It will "bolt up", but there is an issue with the torque converter. You will need to either have a standard torque converter machined/welded, or you will need to find the special torque converter that came on a 151/TH350 setup from the factory. I do not know if one actually exists, but I am looking.
Yes, assuming the TH350 has the Buick-Olds-Pontiac bolt pattern. A Chevy TH350 will also bolt up, but you will need an adapter from B&M or another supplier.
you can get a pointer at many parts suppliers such as jegs or summit. it will be chrome but will still do the job. bolt on to the engine and then set timing.Just a note. A TH350 is a transmission. You can not time a transmission.
The Chevy 283 engine has the standard bellhousing configuration and is compatible with transmissions that bolt to first generation small blocks. The automatic TH350 transmission will fit the 283 engine.
As long as the TH350 is from a Chevy....yes.
Yes it will, it is the same bolt pattern.
Pump assembly to case- (5/16-18) 15 ft/lb
Yes, you need to open up the transmission and replace the or swap the output shaft. Then bolt on the shorter tail housing.
Any automatic trans from Buick, Oldsmobile, Pontiac or Cadillac will bolt right up. A Chevy transmission will NOT bolt up without and adapter. If you change from a TH350 to a TH400 you will have to change your drive shaft yoke and the cross member. Unless you just have one lying around, or find and extremely good deal on one, there is just about no reason to put a TH400 behind a 301.
YES.
Yes.
No
yes the bell housing should bolt right up. its basically the same transmission for both vehicles, but you might check and see if the tail pieces match up. but other than that its basically the same motor and transmission for both. the z28 should have a 305 if so it would certainly bolt up. overall yes it will work. i just put a motor from a 91 sierra in an 85 camaro z28 and had no issues.
