And that's the part so few people hear when they read build threads on the internet...

Yah, nobody checks the dates... lol

My Z24's 3500 swap, began in Summer 2006 with the removal of a blown up 3400, Engine first fire 5/5/2007, first drive 5/10/2007 and then a year or so of tuning to get it right, set some dyno and track records and have a ton of fun.

Putting previous 3500 in the '89 Camaro, Project actually started (planning stages) a few months before this post was made, around June 2009. Engine first fire on 11/12/2010, running/driving April 2011.




I kind of miss spending every night in the garage working on those cars, but with 2 young kids it's kind of hard. Won't be long before things get rolling with my Nova though.

I can get an engine for 2-300 bucks. A chassis for 600-1000 bucks. I am going to do things bit by bit but i still think that a good cam can be obtained for under 200 bucks

[SwiftDrift]

Oh and quick question, without a tb how large is the opening on the 3400 plenum? Is it 65mm?

[Superdave]

Keep watching the for sale threads on here, you might find a good deal on a roller cam.

and roughly 56mm

[caffeine]

All the little things like fuel lines, rad hoses, exhaust, fuel injectors, ECM, memcal adapter, flywheel, etc... add up quickly. Which is why I think you should budget at least $1000 to get the engine in.

[SwiftDrift]

Anything i have talked about is going to slowly happen over time. I just need to decide where to start after i have the car. I plan on getting that 2.8 out as soon as possible. But i wanted to have at least a cam in the engine before it goes into the car.

[SwiftDrift]

When throwing in a mean cam, what limit would come first: flow or injectors?

[caffeine]

Probably injector

[SwiftDrift]

what are the lbs of the stockies?

[caffeine]

24 lb but if you use the stock injectors/fuel rail you will need an external fuel pressure regulator. Cheap way to go is a 00ish corvette fuel filter which has a built in regulator.

Otherwise most people use 3400 rails/injectors which are around 19-22# depending on year.

[SwiftDrift]

Do u think i could even make it over 250hp with injectors a cam and tune? I wont be able to do anything crazy until i move.

[caffeine]

Probably

[SwiftDrift]

If done right, what would u say i could get?

[diabolical1]

Most 3500/5 speed Jbodies are putting down a little over 200 WHP, One that I can recall with a set of WOT's headers made around 215WHP but with some other upgrades like a good exhaust and intake he'd probably be a little higher. That's around 235HP @ the crank. 34hp more than stock application/tune.

In your opinion, what would you think one could get out of an LX9 (without headers) in an Impala? I figured I'd search and ask in a related thread before starting my own.

I set a soft goal of 230-240 HP (flywheel) and I want to see what I would need to get there. At the moment, I'm running the engine with LA1 upper intake, but I have the LX9 upper, a 65mm throttle, some injectors and I do plan on opening up the exhaust a bit. If I can find decent headers (that fit the Impala), then I would be game to install them, too. I plan to top it off with an Overkill PCM. I would entertain the thought of a mild cam in the distant future, but for now I have no plans for one. At the end of the day, I just want some more pep, but I have limits. The car's main function is still just transportation, not performance or racing so I want to keep it as simple as possible (no porting, pistons, etc.). I don't want to screw with the idle or fuel economy too much, if at all.

Probably

So in your opinion it 230-240 (without the cam) should be within reason? Would that apply to an Impala chassis, too or just the aforementioned J-bodies?

[Superdave]

put on the LX9 plenum with that 65mm TB then put in a cam. You'll hit your goal without any porting needed. Headers will of course help.
