Default Budget

I have a 1987 Corvette with a 700R4 that's motor blew not to long ago. I have a budget of about $2000. What should I do, buy a used L98 or LT1 or rebuild? Also if I buy an LT1 or 4 , or LS1, what kind of mods do I have to make in order to run perfectly on an 87? THANKS!!!!!!!

Is the budget actually $2K, or is it secretly $10K+?

If it is $2K, then buy a L31 from a wrecker or order a new
shortblock assembly. Swap over the top end from your L98,
reinstall it and go drive.

In this post, a $500 solution is suggested

In this post, a $1,142.96 solution is suggested

Observe the scope creep that takes place in both threads above.

'Top end' could mean as little as the TPI runners and plenum if
you wished.

Edelbrock offers the EDL 3817 TPI high-flo Vortec intake base to mate
the L98's TPI to the L31's Vortec heads. If you trusted that an engine
from a wrecker was in good condition, then my vote is that not much
more than intake gaskets would be necessary to prepare it.

One consideration about using the Vortec heads is fitment with the
exhaust - they have a straight plug design. Opel uses headers for
his Vortec heads, I do not know how well OEM manifolds adapt.

Depends on how it 'blew up'. I've done basic rebuilds where everything was in good shape for under $1000 easily.
