Need advice on what to do...
I have been back and forth on what to do with my car for some time now. I had several purchases go sideways on me which regrettably really set me back timewise also. I was going Maggie/A&A or 402.
Here is my current situation. The maggie is out- off the table. So I have 3 options right now... A&A V3-Si, or new fresh fully forged 402 with all the best components money can buy should easily lay down well over 500 rwhp, or just leave the dam car as is and go on vacation lol...
The engine will by far cost me the most money but is built to take whatever boost I can throw at it which means NOS right now or super charger later on and it will be a serious power car. Blower right now will be on a bone stock LS6 which means low boost until I decide to forge a motor. What would you do and why if you were in my position? The car will see some track use but just want the jam to have a little fun.
What would a fully forged 500+rwhp 402 cost ready to go with heads/cam etc?

I'd boost the stocker. With the right tune should be safe for a good while.
A sprayed motor and a boosted motor need different components to maximize the build (pistons, heads, cam). Compression ratio will be (should be ) different. It could be as simple as changing heads and cam out when you are ready to boost but it seems nothing is ever simple, or cheap.
Depending on the vendor a fully forged shortblock may run around 5k on up. Mine without heads was 7 and after the install (and fuel system) and all it was around 12... Dang this is really making me think about it now LOL. Any specific questions I'd love to try and answer although I can only go off my build
Good Luck!!!

If you go with the 402 option, and go for maximum performance, it'll have alot of components you'll need to change for going with boost later. The most difficult item would be your compression ratio. These motors love high comp. if NA.

My question to you is: do you really know what you are getting
into???? If you start modding your vette it will never stop. You
would be better off staying stock and retain more value.
But if this particular vette is your baby. You love it and never
sell it as well as have moded other cars and know what to expect
go right ahead.
If you get the sickness your best bang for buck is FI.
Just remember that when you start it will be hard to stop.
You have been warned.!!!!!!!!!!!!

Without a doubt, go all motor. Once you have a rock solid platform to work with, you can always go FI later down the road. Higher compression does not mean you cant run a supercharger. And if you did have a need to run lower compression swapping out the heads for some larger chambers is a small job.

Vacation?? Are you kidding?? This is the F/I section. Not the detail section. 
All kidding aside, I couldn't enjoy a vacation knowing I was going home to a stock car that would be stock for a long time. N/A is fun. Supercharged is more fun to me. Even if I ended up with the same #'s, I would rather have a supercharger.

02 Z06 with a blower,
A 402 that makes similar power, will chop hard, stink from the cam overlap, and cost about 10G's.
When you want to do a blower on top of that, you gotta, ditch the heads and lower the CR and do the fuel system-before you even consider slapping a blower on.

I think the real question is what kind of power are you looking to make and what do you plan to use the car for? Before you start talking about more cubes, give us that info. From the sound of things, you'd be happy with 500whp and you can do that + much much more on stock cubes.

A&A kit iam sure will come on sale in christmas time, bite it than. Looks like we both are in same situation, except i lost the zest in extra power, too many personal problems.
2 months ago i had partial maggie, H/C complete package, and nitrous, well now nitrous kit, maggie and heads gone, only thing remains is a cam package.
Pretty much iam done, with mods.
My vote goes to andy's kit, if not go for sleeper cam/head package (small cam with AFR heads).
Edit: mike when u do polish with polisher lemme know, i would like to learn that thing. If u cant go fast make it a show car..lol.

The way I see it: Access to a 402 right now at $0.60 on the dollar for the build will end up running me a solid $12K+ installed. A&A Kit shave $5K off the 402 price but my options are fixed at this point power wise. This leaves me with only 1 real answer....win the 40 million dollar jackpot tomorrow night and build 3 or 4 of each combination.
My 383 stroker from 8 years ago in my first vette. This was my first mistake lol... The first of many.

Well seeing how you have one of the best tuner (Arun) in the world in your back yard it's a no brainer. I would buy a YSI and grow into it. You are already talking about a 402. Buy the big blower now and spend a few hundred dollars more and not have to sell the smaller one to buy the bigger one later. Boost is addicting and NOS is good bang for buck but it's a bigger head ache IMO.

Hi Mike, you gotta decide where you want to be in a fiew years and you need to decide your total budget...or decide what ET and mph you want to run, and take it from there. Arun and Rob will lead you in the right direction If you want a 9 second ride, it will easily cost between 20-30 grand all said and done, if you want it to be reliable, and have some of the good stuff..ie Lonnie twin pumper, a twin clutch or triple clutch, motor, blower, suspension, drag pack etc..if you do it right the first time you wont have big big downtime....and you will save more coin in the long run. Best of luck with your build...I have purchased some used stuff and have been lucky, and pu a lot of parts at the border myself and saved big time....I dont reccomend you building a monster though, cause you "may" have a heavy foot eh
