Here's mine at the last car show before I ripped her out again

I know you like the nice red "X"

Doesn't want to work for me for some reason

Actually, the rear portion of the stock front subframe on both sides has been completely removed (along the sides of the trans), and a full 2"x3" frame now goes to the rear of the car. A custom made trans crossmember was also fabricated. This makes for a whole lot more room for big collectors, while still having sufficient ground clearance.

are you running full exhaust or just headers...4" exhaust sounds bad....:rockon:

update on my motor...Philedelphia Racing Products cable bracket, ac delete box in. the cable bracket is bad. ya'll should check it out if you have a chance.

Yes, it's got dual 4" exhaust with Flowmaster mufflers. Since the car has been back-halved and doesn't have a rear seat, I raised the floor in between the 2x3 frame rails (where the rear seat was) to make room for everything. I'll see if I can dig up some pics...

Me likes.... It's sooooo good to know that I am not the only one in the III Gen class running old school carb's! Yeah, cold starts suck, but the power is worth it. Can someone please e-mail me or post (that is those running carbed III Gens with over 500HP) what fuel pump your running and how you adapted it from TBI or TPI to carb for pumps? I am thinking of holley blue, but is that enough? Do I just splice into the fuel line and run that pump and let her rip?

Better yet, let me make a poll (a small one)

What fuel pump do you (carbed folks) use? Why? Easy usage?


Thanks

No ones answered my question yet so i figured ide give it a shot in here. im swapping to carb. 350 soon, and i just bought a SS hood that came in last night. just wondering about intake manifold and breather clearence? i wanna run a RPM intake, but their kinda tall, so i didnt know if the hood will shut.

I'm gonna try and make one of those brackets... 75 bucks is too much for a damn throttle cable bracket lol. They look cool though.

hey, if you can make it, more power too ya! i love the way mine looks though. It's CNC Machined and like 5/16" thick with the blue anodized finish.

as far as the fuel pump deal goes, i like mechanical stuff. i am going to upgrade my stock replacement mechanical to a mechanical edelbrock performer street pump. should support 550 n/a horsepower. it's like $74 through jegs and doesn't require a FPR like most electric pumps.
here's a pic of the edelbrock pump

Those pumps are a very tight fit in third gen cars. They are practically against the K-member. I had a Holley version (exact same 6 valve pump) back when I had a SBC, and had to reclock the lower portion so the fuel fitting would clear. Even still I had to dimple the K-member slightly. A neat thing about these pumps is that they're rebuildable.

i'll make it fit.

First: lilthurmy03 with that SS hood you should clear your set up, just by the hair of your chin. I did it with a 3" cowl hood. and could have did it with a 1". You will be okay.


Second: You guys would rather run a mech pump than a elct pump? why? I am new to the carb swap pump stuff, but was told stay with the stock in tank pump, ad a elct holley pump (any brand) and a AFPR and that is the best? Don't you have to get in the gas tank and set something up for the mech pump to work on switching from TBI to carb?

first off, if you have a fuel injection pump in tank then it should be putting out like 50psi, you don't need a second pump. just run a 3way reg. with one going to the return line. yes, if you run a mechanical pump, you need to drop the tank and pull in the intank pump out, extend the pickup and then put the tank back in. also, take out the inline fuel filter. put one AFTER the mech. pump, before the carb. sounds like quite the motor you got for not knowing alot about carb swaps....hope this board helps...

second, a mechanical pump will go as long as the engine is on. the electric pumps have to be wired into the system, and with my luck with electricity, i will blow fuses all day long. they are also very LOUD! i am also going to run a procharger with a blow=thru cap on a 650dp. with a mechanical pump, all i have to do is plumb a vacuum line to the top of the pump from the hat on top of the carb for boost control. with an electric, you need all kinds of regulators and stuff. i guess i am just old school. i think that this way is cheaper and easier. the money i save on the pump will go into getting nice braded line and all AN fittings and stuff.

Okay, first I am not coming off as a jerk, but the line you said above "sounds like quite the motor you got for not knowing alot about carb swaps" is just why I came to this board (the carb board). I have been dealing with 3rd gens for years now, but only EFI third gens. This is my first carb swap and that is why I have a few questions. To say that "my TBI in tank pump that puts out like 50psi will work for my set up" is WRONG! Sorry to say, but I have the set up running just that way, with the TBI pump and a holley AFPR set at 7psi for my carb. That works at idle, but as soon as I give her some gas, she dies like it's not getting enough fuel. Which is why I ask about the eltc pump. The eltc pump would be easier to install that dropping my tank to use a mech pump that would more than likely cost me more on the mech pump, something that will support the HP I have going. I have talked to many people on this board about this already. When switching from EFI to carb, the stock EFI pump will not support the carb. The PSI on the stock pump is to low. I know this now after reading posts that said just what you said above "just run the stock pump with an AFPR and it will be fine." NOT TRUE! So I ask, will a holley blue be enough for a over 500 HP motor (carbed)? And later down the road a 200 shot of n2o? Will I have to use 2 holley blue pumps to support that much HP? Right now my car will only start and idle, maybe a little gas around the block, but when it comes to hitting the gas hard, or even a little hard, she dies out, not enough fuel, BECAUSE I am using the stock TBI pump with an AFPR which will not support a carb set up such that I am running. Maybe it works for folks that just take off the TBI and put a carb on the stock 305 or 350, but not for a built 388 stroker.

I am not trying to be rude, I do need experiance and help in this matter, and your thoughts are needed, however, I do have knowledge about carbs, racing, motors, ect... Just not carb swaping from EFI. I am learning, and this board is my key to it all and all you guys who have helped me.

My goal now, after returning from Iraq, is to get this beast running strong for this summer. I just need fuel pressure to support it, so I ask what is the best way? I would like to use a holley blue (because of the price, you cannot beat it).

