the idea. On the plus side, 45mph crusing will have to be a MUST! no more speeding tickets.
