As soon as it warms up here . I am going to do the same thing to my 1989 5.7 TBI Truck . Yes you can use that 1987 350 one-piece seal Long block with a carb set up . The Difference with the 1987 and newer SB Chevys is . The two center bolts for the intake are at a 72 Degree angle . Un-like the earlier SBs that were at the 90 Degree angle . You can use the early intakes on the 1987 and newer engines by elongating the center 4 holes of the intake manifold . You will also need to use some grade 8 washers for the holes . I do not like to do this . But if on a budget and you have an early intake it can be done . There are some intakes out there for this swap . The cheapest one is the . Professional Products Cyclone dual plane intake . It come with special adapter bushings to fit the 87-95 engines . It also will work on the older engines . The part # is 52001 and it cost $115.00 bucks . Edelbrock and Holley makes intakes for 87-95 SBs but they are more costly . One more thing is you will have to run an Electric fuel pump . The 87-95 blocks were not drilled for the mechanical fuel pump rod . And a HEI 1980 or older . COOL
