Not hard with the proper tools and equipment. A shop repair manual would be helpful.
Yes and no. There is an issue with the radiator being too close to the fan. Otherwise, it is a rather simple swap.
Body panels- 1989-2006, 1989-1998 geo/chevy tracker
yes but the cpi injection in 1998 is way different than chevy's 1993 throttle body system so the whole computer system must be adapted or swapped and the heads are different so you cannot just swap the intakes.
Not hard same block just have to have a 1987 or new heads
If they are both 3100 engines...yes. Direct swap. The only thing you MAY have to change would be the motor mounts.
the 95 and the 93 full size pick ups are identical there should be no need to swap parts the 95 vortec from an S-10 will need the entire intake manifold, exhaust, sensors, and wiring harness from the 93 to make it run
Very hard. You will need to swap transmissions, drill holes in the floor for the clutch cable and pedal, etc. You're better off trading the car in on one already with an automatic.
NO.
Yes they are the same block and heads you might have to swap intakes though
1964 to 1987 El Caminos swap to their A-Body sister cars and vice versa
Fairly straight forward. No engine swap is easy, but they are both small block Chevy's and it will not be that difficult. The Chevy 305 and 350 are the same block just bored out different. they aren't that hard to swap it normally takes about 6 hours if you have all the right tools and a buddy to help just remember where all the bolts came from and if its a manual its best to change the clutch now while its out now!
If the cubic inch is the same the motors should swap out ok. You will have to change some parts but most Chevy motors will swap.
