The Direct Bolt-In Replacement Throttle Body Injection Engine Is Smog-Legal For 1987-95 GMC & Chevy Pickups, Suburbans & Blazers

Does your 1987-95 Chevy or GMC TBI truck lack the power to tow up steep hills? Does it seem like it takes forever to get up to speed even on flat land when you’ve got the trailer in tow? Does it just seem tired in general?

The throttle body injection engine that came in Chevrolet and GMC pickups, Suburbans and Blazers produced just 190 net horsepower stock. Smeding Performance’s 383 replacement stroker motor produces 310 hp at 4,200 rpm and 420 lb-ft of torque at 3,300 rpm when installed with an upgraded exhaust system and computer chip. That extra 120 horsepower means you’ll see dramatic improvements in towing abilities and around-town performance. Plus, all of the stock TBI components bolt right onto Smeding’s crate engine—no modifications are necessary. It even smog-legal.

This Smeding crate engine is not a rebuild. The TBI stroker long-block starts out with a brand-new GM 350 4-bolt-main block. This block is modified to accept a new nodular iron crankshaft and steel connecting rods. The rotating assembly is spin balanced to within 1 gram to assure smooth operation and longer engine life. A hypereutectic, moly-graphite-coated piston is used, along with moly rings, to assure a better combustion seal and virtually no piston scuffing. The ProAction cylinder heads are machined to match the flow characteristics of the smog-legal camshaft. The Smeding engine is assembled with a new double roller timing gear set, Melling oil pump, Fel-Pro gaskets and an Edelbrock Performer intake manifold.

Smeding’s 383 crate engine is perfect for truck owners who want more power without sacrificing durability. Smeding sells the Chevy Stroker 383 TBI for $3,995. It comes with a standard two-year limited warranty.

Smeding Performance specializes in building reliable, low-maintenance crate engines for truck, car and marine applications.
