Will an intake manifold from an older 350 fit on a 350 with vortec heads?
No it will not, Totaley different.
Will the heads off a 97 vortec fit of a 88 350 block?
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.
Will 89 Chevy tbi manifold adapt to older small block?
Yes, however, in 89, Chevy started to update the small block, and came out with the SB2, or first gen., Vortec, and redesigned the cylinder heads. One of the changes they finally made was to change the head angle, in relation to the block deck. This also changed the intake manifold/cylinder head, relationship, making this intake non interchangable, with the SB1, or the standard heads.
Will 68-79 heads work on a vortec 5700 block?
They will bolt to the block but the intake will not bolt up. The vortec heads have raised runners so the ports would not match. You would also be decreasing performance as the older heads will not flow like the vortecs do or have as good as a flame travel due to the vortecs heart shape chamber,.
Would you get more horsepower out of your 1986 Chevy 350 if you changed the heads to vortex heads or older model 350 heads with a 3 angle cut and milled?
vortec heads will give you more power than any stock older heads but require a different intake and have small combustion chambers so make sure you dont get your cr to high and check for valves hitting the piston
Can you use a 1988 block and heads on your 1997 gmc 1500?
Yes but the four center (two on each side) intake manifold bolts will need to be elongated as the older heads had the the holes at and angle and the newer go straight down.
On a 1981 cutlass 305 intake manifold is it possible to change with a 350 intake manifold?
the manifolds should be the same for the 350and 305. be careful, however about the year of your manifold, older manifolds have the four center holes drilled at the same angle as the heads and the rest of the holes, newer manifolds have the four holes drilled straight up and down, and the two are not interchangeable
Will 1979 Chevy 350 heads work on 1992 Chevy 350?
You would also have to change the intake manifold, with the heads. I feel compelled to advise you, you are going backwards in technology, thus less performance, and mileage. The newer heads flow better. However, I understand the need to get on the road cheaply, so if you use the older intake, yeah, you could do it.
Will regular 305 heads fit a 350 Vortec engine?
No 305 heads bolt up different then 350 heads If they are 305 vortec they will bolt up. However they do not have the same flow. The 305 vortec head has smaller runners, smaller valves and does not have the same heart shape combustion chamber. Now if you meant the older 305 heads onto a 350 vortce then no they will not. The vortec uses raised runners and the ports will not match. On top of it all the 5.7 vortec has more flow then any other production head. Placing a 305 head in its place would be going backwards.
Can you take an older 350 and put it in a newer vehicle?
To give a good answer to this question it would be necessary to have the year of the engine and vehicle. In general ( again depending on the years ) the blocks haven't changed much but you may have to get different heads and an intake manifold for it.
Why does 3800 engine intake manifold water leak?
In my Chevy 1500 with the 305 Vortec, the problem was the lower intake manifold gasket, which is the one that seals it to the engine block. On your 3800 V6 (in a Silverado? I didn't know that; I thought it was the 4.3, maybe it's an older or newer year than my body style), it could very well be the same. There is also a coolant line coming out of the manifold, if I'm not mistaken. Could be to the thermostat, but I don't have the truck anymore. To the best of my knowledge, that would be the easiest and cheapest thing to check.
Will a 1998 vorteX 350 motors' intake manifold fit a older chevrolet 350 motor?
NO, Not even close.
