Use punctuation, pls. I read this twice wondering why in hell did you poll 98 people?

Anyway, there are about ten thousand threads on Vortec heads/engines/HP, etc. UTFSE.

Short answer is yes it is possible w/long tube headers.

The engine is a 98' right?


There is a hotrod article, and most of the time i really detest hot rod magazine, but this particular article was informative dealing with the vortec 350. i would have to look for it though, or you could.

LOL! That's exactly what I thought. But before that I read the title and wondered how he got 98 horsepower in a 350 Chevy!

How do you get 98 hp out of a 350? Fall out of bed in the morning.

I thought this was going to be some sort of aircooled VW or 2stroke snowmobile/motorcycle question...*sigh*

No, you can't mount a mechanical pump. No rod can be installed either. You're stuck with an electric fuel pump on that engine.

I've never seen a Vortec block ('96-up) that had a drilled mechanical pump cavity. That doesn't mean there aren't any- just that I've personally not seen one.

If you have a cover over the cavity, there's a chance the machining has been done. And a possibility the block is older than '96. This doesn't really mean much- if the block has the bosses, etc. to use a roller hydraulic cam, that's the main thing, not that it was a "Vortec" block.

So, if you have a block off plate and drilled passages in the block, you will need the correct pump mounting plate and a pump push rod to use the mechanical pump. Pay attention to the material the fuel pump lobe on the cam is made of (generally it will be the same as the cam core) so you use the right material for the pump push rod.

I've seen Vortec blocks that had a plate over what would have been a fuel pump location, but nothing machined underneath.
