I am thinking of going this route, but I want to know how it will benefit me the most.

Which should be first, a new rearend or forged engine components?

Colonel

The best reason to use forged pistions is if you plan to use nitrous or forced induction. They are more resistant to detonation and high temperatures.

So would a car with just stage II heads and cam ever really need to upgrade?

ive heard of people pushing the stock bottom end to 450+hp and running 6800rpm, so with just thoes heads i would get the rearend first

So you can put a 200 shot through it and sleep at night! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

oil pump and rod bolts are all you need to upgrade for high rpms. Forged pistons are only needed for nitrous or FI like colonel said.

Does anyone make an inexpensive, hypereutectic or cast piston for a 3.905" bore? I'm close to doing a rebuild and don't have a lot of money to throw around. The engine's got 53K miles and it doesn't smoke so the rings are probably ok. Probably just needs a cleanup hone.

Or you can go with Forged JE's or Diamond's. That's $600, plus you might as well spring for good rings.

That's why I love this place. You guys ROCK! <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> <img border="0" alt="[pimp]" title="" src="graemlins/gr_pimp.gif" />

In fact, if you are looking at high RPM NA engines, I'd suggest not using forged pistons. They are a bit heavier than hypereutectic pistons and tend to be a little rougher on the block due to their tendency to swell a little until they are warm. Hypers don't expand as much, so you can run tighter clearences which helps with oil consumption and compression.

JackZ28

Are the hypers the stockers?

Colonel

Yes.

get nice rod bolts.
Because then the stock internals, hypereutectic pistons really will make a mess if a rod bolt lets go.

Track officials found many of my piston bits around the 1000 ft mark. Just a heads/cam too, redline at 6700 ;-)

Forged will expand and contract more than hypereutectic.

Did he say the forged pistons are heavier than stock?

JackZ28

Yes, that is what he said. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

You learn something new everyday. Maybe that is another reason why my horsepower #'s are down.. NOT!!!

How heavy are the stock units? If you have a well made Forged Piston it should be much lighter than the stock unit.

He does upgrade the bottom end with the 650 TT package.
