What set up is best for Stock 5.7l in 88 Camaro
Hi I’m going bigger from 305 tbi to a stock vortec 5.7l 350 carb in my 88 Camaro and my Machanic wants me to go with this set up, single plane edelbrock intake with a 600 carb single inlet. Is this the best setup, will it work, and do anyone have a better set up I can suggest to him, oh and this will be my powerful Cruze machine and when I wanna get on it I can still shoot out at the light thanx a lot

Why not stick with tbi ?
Get larger injectors and a custom tune. Or use a 1227747 truck ecm .

If you're intent on going with a carb, then ditch the single plane intake and go for an RPM Air Gap. It will, at engine speeds below 6500, give all of the performance of the single plane but provide better low engine speed performance. Or at the very least, pick a higher end dual plane like the RPM Performer (or similar). The single plane is likely to suck any life out of low speed driveability.
600 CFM may or may not be enough (but my guess is it probably will be) but the single inlet reduces your ability to tune effectively. Typically the single inlet carb (quite possibly the one your mechanic has on the shelf and is trying to unload...maybe) will not have secondary metering jets but rather a jet plate. That makes it difficult to work on the air/fuel ratios. Another feature that is often present on a dual inlet carb (but not always) is four corner idle metering. That is also helpful when trying to dial it in.
The intake suggestion here has more impact than the carb.
Has there any thought been given to the ignition? Will you be ditching the ECM?

hi thanx a lot for the info and I ended up going with the air gap and single inlet holly 600cfm and I’m hoping for the best lol but as far as the ignition I’m going with a bullet distributor with blaster coil and 6a box
Re: What set up is best for Stock 5.7l in 88 Camaro
Same ignition as I'm running (MSD 6AL and Blaster 2 coil) although I've got an MSD distributor with vacuum advance. I hope that bullet distributor you've selected also has vacuum advance. It has a huge impact of fuel economy and driveability in general.

Whoever told you that combo, obviously has very little experience building cars of this type THAT WIN. On the street, the oval track, the strip, or anywhere else. It's a recipe for a disappointment from somebody that doesn't know what they're doing but maybe reads too many magazine articles without understanding how these motors work.
A STOCK Vortec 5.7 has a seriously weeeeeeenie cam in it; 19x/20x duration @ .050". The cam alone prevents it from making any power AT ALL above about 4500 RPM. OTOH, a single-plane intake guarantees that a motor won't make any power at all BELOW about 4500 RPM. That combo basically guarantees that your motor will NEVER make any kind of serious power at ANY RPM whatsoever.
The ignition system is almost irrelevant. I've seen people put MSD stuff on cars and make 30 HP more than whatever they took off; I've seen people take off MDSs and put in DUIs and make 25 HP more; I've seen people put in stock GM HEIs and make more than MSD. There's more to making an engine produce power than name brands: it's the thing we call TUNING. Frankly I don't think the MSD stuff is of any value at all on a street car. A PROPERLY WORKING ignition, absolutely; a brand name, no.
If I was doing what you are doing, I'd put a cam with about 215° - 220° of intake duration with about .500 - .520 of peak lift, about 10 - 12° more exh duration than that but maybe a bit less lift like maybe .480 - .490" lift, a Performer RPM intake (DUAL plane), a DUI (because it comes pre-set-up with a very good "performance" tuning curve), SERIOUS attention to the exhaust system which you don't even mention, a 3000-ish stall torque converter from a GOOD source (not TCI or B&M, maybe Circle D or Yank for example), 3.42 or 3.73 rear gears, and rear lower control arm relocation brackets.
Your post doesn't strike me as coming from the US. Where are you located?

x2 single planes shouldnt even come into a build conversation unless the expectations are pretty high.
Mild engines a single will make your car slower. You need to hang the valves open longer, get more through the heads/exhaust.
Bolt ons are overrated. I know the F and F with their "full ????? bolts ons" is a popular saying but back in the day noone said that. everyone had headers a 4bbl small cam.
What are half bolt ons....whats a stage 2.5? lol
