Opinions/real world experience wanted: LS swap or L98 build

Yes, anything is possible in the grand scheme of things. Your Snap On or Craftsman tool could break before a cheap Chinese POS. Mercedes has made their own share of lemons. OTOH, a Yugo is probably more likely to have a lemon than an MB. The odds are not even which is why it is cheaper. I can get a virgin 5.3 from GM or a junkyard. One is more likely to give problems than the other which is why the other is cheaper. I live by the idea that nothing good is cheap because it doesn't have to be and nothing cheap is good. Sometimes, something comes along and breaks the rules but those are fewer and far between.
No, the definition of "hotrodding" is: modify (a vehicle or other device) to make it faster or more powerful. You will have to pay for it either in sacrificing reliability or "elbow grease" or some other fashion. As they often say "Fast, Cheap or reliable. Pick any two.".

Notice how I said "nature" of hotrodding and not "definition."

to get back to the OP's original topic-an LS wouldn't take much at all to hit 400hp. The gen I sbcs have been done a million times over. with all of this in mind if you aren't planning on doing the work yourself I wouldn't even consider trying an Ls swap and probably not even building your own Gen I. a lot comes down to personal preference. if you've got deep pockets might as well just buy a new Vette. especially since C4s are widely considered the ugliest Vettes. 😁

Of time is the issue, stick a 383 and get it tuned. Problem solved

I had a good weekend to think and drink on it, and I think I want to keep the car together with its original block. It needs to come out anyway and get cleaned up/re-painted. It had just been bored, decked and fluxed 5k miles ago by a shop for the PO. So assuming it was done right and in good condition, doing a nice build off of that really makes the most sense. I can retain all the current pulley drive system without any fab headaches and end up with a nice, reliable SBC build.
Anyone running a FAST Ez-EFI setup on their cars? Just curious how that integrates with the other electronics/ECM? Also, anyone made the switch to the FAST distributor and separate ignition box? If I went with the Ez-EFI setup, I would go ahead and change the distributor so it can have spark advance/retard control.

Why would you need to change the advance? I'd like to see someone show me how much more I could get out of the motor to justify the setup. I have set mine and forgot it. If you are making radical changes every month, sure. Otherwise, it is tuned once and probably left that way for years. Ability to change things is nice. Ability to use that change is more significant than just having it. IMO

I know a lot of people desensitize the knock sensor to get as much advance as they can. Kinda like advancing the timing all over. You might have all of that set up properly via the ECM programming done on a dyno so I am not sure why you would want to increase the risk by meddling with the control if you don't have to. Again, if you are racing and don't care about the motor as long as you win the race, cash the sponsor's checks and buy a new motor, fair enough.

I'm running the fast ez efi in my car. Fast sells a sbc system and a distributor that works with their system. I would also set-up a crank sensor. You may have to upgrade the injectors as I'm not sure if the fast efi will connector to the older SBC injectors.
The edelbrock xl pro intake manifold works well, that way you could run the newer throttle body, injectors.
Do a compression test on the current engine? If its in good shape and has good compression, I would install another camshaft (something with a more modern grind), 210cc aluminum heads, roller rockers.
To bad you don't have time to work on your own car right now. I had a blast building my car last winter. I can't wait to get back at my upgrades.
Post pics of what you got. Thanks for sharing. The C4 is such an awesome starter platform for fun driver.

Unfortunately the issue comes down to time, not necessarily money and skill. My weeks sometimes can carry 100 hours depending on volume and I got the car so damn cheap, putting money in the car to bring it up to where I want would put me around the price of a highly clean C4. Call me a die-hard, but C4s just just do it for me in terms of styling. They just need a little massaging and subtle updating. It's the same thing when you see a really well done IROC-z or a well done fox body mustang. They just need a little TLC outside of their bone stock form. But I totally understand what you mean man
I hear ya on that man. I can't believe a lot of ppl think C4s are ugly.

Thats good, then we can still get em for cheap
Dont think they are ugly just not striking..what kills the look imo are some of the wheels that was the star wars era.
never went gaga over them but they do look good clean with a stance, whats great is what they offer for the $. Good handling, not heavy, ac power accessories. 350s are cheap as hell to build. You could buy an 850 shortblock fill it with whitebox cams etc and still make reasonable power.
The Lsx only needs a little headwork and a small cam to hit 400;if you can DIY its cheap. Paying someone forget it
Aftermarket parts for Gen 1 are super cheap in comparison;price an MSD intake manifold then $500 to port it.

I'm all ways changing how my car sounds at idle. I can make it have the old school chopping idle or a new car smooth idle just by adjusting base timing or even lower/increase the idle speed.

this.
wheels make a huge different appearance wise.
around my way ppl are giving these away for around $3k for a clean early model.

Aklim I hear ya but just wanted to point out why is nice to be able to adjust the tuning from inside the car, when ever. What happens if you get a bad tank of gas or accidentally fill the car up with 87 octane (ok with a stock L98 engine). I can adjust the timing driving the car, drop the base timing, add vacuum timing for cruising. Change air to fuel ratio depending on % of load, can be used to increase fuel mileage. Sometimes that special tune if off at certain loads or temperature or fuel quality. Sure nice to have the ability to adjust on the fly.
I'm all ways changing how my car sounds at idle. I can make it have the old school chopping idle or a new car smooth idle just by adjusting base timing or even lower/increase the idle speed.

Not sure if timing alone can do that but I haven't tried it yet

EZ EFI systems do not incorporate knock sensors. I have the 2.0
If you want more info on it, PM me, i'll shoot you my phone # and run through a lot of things that I had to learn when putting mine in.
As far as integration with the Dash, you'll have to run a separate VSS wire since the VSS wiring is integrated in the original ECM harness. Fuel pump wiring, speedometer, tachometer, oil pressure are all connected below the passenger side hush panel, just below where the factory ECM mounts. That's how I did mine

Preach man! I've got the stock 89 wheels on there now, once I get the rest of the car set up, i'll be looking to maximize the wheel/tire combo. Just going to fit as much rubber under there as I can without it screwing up the look and sticking out of the body
Pure toy bliss man. This is exactly why electric cars will never take over the world.

To each his own, my friend. Sound is visceral for me and it's part of the experience of driving the car. Conversely, the other end of the spectrum is a conservative prude who yells at kids on his lawn and eats dinner at 4:30pm to save a few bucks. We all fall at some point on the spectrum.

Don't know. I don't want kids on my lawn either but dogs are welcome.
If I sleep early, I'd eat at 1630 to save a few bucks at a restaurant. OTOH, I eat later because I sleep much later so I don't want to feel hungry at 2200 and have less choices of what to eat. Trade off is I don't feel hungry late at night for a few bucks of savings.
