which intake do i need for 89 vette?
I have an 89 corvette and am getting a zz4 here in a few weeks and need to know which intake i am supposed to get. I am wanting the edelbrock hi flow tpi runner/base kit, but dont know which one to order cause they have a bunch of different versions of it.

one says for 85-88 engines and the other one says 89-92 engines, but both of them say for 85-91 corvette? So which one do i need to get?

I just looked up the intakes you have listed on other sites and they are just as confusing as the ones on Jegs. I always thought that the Edelbrock #3891 set was the one to use, but now I have no idea..My suggestion is contact Edelbrock directly by phone and ask them which one will work..If they don't know who would...WW
Here is there phone (# 1-800-416-8628 ) get back to us and let us know what one they say to use..

It is all based upon if you have the 9th injector (cold start valve). I believe in 1987, they wnet with the second generation intake bolt angles (center bolt valve covers are an easy aide to verify this).

I just called Edelbrock from the number that WW7 posted, and the technician said, to order part number #350-3891 which will fit the stock 89 TPI Vette or the ZZ4.
The tech also, said part #350-3893 is for use with aftermarket heads only.
I typed in part #350-3891 on both the Summit and Jeg's websites and they are both available for $745. Summit will ship out today, Jegs will ship out in 11-18 days.

Not to throw a wrench in the works, but is a TPI intake a good match for the ZZ4? It will probably work, and I don't know anything about the ZZ4, but if it is a high RPM engine, then wouldn't putting a TPI intake on top of it limit it's potential?

I asked this question a few weeks ago because I also am getting a ZZ4 engine very soon. The response from most was get either the Miniram or a First intake, but from what I have read the Miniram will give better high end power but at the expense of low end torque.As far as the First intake I have tried going to there site for 3 weeks now and have not been able to connect. Hope they haven't gone bye bye. I have also been told to get a high flow base, SLP runners, and have Mike at Corvette Plenums mega port the plenum and siemese the runners, have the base ported and then I will have enough air flow plus I would increase the low end torque.What I am trying to do is keep the ZZ4 as close to the claimed 355 hp as I can..At this point I am still doing research and haven't made up my mind yet....WW

The engines are almost identical, but for the slightly larger camshaft in the ZZ4. ZZ4 is rated with a carb and open exhaust, if they had put a TPI on it with stock manifolds the power wouldnt be too much higher than a '91 makes. Ballpark difference of 10-20hp.