Thanks for the help, and yes it is quite the motor!

Also mw66nove, could you e-mail me some more pics of your set up, it's clean like I like it, you removed all the A/C and heater ****, washer fluid bottle, etc... I did the same, however, again I need information and pics on what else (that I have not already removed) can I take out.

Already I took out everything on the passanger side (a/c, heater, all it looks like your with the holes from the items left in the fire wall, which I will cover with a pice of sheet metal soon), removed the windshield wipers, the motor, wht else and can you send me pics?

Thanks

Here's the 388 it used to have, that was until the oil pump pickup head came off and toasted it!! Oh well it lasted 6 yrs and it ran 11's before it gave in.

Didn't catch this till now but.... I have access to a couple of CNC machines and a place that does anodizing Actually getting it done isn't very high on the to do list hehe. Just like replacing all the stock gauges with Ultra-Lite gauges on a bolt in black anodized aluminum plate.

my car is nothin' special yet! it is a knockin 305 w00t!

you wrote in pink....hehe, that's funny.

Uh i have the stock TBI pump still in my tank, and my 388 STROKER runs pretty dang good. I'm feeding my Speed Demon 750 with just that stock pump!!! What is the issue here?? My car runs 11's, that was until my recent oil pump mishap

I am using a cheap TBI replacement pump in tank w/Mallory regulator feeding a 750 Holley without fuel delivery issues. Even still using return line to tank.

Then why is my car dying out when I give it gas? I was told (now) 2 different things that stock TBI pump will not support my set up, and now a few of you guys telling me something different? Cany anyone help me out? Do I need a eletc pump to support this or what? Why is my car dying out when I give it gas (with tranny in drive)? It's like once I give it gas and she starts to get moving, she just dies out???? HELP, I don't want to waste more money, because I just spend major bucks on a new fuel set up... Thanks for the help, this dying out when I give it gas is killing me????

My mods are listed below::::

HELP

here it is, kinda crappy angle and lighting...

updated pic...what can i say, stuff happends, i will keep you guys updated on the progress of the new car...once it gets here LOL!

ouch, mine looked like that but dead center. a lot of work to fix that stuff man. did you bent the brackets the bumper bolts too? man i hope i never do that again

i pushed the whole front of the car into the unibody about 3". those pics don't do it justice. the crossmember was even pushed back. it's pretty F'd up. prayerfully the motor isn't toast. i haven't had an opportunity to get the motor out of the car yet though.

figured i might as well join in on this fun thread once in my life....lol...these are from cardomain site.

Okay, once I can get some pics I will post them. I figured out why my car was dying out when under a load. The plugs where dead and the fuel line had a kink in it, not allowing enough fuel to enter the carb when at a load. I also put a 140 GPH eletc pump, new fuel lines and a new fuel pressure gauge to be sure it would not happen again. With the right set of NGK plugs and the pump, I hope she will be running right very soon. Also had to get a min-starter, as the new one I got (a regular size one) was rubbing up against the headers and getting rattled all to hell. So, I got a new mini-starter to go along with it. Will tune her up and see what happens. Pics to come soon...

good to hear you got it together...hope for new pics and good news.

Nothin' special or fancy "orange and chrome don't get ya home" Looks kinda different nowadays with a few more goodies bolted on...

Nice pics everyone.

I'm going to begin building my 383 in teh next few months.

What block did everyone use to get the alternator set up to mount on teh pass. side?

Is it just a new bracket or something?

I just pulled my A/C, and smog stuff is comin off this week.

How'd you do it? Anyone fit a carb/aircleaner under a 2'' cowl?

No special blocks used to mount the Alt. over there, heck mine isn't even bolted to the block, it attaches to the water pump. I bought the brackets from March (the company that makes underdrive pulleys). And about the air cleaner fitting under a 2 inch cowl hood, mine fits under a small scoop i mounted on my hood, after i cut a whole in it!

Any specific website for the alternator relocation kit?

I found March's website- nice stuff- but $$

Anyone know where I can just get a "stock" V Belt system, like whats on the family 73 Vette?

Since this thread is still going I thought I would post a pic of the new 406.

Should run mid 12's when I get it hooked.

hey barry, what kinda hood ya got there?

Only the best...........ram air. Cut out in the front and the back. And with that air cleaner, it gets all the fresh air it can handle. When I put the hood on, I had to bump the jet size up one.

Here's my carbed contribution. Soon to have a few more changes in Spring time.

We just had the annual Houston Thirdgen gathering, and I had the only thirdgen carburated car there. WooHoo!!!!!!!!!!!! I can fix my car without a computer!

Here's mine.

I guess everybody is posting there motors --- why not...



Ron

man ron, that march pulley system is awesome in your car! i wish i had $300+ to spend on pulleys.

Things you will never hear me say;
1. I think my tps needs to be adjusted.
2. I need a scan tool so I can see why my check engine light is on.(bulb removed)
3. I wonder if my total timing is right.
4. I might have a dirty injector.
5.Changing the fuel pump is REALLY gonna suck!
6. 8 new injectors are HOW MUCH???????????????
7. I need to have my plemun ported.
8. I have a bad o2 sensor.
9.etc.......

you'll never hear me say ....that bad "e" word


emmissions aren't around here with show car insurance and only driving under 500 miles or so a year.

I wasn't that hard...I kept throwing V-belts like clockwork @ 6K rpms (In fact my camaro also throws them at 6K!!! WTF).
So hell no belt throwing & less rotating mass, made it an easy buy for me.

Hey Barry, what about OPEN LOOP???? pun or what?
Have to file that next to safer bullet


Ron

Forgot about that one!!!!!!!!!!LOL
