The big difference with a vortec vs normal gm motors is vortec has different head design and the intake manifold have bigger runners. In 1995 vortec heads still used T.B.I injection with the top end of the engine being vortec head and intake mainfold.
The 1995 350 or 5.7L has a T.B.I. and standard heads. 1996 its a C.P.I. and Vortec heads.
Yes.
the vortec block and heads were introduced in late 1995 but actual vortec motor started coming in vehicles in 1996
A 1995 Chevrolet Tahoe has a 5.7L 350 TBI V8 for a engine, not a vortec.
This is what you will need. Vortec Heads,Intake,distributor,front timing cover,crankshaft sensor and 60 to 66 LB. fuel pump Ect.. If you are talking about putting a vortec engine in a 95 then you will need alot more. Let me know what you are wanting to do and I'll help you.
Apparently, there is none. They started using them in 1996.
what type of motor is currently in the tahoe? a 5.7?
The valve is at the front of the engine just behind the A/C Compressor. Its just above the thermostat. Be careful as for some unknown reason GM has designed this valve without polarity. It can be installed upside down which will yield less than impressive results. Where is the EGR valve located on a 1995 Chevrolet Blazer with a vortec engine?
No it will not. Those 2 engines have a total different type of fuel system and sensors.
no, the bolt pattern on the small block Chevy intake manifold changed in '87 to the vortec head design, but if it doesnt have the centerbolt valve covers, then it will.
http://www.customclassictrucks.com/techarticles/0405cct_vortec_cylinder_heads_small_block_chevy/index.html This will answer all your questions. Yes it can be done. There's a bit more to it than just torquing on a new set of heads, but if you can replace heads, you can more than handle the rest of it. Should flow much better than the stock TBI heads. Vortec heads flow far better!
