A 3400 (3.4tdc/dohc) oil pump on a 2.8 fiero

I have a v6 fiero and my engine just took a dump I believe it was the main bearings. Going to buy a reman'd 2.8 next week from autozone for 926.00 (that's after the 250 core).

I was reading somewhere that some suggested using the 3400 oil pump instead of the melling unit because the 3.4 factory unit flows 60% more than the 2.8 factory unit. I would assume that the 3.4 pump would bolt up. My main concern was if I use this would it suck all the oil out of my pan and hurt the engine. I do drive in the 90+ range alot. I figured why pay 75 bux for a melling that has 25% increase when I could get a factory unit for 40 bux that has a 60% increase.

This has nothing to do with the 3.4LDOHC ..
I see you posted in the Pushrod section .. but why here also?

I posted here because I wanted a much broader range of answers and this is where the computer took me first when I searched. I tried to delete but it won't let me.

The 3.4 DOHC is the largest oil pump you can get. It will bolt up but I'm unsure of the pickup location in the pan. As for sucking the pan dry, the oil capacity on the DOHC is 6qt with a larger filter (PF-52) and its the same oil pan as a 3.1.

You will be fine, as its been done. Im not sure if the pickup hit anything with the newer style oil pan but I seriously doubt its an issue (bend it some to clear if anything). It does flow a hell of a lot more than stock, and is overkill if you aren't running a turbo with an oil line. I don't think its gonna hurt anything, but you will have a serious amount of oil flow on the pushrod with the DOHC oil pump. We have discussed using the SBC oil pump as well as an upgrade for the DOHC owners, though I haven't heard of anyone doing it and sharing the results yet.
