my new build
I blew my motor a year ago, and finally saved up enough money to build my motor. My car is vortech supercharged although i do have dreams of upgrading to twin turbos later on. For now i plan on upgrading to 2.87 pulley, larger intercooler, water/meth injection, headers and a new intake manifold. As far as my shortblock goes, here are the parts i plan to buy.
Eagle rods
Wiseco/CP/JE pistons (not sure what compression to get) nor what brand
ACL bearings
ARP head and main stud kit
Headgaskets (not sure what brand yet)
anything else you guys recommend me to get? what compression pistons should i get if im supercharged? however i do plan on going twin turbo in the near future.. I am also having my heads done by the machine shop. i will have pictures up as soon as i get my motor out and into the machine shop. Any feedback will be great, Here are some pics of my car currently

CCC, depending on your goals, you could skip the head work and go for a nice set of cams. From what I've read the stock heads flow pretty well. I went with the cams and i make power up past 7k rpm.

ya, i agree with getting rid of the head work. These aren't domestics so our heads aren't restrictive. You can do a lot more with that money.
I would invest that money into a good engine management or cams like everyone else said. The engine management will help you in the long run if you plan on doing turbos.
I had a 9:1 comp built engine with the vortech. I put down 451hp on injected performance DD. I ran out of fuel with my single walbro at that time.

There are a lot of conflicting messages out there about the walbro. There is at least one dyno of a ttZ making north of 500whp on a single walbro. If you want more flow than the 255lph, you can always get a KB Boost a pump. Although I'd suggest getting a new 340lph pump first.

Injected performance DD dyno is notoriously low. That same number corrected similar to a DJ dyno would be about 507hp.
You also have to understand that a supercharger has about 20% parasitic drag on the engine so you can expect to use quite a bit more fuel to produce the same power.
Also on top of that you have product variance. If there is a 10% variation in the pumps being produced then that makes quite the difference in power output each pump could handle. They aren't all exactly equal.

thanks for the info guys! what do you guys think about headers and a new intake manifold? my goal is 500 whp, i know thats probably a long shot ... but thats why its a goal lol. if i get past 450whp i will be happy.

twin turbo cars with high quality injectors will make quite a bit from a single walbro. supercharged cars seem to run out in the mid to high 400s. so i agree with binder, the SC appears to soak up roughly 20% of the engines power.
