with aftermarket cams the engines power band is moved slightly higher with each "stage", by rough they mean the engine is wanting to be higher in the RPMs but can't. for tuning its mechanical and i don't think you can smooth the idle, i may be wrong though.
also on the crower brand it doesnt say it needs lower gears but on the crane brand it says lower gears required.

all the gears do is to help get the engine into its new power band sooner
and what can those springs do
aftermarket springs have more pressure to close the valves faster to prevent valve "float" which will cause SEVERE damage if not used
and as far as the cylinder heads go. it talks about the 5.4 in the description but it only talks about the 4.6 in the applications.

both are "modular" motors, block/heads/cams/cranks, all can be interchanged

so in other words if im going to do one of those upgrades i might as well do all of them. How much extra power do you think i can get with the extra tuning. It says around 100 HP with out the tuning.

if your gonna do it, may as well be right the first time.
most of the HP claims assume ported heads/valves, on stock heads a more realistic number is ~70HP. also, most claims are not "peak" gains.

Seriously.
The best bang for your buck would be a supercharger.

Neither do I!

[martinoledad]

my goal is to get as much power without losing gas mileage.

[martinoledad]

How much of a performance gain can i get with premium forged pistons like these

Keith Black/KB Pistons IC884KTD-020 - Keith Black ICON Premium Forged Piston and Ring Kits - Overview - SummitRacing.com

Will there be a MPG lose with something like these.

Or is there a better brand, i dont know much about pistons and stuff like this

[88Racing]

If you're planning on splitting the block then go all forged internals with a supercharger. The pistons alone aren't going to help much by themselves.

Or.....
Call it good and buy yourself some of these.

Just a thought........

Would you be paying someone to install these pistons, cams or other internal parts your asking about?
