use your pre 87 unless you have rollers or the application calls for +5 or other.
vortecs have rollers.
Take off valve covers, heads an intake manifold with throttle body, pull out lifters and pushrods and simply replace It's not necessary to remove the heads for this procedure.
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
no the heads are diffrent
That's what should be on it.
chevy didn't come ouy with vortec heads until the 90's . I'm thinking about 96, so just because they are centerbolt head doesn't mean they are vortec. sorry pal
no they will not
No not even close.
No, but if the 96 has the 5.7 Vortec engine then it will have different heads which give it more power. ETA Question: Can I put the '96 vortec heads and intake on the '93 engine? You will need a vortec specific manifold. Edelbrock makes one
Start in the middle and go in a circle
No. Not without switching the cylinder heads. I think it was 89, Chevy came out with the 1st generation Vortec heads, which require a different intake.
The word 'vortec' is the name of the cylinder heads used in Vortec Model engines in the year 96'+ The engines that use the Vortec cylinder heads are the 4.3L Vortec, 5.0L Vortec, 5.7L Vortec, and 8.1L Vortec. They were only put on Gen I small blocks. If they are any other size Chevy engines and still retain the Vortec name then it's purely a marketing name, the same goes is it is later than a Gen I engine. For example the new 4.2L I6 from GM retains the name Vortec, but it does not actually use Vortec heads as these heads were only made for OHV engines, and the I6 is an OHC engine. The Vortec heads are based on the LT1 and LT4 head after they were discontinued along with their reverse flow cooling design. It is simply an effect made in the head similar to a vortex to better atomize the fuel and air intake charge when entering the combustion chamber, it is not a different type of motor.
You will need an after market Vortec Intake None FI 4BRL set up. The vortec engine has longer runners to increase air speed for the vorteciy action of the heads.
