bloody miss

ok i have just got a fully rebuilt 350 holley put on my 4m it had a 350 holley b4 but ran hella rich so i took it to a carbie place and the guy said i have the wroung type of 350 holley on there so he said i'll put the right one on there for $300 and install it for $100
so i went and picked it up and it ran worse than before 
(this was with half an exaust so it was loud as fk and didnt want to idle so i got the exaust fixed and brought it back.
the guy said its not getting enough fuel so he put an electric fuel pump on (carter fuel pump - pumps 6psi) it ran better but still had a miss but it wasnt constant it would do it every now and then.
he replaced the plugs, points, condesor, rotorarm and set the timing, he also tried colder spark plugs as it was running rich and said he had put size 58 jets in there from 61 (  jet sizes mean nothing to my feble knowledge)
and still had an intemitent miss
so he said i reckon its the distributer so he suggested electronic ignition
but my wallets getting pretty slim at the moment so i thought id get a second opinion so i rang a performance tuning place they suggested this other carbie place
i told the guy what the go was and strait out he said its the carbie he said its to big he said " the carbie you wouldve had on there before wouldve been single throat the 350 is dual"
he recommends a webber i said i'll bring it in and get him to have a look
what do you guys reckon/suggest?

Yep. Bolt on the 5ME fuel injection manifold and ECU.

fuel filter?
Condition of carb?
A weber will only solve the problem if the problem is the current carb.
What cc's is a 5ME? - a 350 is getting towards large for most toyota's isn't it?
I hate mystery misfires!

I have a efi from a MS112, harness etc. Yours for the price of freight from Sydney if you want it. PM me if you are interested.

sell the holley to buy EFI hardware...
a single H 350 is big enuf to power a 265 hemi valiant, it's too big for a 5M.
even dropping the jet size won't help you much - they're designed for big-breathing engines (like big fords and valiants 6 cyls).
if you don't like the idea of going EFI then get a factory carbi, rebuild it with a carbi kit and get a HEI kit from dick smith or Jaycar (approx $50) to improve the spark. the holley's only good for stoping the shed door slam shut on you.
also, intermitent miss with throttle steady would be spark, not fuel...

wont i lose power if i go efi?
to setup the efi properly woundlt i have to get it tuned up + dont you have to have electronic ignition with efi
so i would need the efi manifold,ecu,loom,electonic igintion dont you need to put sensors in the exaust and intake?
that sounds pricey
i've spent like $250 on the air filter for the carb (k&n element with k&n extreme top) so then id have to get all the efi set up then another air filter.
I love the sound of the carbie suction and want to stick to carbie until i do a conversion
one last thing whats a HEI?

HEI = high energy ignition.
Isn't your motor completely standard apart from some headers/exhaust and the wretched Holley?
The EFI system really will be able to cope with the minimal improvement in airflow afforded by the exhaust.
You buy a full EFI system off a 5ME. If you look around, loom ECU, dizzy and intake manifold will set you back $150. MX62 Cressidas are currently the wreckers pet hate. Get your drop tank modified to take an MA70 in tank EFI pump.
Sell that POS Holley and Carter low pressure fuel pump to fund your upgrade. This way you will have setup your fuel system for when you do decide to do a conversion and you will have a perfectly reliable EFI setup that you never have to tinker with again. You'll also learn all about EFI with the most basic EFI system, and come to realise how much even this basic EFI system shits on carbs.
As an aside, I'm not sure why you got a Carter fuel pump. My standard mechanical 4M fuel pump pumps enough fuel at 7 psi to fill 3 fuel bowls at full throttle. In fact, I had to adjust the fuel pressure down so I didn't overwhelm the needle and seats in the SUs.

Just take your time, sounds like there is no great rush.
Justin (clubagreenie) has some bits that you can have for free (+postage) and I have a range of bits you can have for free (+ postage).
Is there a Pick a Part style wrecker in Perth? Often they are quite well priced.

Setting it all up is a weekend job at a fairly luxurious rate. You could use a VL Commo fuel pump at a push if you didn't want to do the in tank bizzo.
