'75 and earlier exempt. Enjoy your annual safety inspections.

>>14259587

Why would I not flash different runtables and hotter timing to my ECU for WOT, and saving fuel the other 90% of the time?

I owned one and hated it... It stalled when I didn't let it warm up in the cold. I flooded it a couple of times when starting, and had to wait a minute or two. In other words, don't get a carb if you are every in a rush and want to be able to drive off immediately!

>>14260077
Power is directly related to efficiency, though.
>>14260127
Wrong, this is not legal at a federal level, and for good reason.

There's literally no reason for it to be outlawed except in the minds of the cuckold liberals trying to ruin cars.

Also if you don't know a mechanic who would wave your car through inspection you deserve to get fined.

>>14261152
ok well it is illegal federally regardless.

Yes, there is. You can't alter emissions control equipment.
>Also if you don't know a mechanic who would wave your car through inspection you deserve to get fined.

I don't need to know one, because my state doesn't have inspection and, if it did, I would easily pass since I keep my car compliant.

Have one on a Yamaha lawnmower engine. Runs good.

Fun fact: If you don't like carbs you don't like cars either, and should fuck off back to /g/ or /sci/ with the other nerds

Although I'm counting down the days until I go EFI.

You'll end up spending around $6,000 on drivetrain and have a vehicle worth exactly the same in the end.

If it's an automatic, a manual swap will improve the value and make it a nicer drive. A M21 would be a good investment.

but we all know an LS is better numbers wise, but there's something bad fucking ass about an old school muscle car with a big block.

like the other anon said, it couldn't hurt to install an M21 manual and some aluminum heads would free up some ponies and reduce weight.

Honestly the biggest thing is the weight. I'm never going to make a fatass big block car turn as well as an alum block.

I'll spend this summer doing burnouts on as many country roads as possible and enjoying the engine, but it just doesn't fit in with my long term goals for the car. I'm hoping some day to have it caged and on a track.

So in the process of getting amped for rebuilding one of the spare 4 barrels that came with my foxbody I've been watching this video

https://www.youtube.com/watch?v=KAu3L2BhnvE

I like the filmstrip one that's straight outta the 40s but something about this guy's accent and the length of the video just makes me feel like I'm getting the most out of my time.

>>14261817
You're gonna get real close with Hotchkis over the next couple years.

>>14261817
I feel that man. your camaro didn't come with the 427 originally did it?

>>14260028
I have a 79 240d which I love to drive, except for right now. Diesels are a total piece of shit for my Canadian winter. Thankfully I have a 1960 220S for the winter and recently picked up a 77 280e.

>>14261849
I'm actually looking at the QA1 stuff right now.

>>14261858
I don't think any Camaro ever came with a 427. Vin says it was a 350cu car originally, so it's not like I'm ruining a numbers matching car. Plus it has aftermarket t-tops, which also ruins collector value.

>>14261152
If you live in a liberal shithole that inspects your property, you don't deserve freedoms.

>>14261622
It's what's on the current motor and what was on it when it was bought. I'm not sure what ls going on the new one. Me and my old man are visiting the machinist that's working on the motor and we'll see what he has to say

>>14261881
yeah then I guess that is fine. why you want to go with an LS2 though? why not LS6 or LS3? LS3 is better all around.

>>14261901
Because I'm a broke bitch. I can still pull 500hp na out of an NA LS2, but they're more affordable than the more desirable 3/6/7 motors.

>>14261919
I hear that. have you looked into the LQ4 or LQ9?

>>14261956
Trying to avoid an iron block, but we'll see how much I get out of the 427/TH400. I'll go LQ9 if I absolutely have to.

Well I've got a friend at Spalding's who thinks he can get me the LS2/T56 for around $4k. If that's true I'll shit bricks.

I'm hoping to get $6k out of my current setup, so that would pay for the whole swap.

>>14261677
Would you consider the new challengers kinda factory pro-tourers?
I understand that factory fresh kinda defeats the purpose,but...

>>14261020
Sounds like you just needed to adjust your carb, and work the choke properly.

>>14261973
If you look carefully, you can find an aluminium 5.3, those are even cheaper, and they've got more room for an overbore iirc. Way more boost-proof too.

>>14262151
Yeah, the L33's for the Trailblazer SS. It's an option, but the price on those are creeping up and they're a bitch to find. I'd probably build one of those for a high redline, similar to the old screamer 302's they put in Camaros for Trans-Am

>>14262180
You'd want a 4.8 for that, those have a smaller stroke.

>>14262195
But you need an LS3 block for that, otherwise the bore size ruins it.

I might look into seeing what kind of cranks are available for the LS2 to get it to a shorter stroke.

>>14261622
750-850 depending on how hot it is

> mfw going EFI on a multi Carb setup
Well I would post a face except I don't have one that mixes excitement and disappointment.

>>14262232
I think you can get away with the LS2's 4'' bore size instead of the LS3's 4.06''.

>>14262251
Doing more reading on the subject, it looks like an LS2 can do a 7k redline with the right cam/spring combo. I don't think I'd want a street engine to rev any higher than that anyway.

>>14262366
>not wnating to run 5.11 gears,, running through the traps @8500RPM

>>14262366
even if you are doing road racing, you just don't need that kind of redline if the rear end gearing is right.

>>14262370
Trolling DOHC guys would be hilarious, but other than that it's not worth the investment.

more revs=more power

Carbs can make just as much, if not more power than EFI can, the problem is in terms of emissions and fuel economy, there's just no question: EFI all the way.

Usually carb guys are people who don't understand a goddamn thing about carbs other than, "Well, you bolt the motherfucker on and it goes!" and disregard the fact that carbs are actually 10 times more complex than EFI. Not that it matters, as the fuckers never bother to set it up right. Like my neighbor, dude has a 850 cfm on a chevy 350 that doesn't spin about 4 grand, choke is disabled because it's too complex for him to figure out. Also he didn't bother to block off any of unused vacuum ports, so it runs like shit and he can't figure out why, he seems to think his pistons must have been defective.

>>14263844
Carbs make far more power than EFI when tuned. Only problem is libcucks crying about fuel efficiency.

Hey guys I just bought a carb'd Accord in the fall and I was wondering if you guys had any tips about starting it in the cold. It was 20 degrees this morning in PA and its gonna get colder soon.

>>14263844
I don't understand how carbs could make anymore overall power than EFI, especially WOT when essentially all either system is just dumping fuel at that point.

>>14266610
*peak hp

https://www.youtube.com/watch?v=2sQJPZYSoUI

efi is more efficient at making power across the range.

>>14267133
Buy a can of that aerosol engine start crap, spray a little into the intake. Not too much cause it's very volatile.

>>14261881
only the c.o.p.o. cars, you could get an all aluminum race 427 if your dealer knew the right boxes to check.
>>14267133
press the pedal slowly to the floor once before starting to engage the choke and fast idle.

>>14259946
without some o/s valves, seats and portwork that much carb will do fuckall but make noise.
