Thinking of a LT1 swap on my 84 z28. I can use the same drive shaft correct? Or are they diff lengths?

 

diff tranny so driveshaft i believe but i hear ppl cut and weld on engineswaps when the driveshaft is too long or too short

 

What trans are you going to use?
Trans length is what determines DS length not engine

 

Why?
LT1 has std SBC bolt pattern so you can bolt up any Chevy trans ( within reason )
Early LT1's came with the 4L60 (T700) trans just like 3rd gen did

 

Tranny have different lengths some have short tails some have long tails

 

Well im looking at a 97 camaro. All I know is it has an LT1 with original rebuilt transmission.

Would the automatic 700r4 be capable? Thats what I have in now

 

the motor and trans will fit in without issue and you can reuse your ds. the motor and trans from the 4th gens are the same length as the 3rd gens and the 4th gen aluminum ds's are a very common swap for the 3rd gen steels.

 

Nice thanks for the info

 

Get the engine AND transmission. It doesn't make a lick of sense to put an old TH700 behind an LT1 - the LT1 has a "PCM" - "Powertrain Control Module" - that controls both the engine and transmission. The 4L60E in the '97 is superior in all ways to any TH700.

The 3rd gen torque arm and driveshaft are both interchangeable with the 4th gen units (as long as we're not talking about the early 3rd gen 3-speed auto and 4-speed manual transmission models). While you're at it, you might as well get the driveshaft out of the '97 as well, as many of them were aluminum, and had a damping ring built into the transmission yoke.

 

I didnt plan on using the 700R4 just didnt know you could use it.

Thanks Five7Kid you answered my next question about the ds
