The GM TBI is the way to go. I'm tapping my foot for JTs when he has had enough

But on the tbi conversion I suggest having the correct computer (1994) that can be reprogrammed with a chip for tuning purposes. I've never seen one run just quite right. It seems there is always a glitch somewhere because they use a one size fits all approach.

I'm all about polishing turds, but I would do a late 2F w/TBI over a 2FE any day because it is so easy.

I would also do a TBI over a carb rebuild.

The AFI kit I had was a super simple system and ran great. Zero glitches. I don't know what year computer they use but they supposedly program it for the 2F. I didn't feel it needed reprogramming, but it did have the chip if you wanted to tweak it.

Hot, cold, 10,000 ft, -200 ft. Ran perfect.

Guys,...listen to Cam!
He is spot on! After I got mine set up. I NEVER had problems. AFI is the way to go.

Ok, I just know that the efi forums have had quite a few requests for help on 2fs with AFI fuel injection. AFI will help out a bit when trying to get it right. Devin was even contacted by a guy 2 hours away who wanted to hire him to tune his. JT had some trouble with his idling when we were at Clayton. All that being said, I agree that TBI is darned sure the way to go but I would want to do a lot of data logging to burn a really good chip.

Machinist asked if the 2F head bolt holes are blind?? Meaning coolant doesn't pass through block where head bolts down. I said no, but thought I would check with the experts here.

Said he magnafluxed the head and said that process has missed cracks on rare occasions.

Also said porosity could be the issue when he hot washed the head??? He has a treatment he wants me to add through the thermostat to repair porosity issues related to sand castings. He also stated he would take it to a special xray equipment, if necessary.

No idea. This is a learning curve for me.

My Electrical problem is solved. Huge thx to JT for all the help.

Bolt holes are separate from cooling passages.

I'd be leery of any "Treatment" you pour into the thermostat housing. More than likely said treatment is either block sealer or blue devil which is known for plugging radiators, heater cores, water control valves etc. I'd pull the head and have it checked before introducing any snake oil into my engine.

Good deal. Happy for you, Andy.

what did you find wrong?

what did you find wrong?

Main power wire contacts were loose at ammeter in cluster.

I am by no means an expert in this but I've read many 2F threads over the years and I don't recall porosity of the metal ever being cited as a cause for coolant loss. I think the machinist is unwilling to accept that he missed a crack in the head.

Find 2F.....check

Bolt 2F in......

Light cigar.....

Drive.

 

[jrob]

good deal Andy. JT, that problem sounds a little familiar?

 

[jrob]

Well we've made a little Progress on Srob's truck. Full hydro is plumbed, front shock mounts are in. Here are a few pics

 

[jrob]

A few more

Yep. Similar issue on your truck...except on yours it looked like someone had been roasting marshmallows on the back of the instrument cluster.

Dayum JRob! I thought y'all were just drinkin beer and tinkering...

Looks badass. Can't wait to watch it flex.

 

[Fireman]

Looks bad ass! Yall are doing some great work.

 

[wct49]

@jrob does not tinker.

 

[Bodean]

When I'm there I do a lot of beer drinkin' and tinkling!

I'm in total awe of the level of work turned out by Florence Hybrids!
