Ok I have some questions for you guys that have done this. I'm doing initial planning for a 350 crate of some sorts for my 81 with 305 4sp.

1. Is there any reason to keep the computer at all? Like any other system I might need it hooked up for like EVAP, EGR, AIR.

2. Anyone done a crate motor install and kept the E4ME carb and like it?
and...

a. What emmission systems did you keep and what did you give up.
b. How do you keep the check engine light off if you did get rid of a system..

3. I am pondering whether to put any money into my current E4ME before transplanting onto a 350, or skipping it all and going straight non emmission Edelbrock performer carb. My plan is to get my fuel delivery system and final emmission leftovers sorted out on the 305 before dropping it all onto a 350.

Your thoughts?

Me no trusto the mixture-o control-o solenoid-o.

archerm3,
I'm not to sure on all this emission garbage but I'm sure to computer won't like the bigger motor. I am pretty sure you would have to upgrade your sensors along with the motor. There is a slight difference in the output of a 350 over a 305.

I have a stock (sort of) 305 in my 84. The slight mods kept the check engine light on. I pulled the bulb out. If you are familiar with how everything should sound and act, pulling the bulb shouldn't bother you. Just watch you guages.

I prefer to keep the 305 because my truck is all factory. It has a low production number from Choo Choo to boot.

Yeah, I have no desire to keep anything motor wise stock, really, because stock parts are so hard to find anymore, engine wise, and the only people that know how to adjust them anymore are on this board, i.e. not in my hometown. I can do a lot of work myself but I don't enjoy it. For me it's not a labor of love. Just labor Hahahah.

I really really hate diagnosing mixture solenoids and ECM issues without the proper documentation, experience, and diagrams. I don't really want to make myself another expert on the E4ME, though I am an expert on Toyota landcruiser carbs. Been fighting that damn mixture problem for years, just in the past I would just buy a rebuilt E4ME but no so cheap to do that anymore.

I want to get up into the 300 (-) hp range with decent efficiency, with something easy to adjust/tune.

Well, if you don't have to worry about emissions then just rip it all out and go with whatever your pocket desires. All you need is positive and negative and a guage pack.

Your computer and E4ME carb will handle the 350 motor. You say you will have the carb rebuilt, tell the rebuilder it's going on a 350 motor. Not sure if that makes any difference unless you are hotting up the engine with other mods. You can remove the air pump and use plugs for the exhaust manifold threaded holes. And remove the line to the cat they are not computer related.

Why even consider a carb of any type ---for just a few bucks more you can get a Holley Projection fuel injection system and get all the benefits of a more efficient more user friendly engine---there are other ways to do it to but thats as simple as I have found and it can be upgraded as far as you want to go----I have one of the projection 4s that I am putting on the small block 400 in my elcamino............Dan

I'm having a hard time telling whether or not this is a joke.

A "few bucks more"?

A rebuilt quadrajet by a place like The Carb Shop will be around $350.

The Holley EFI system is over $2k.

Really????? then check on the price of this setup:http://www.holley.com/BrowseCatalogs.asp?Catalog=Holley&Page=173
I think you will find it closer to the 700 dollar range and usually in the 250-350 range on ebay.......................Dan

old_coot,

I've been considering that set-up myself for my 4X4. I hear that it is a fairly easy bolt-on. Q-jets are great, as long as they are working properly. This one was set-up for high altitude. I moved back to the south and sea level so gas mileage sucked. Tried to jet it down and got worse mileage. I put it back and drive it less.

I'm planning on doing a complete turn key engine swap soon, so I will adress that issue then. Good advice though! :D

If you brought a high altitude adjusted engine back down to sea level, shouldn't it be running lean instead of rich?

Yeah, I don't think so. Maybe if I had another 3K laying around...

Pricing just that TBI alone (502-20S) was around $1100, without any brackets, or the closed loop controller.

A TBI without closed loop is just a carburator with an electrically driven instead of manifold pressure driven fuel curve.

Additionally, it's only good for 275hp....Non emmission legal, and not for computer controlled carb cars, going on my 81.

A 670 CFM throttle body will support a lot more than 275 Hp the limiting factor on that Particular one is the fuel injectors --they start at 55 lb/hr but they make them up to 85lb/hr and are interchangeable----that system comes with the controller, fuel pump, wiring harness and all,---Hey just so there is not misunderstanding I have no affilliation with Holley or any other product I am just trying to help----I think any form of Fuel injection is a vast improvement on any carb setup for anything other than an all out race car---I have converted several type of engines to factory style fuel injection plus I am in the process of building a monster engine for my 86 Buick Regal T-type and have a Megasquirt system to control it----the Holley system is by far the easiest system to get on the vehicle and get up and running well---all the suppliers I have dealt with are willing to "deal" on the price --with the exception of the big houses like Jegs and Summit. but since we are talking about a rebuilt--(another word for used) carb why not a used projection system ---I have used several that I got from Ebay in various conditions---a couple needed replacement parts but the majority worked fine---there was a request for suggestions and I put my $.02 in ---sorry I didn't mean to hi-jack the thread....................Dan

archerm3,

You would think that it would run lean. This has my mechanic bewildered. He has been working on Q-jets most of his life. It is his bread and butter. Even the carb place that jetted the carb is baffled. They built the carb for me in Utah. I went back to them for the re-jet. Its been a head scratcher.

No, I really appreciate the input, and for the record I am a BIG fan of fuel injection (as long as it's closed loop) but I'm thinking that the price you suggested is way off, not that you haven't done it for that cheap but every time over the last several years I have looked at it, it was always way more expensive. I just cant find these sources with these discounts. I don't think I would trust an electrical piece over Ebay until I had played with a few and learned that particular system first....No warranty, whereas a rebuilt carb would, theoretically. But most of all, I see myself into fuel injection for no less than $2000 after all said and done fuel alone, and that kills my budget.

My buddy put a projection on a crate 350 in a landcruiser back in 1996 and I watched him do it, very painless, but very expensive.

You may want to check this one out for the price---full closed loop system and still in the box:

And you are right to question it but so far I have been very lucky---every one that has had a problem was noted in the ad and went very cheap---just look at the feedback from the seller before you bid---I have made a little over three hundred purchases from Ebay and only two bad experiences---better than most parts stores actually---I currently have seven keeper cars and all are fuel injected--their models are from 54 to 98 and the last few I sold had been converted--the fuel economy is only a small part of why I think its worth it---the starting and drivability factors are at least as high on my agenda---not to mention fuel leaks and odors --vapor locks especially with quadrajets used to really fry my potatoes----I have just lost interest in fighting those battles---anyway I wish you well with your choices.......................Dan
