Will an LT1 intake and fuelrails from a 1994-1997 LT1 fit my 1993 LT1? I know the fuel rails on my '03 are different. I found a set of heads, intake, and fuel rails for $300. I'm considering this versus reparing my heads which are a wreck, the weather got to them after a blown head gasket.

 

As long as you keep the fuel rails with the intake manifold (93 on 93; 94-97 on 94-97) the intakes will bolt to any LT1 heads. The fuel connections (supply and return) will be in a different location though.

The question that comes up, and I don't know the answer - how do the 94-97 rails respond to the 93's batch fire injection, rather than the sequential injection they were designed for?

 

I swapped a '94+ manifold onto my '93 and kept the '93 fuel rails. All you have to do is take the cross-over tubes from the '94 rails and bolt them into the '93 rails (the widths are different between the two styles). I think I had to slightly file the mounting holes to get the fit just right, but it went together really easily. That way, all your fuel line connections will line up and you won't have to worry about eliminating the accumulator.
