Can a 1987-92 GM tuned port injection system be used?
Can a 1987-92 GM tuned port injection system be used?
When using the 1987-92 F-Body injection systems, the two center bolts on each side will not fit the earlier engines without being re-drilled for the proper angle to match the early heads. Also 1985-88 manifold plenums have a cold-start passage and ninth injector for start-up.
What kind of head does a 1985 Corvette have?
Also, the earlier F-bodies (1985 and 1986 305-cu.in.) and the Corvettes using cast-iron heads have the same bolt pattern as the earlier small-block Chevys from the 1950s through the 1980s.
When did the Chevrolet 305 V8 engine come out?
As America faced an energy crisis and the government began to regulate a car’s emissions, General Motors made adjustments to many of their small block, V8 engines. GM introduced the Chevrolet 305 engine in 1976 to provide a smooth driving performance while allowing for lower octane fuels and lower emissions.
Can a 305 cylinder head be ported into a water jacket?
These heads will port out well, but be aware that 305 heads have smaller valves, so only look for 350 heads unless you’re specifically working on a 305. This will save you the expense of extra machining to put in larger valves. Also, if the porting technician is too exuberant, there’s the possibility of porting these into the water jacket.

What kind of fuel injection does a corvette use?
For 1985, Chevrolet replaced the Cross-Fire system with a new Tuned-Port Injection (TPI), a fancy way of saying port type fuel injection, on the Corvette’s 5.7 liter V8 thus changing the RPO code to L98.
