Engine Woes

zach0 · 05-06-2002, 03:52 PM

Alright, so I'm indecisive. I am now looking between three different combos. 1. Ford has the 345 horse 302 or a Ford 302 or 347 short block with the Holley System 2 setup. I want to get as much horsepower as I can but I am not sure on the Holley setup. I want to add a Vortech charger in a year or so on this engine. If anyone has used the Holley Syetem setup let me know how it was. This would be going in place of the 289.

I can't help you with the Holley question, but if you're planning on adding boost, I'd stay away from a 347.

Take care,

Why is that?

Ummmm, what would you be doing the 289 that is coming out? If you decide on selling it, I'd be interested in knowing more info on the block. Thanks!

Well, the 347 stroker was never designed to last for more than 5k miles. Only recently have parts (rings/pistons) been redesigned for it that give it a chance at reaching 50k miles safely. Adding boost to an engine that has been maxxed out as much as the 347 has is just asking for trouble. For a race-only car, go for it. But, for a daily driver, I wouldn't. No way. I'm not even real comfortable with the idea of adding boost to a 331 stroker, let alone a 347. As long as the parts used were top of the line, a 331 would be okay with a max of 8-10 pounds of boost (10-12 if intercooled). Still, you're jeopardizing your ride with alot of boost. A stroked engine adds alot more load on the main journals all by itself. A boosted stroked engine adds ALOT more load. The 302 block isn't really that strong to begin with.

If you've got the money to build it right, and that's what you want, go for it. For me, I could get equal performance with better reliability for the same money elsewhere, but that's just me.

Take care,
-Chris
