Default Engine Upgrade

Hello
I have a new chevy 350/290
hooker black headers
600 holly
2101 edelbrock intake
flowmaster super 44
I add a L88 hood scoop
77
auto 350 turbo
stock rear but plan to change it to 3.73
I am planing to change it to 5 or 6 speed in the future.

My plan is to add more H.P abut 460+
After doing the engine there will be a plan to supercharge it or Turbo.

So I want it to handle a good amount of above 460+

I am thinking of Vortech 4GP218-050L

http://www.jegs.com/i/Vortech/933/4G...SABEgIievD_BwE

Planing to use the vette 3 days a week

Budget $2000 on engine parts I can go a little more if its necessary

I am open for all suggestions even if it takes me to change the hole engine
Thanks

what year? what transmission is behind it and in what condition ? you may be about to exceed its capability ..remember big power has to be transferred to the wheels.

So you want 460+ HP from a 350/290 HP SB for 1600 dollars? Never going to happen. First off those heads will never flow enough for that kind of power. The bottom end of the motor will not take that much power for very long either. The 350/290 motor is pretty much a base motor. You mention a 2100 super charger and only want to put 1600 into the motor? Also with that kind of power the transmission and rear end and half shafts will all need to be upgraded. Just saying for anything approaching the 500 HP level you better have a much bigger budget.

Thank You I loved it when you said never going to happen . I did edit it to $2000. From your words I feel it's impossible?
So in a budget of $4200 or a little more will not bring me an engine that can have almost 500 H.P

Bust open that wallet.....think $6000 minimum (and only if can find some real deals on parts). This link is to a typical crate engine, less than 500 HP just to give you an idea what it costs........

I can't guarantee 460hp, but I can suggest a build for your budget that will get close.

Your big hiccup is your heads. They will not flow enough to satisfy the thirst of 460+boost. If you are going to turbo, you will need to find better low compression heads. Check C-List for a pair of procomp or similar china heads and pay $500. Go buy your self a new cam and lifter kit from Lunati, Comp, Herbert etc... $300. Buy your self a GOOD eagle balanced rotating assembly for about $1200. Should have some forged internals. Finally, buy the gasket set for the whole motor.

Pull your engine, strip it down, Take the block in to have honed and prepped ($160). Begin assembly.

RING GAP!!! Make sure you gap your rings to handle boosted applications. Last thing you should do is boost a motor with out of the box gapped rings. (Good bye cylinders!)

You will have a 400+ motor that will handle moderate amount of boost.

The key to any budget build is knowing where you are going, being patient, and pouncing on the opportunities of second hand when they come about.

Edit: If you don't know anything about heads or what to look for, you should start educating yourself on them. Always get a machine shop to look them over if possible. If the person claims they have low miles and are ready to bolt on, they won't have any issues with you meeting them at a machine shop for verification of what they say to be true.

Best of luck

you should consider just going to a good crate engine with your desired power range... with a warranty... matching components exactly is key to power and more importantly driveability .. with a crate , its already a tested combo

FWIW, I think centrifugal charger would be a better route to take over turbo. Plumbing for a turbo on a C3 is a bit of a challenge with space being so limited. Plus, being a casual driver on the street, charger would be more fun at that type of driving.

Thank you
But can you compare the blueprint one it's more H.P and a lower budget.

Go for it.....good deal, but remember the Summit Blueprint one is a long block, not turnkey, and you'll have to add for intake, carb, ignition, and proper tuning to get the advertised HP.

My Vortec build required a blow through carb. At the time from CSU it ran a G-note. A new fuel delivery system is required. High volume pump at low pressure, a pressure regulator that increases pressure as boost increases and an ignition system that retards timing as boost goes up. Your engine should have a cam designed for a boosted engine. And then when you get every thing sorted out with the engine running right, the hood wont close. A blower engine needs a good solid foundation, engine, machine work, and heads $4000 t0 $6000, upgrade to super charger $6000 to $8000. I have only found 5 C3s that have centrifical chargers on them. Sure you'll be able to snap the tires loose at 40 mph in 2nd, but those stock drive line parts will be laying on the ground so lets beef up the IRS to handle that, lets say $5 to $6 grand. My advice is to stick with a carbed engine around 450 to 500 hp max and have fun. T

Can't go wrong with new Vortech. I think that is a safe setup too, but you would be able to run more boost with the budget build I mentioned. Maybe if you get down the road, you find a v-2 charger on C-List used, spend a little less than that and get 8-10psi.

Might want to start thinking about your drive train if you are going to be doing hard launches...

There's a Virginia Chevy dealer sells brand new crate engines for 1700 bucks. Yes these are standard lopo crate engines. But you start with them change the cam get a set of heads. You're way ahead of $6,000.
