yes, just need to change the fuel cross over line cause it wont fit
Yes they are the same.
no such thing as a vortec 5.3 tbi
It will as long as the 305 is a VORTEC ENGINE TOO.
No it will not, Totaley different.
yes they will fit, but you will need an intake manifold compatible with vortec heads if you plan on reusing the carburetor
The heads will fit the block, but the vortec intake manifold will not bolt to the old style heads.
yes
will 1995 Chevrolet 350 intake fit a 1997 vortec heads
Yes, they will fit, and increase torque by a good amount. However, the Vortec heads used a vertical intake bolt design, so you will not be able to use your intake manifold. Side note on the vertical intake bolts, you also need to get Vortec specific intake bolts, because they bottom out in the heads to stop from overtightening and seal better. All in all, vortecs are a good purchase, if you have the money for a new intake manifold. Edelbrock makes some great ones specifically for vortec heads on older engines. look into it. hope i could help.
NO, Not even close.
No, a 5.7 spider intake manifold is not directly compatible with a 5.3 Vortec engine due to differences in design and bolt patterns. The 5.3 Vortec typically has a different intake port shape and alignment compared to the 5.7. However, with modifications and the right adapter plates, it may be possible to make them work together, but it's not a straightforward swap. Always consult an expert or do thorough research before proceeding with such modifications.
No, a throttle body intake from a 1993 Chevrolet 350 will not fit directly onto a 1999 7.4L Vortec block. The 7.4L Vortec has a different bolt pattern and design, as it is part of a different engine family with a more advanced intake manifold system. Additionally, the Vortec engines typically use a different style of fuel injection and require specific intake manifolds designed for their configuration. Thus, modifications or an adapter may be necessary for compatibility.
