What are you working on?
2 main areas to start. Intake and exhaust. Every time. From there you can do internals but an engine is really an air pump. More in, more out. Until they are made to be efficient you will be wasting your money.
From there you can do cams, heads (port and polish/valves) or power adders (nitrous/turbos/super chargers). The sky is the limit. Keep in mind two things; It costs a lot to go fast, and Speed is addictive.
Good luck!

TSgt David L. - I'm an auto-newb but I'll look this stuff up in the near future after I start working.

PO1 John Miller - I don't know what you are talking about. I'm still trying to check my oil. Then I need to figure out "what kind of oil I need to get"! LMAO :p

I use HP Tuners to tune my truck; I have a GMC Sierra with a turbo. This tuner can do a ton of things to your vehicle.

SGT (Join to see) - I cannot abide refilling tanks - so no nitrous for me. The first and most important part is to get a thoroughly experienced wrench head on board - by whatever means is necessary. Then a Chevy big block crate engine (or LS if you are rebuilding a rice box), positive displacement supercharger or turbo intercooler - cold "heavy air" intake system. Hack the engine electronics for precision instrumentation and to optimize power output control systems. Fuel injection, increased head space, cold forged, annealed & anodized high lift steel crank shaft, rods, pistons, inconel valves and copper-beryllium valve seats, racing suspension, racing breaks, racing tires, and a pretty radical complex electronically animated undercarriage lighting system. Precision traffic, radar, laser, red light, and bear sensing NAV COM intercept / jammer with the latest possible generation GPS. That's about it for stock parts - then you can get into a bit more exotic parts and fuels for more performance. Warmest Regards, Sandy :)
p.s. Just thinking back to my old pursuit driver boyfriend. I rock a far more traditional ride now.

You funny, 1LT Sandy Annala. "Stock parts" my arse! LMAO
Nice Vette! Yours? I'm jealous. I have a 454ci with a Whipple Charger in my Suburban, so I'm in agreement with your post. No replacement for displacement, as they say! Not much for turbos personally, but they are a viable option. I'm not worried about parasitic drag with nearly 500hp!
It's a little trickier to up-tune an engine with positive induction since you can't get away with adding timing, and compression needs to be down compared to a built, naturally aspirated engine. BUT, there are gains to be made through mapping the AFR and timing curve and other tuning.
Nice to have a gear head chime in!

TSgt David L. - That was my partner's gift for private weekend drives out of town and/or in the countryside. The agency light armor suburban is larger and slower - though it can manouver pretty well and move quickly when need arises. Warmest Regards, Sandy :)
