Hey guys quick question.

I'm currently running a stock LS1 with a Paxton Novi 2000 and a cam putting 635 to the wheels. I wanted to take the next step up in power but wasn't sure on where to go.

Am I wasting my time with a 383? Should I go to a 408 or 427? I'm assuming the price range is around the 15 grand mark?

Any info would be appreciated!

What's your total budget?

If I was starting fresh with a motor blower setup, I would stay with stock cubes or maybe a ls3 block and go with a bigger blower. You are going to make more power from the bigger blower than you would with a bigger engine.

Not sure that's what I'm trying to get an idea of. I've gotten figures between 15-20k for a new motor.

Think so? Aren't I pushing my luck with a stock block? Plus I thought the Novi 2000 could reach 900hp

need a budget and goal to get a relevant answer to this question.
you run into other weaknesses before outgrowing a stock block.

I'd like to be around the 750-800 range. Guessing that will put me around the 20 grand mark.

Exactly. We have to know what you can afford to give advice.

Big fuel system, E85, smaller blower pulley, and a tune. You're there.

Sorry I misread and thought it said you had a 1500.

you dont need a 20k build for that goal, you can do that that a stock LS3.
you can also get an off the shelf forged shortblock. that's about 3500-4000 + labor

20k for what? The motor or for everything?

You are making 635rw with a blower and wanting to go up in power. The Novi 2000 blower is capable of making more power, so I would go up another 100 to 150hp using the blower to make the power. Make sure your fuel system is sized properly and see how everything works out by swapping pulleys to get to the desired range. There is no way I would spend $15k on an engine to make 800rw.

The 750 to 800 rwhp range is a great place to be with a C5 Corvette. It's a good balance of power, traction, overall control, and dollars spent.

P.S.
When you get to the 800rw mark and decide that you want to make 1000rw, take your $15k estimate and multiply it by a factor of 2.

Horsepower is expensive

/\ this basically... at the power level you are at now I wouldn't even worry about it as long as you have the fuel and the tune is spot on... you can make the goal you want on a stock block and if it breaks then you can worry about putting another motor together

I agree with this, 800-850 is going to be a damn fast car that you can also beat on without having to repair something every time you take it out
