Nick's "lvndpst" Restoration (and Slight Modification) Thread

Sorry to hear but I agree with your assessment. Try to make sure it isn’t something you are missing before tuning.

Can you describe the way it runs? Does it idle decently? Does it break apart through out the rpms or just have sluggish delayed acceleration? Are you sure there is no slipped intake gasket or other vacuum leaks?
I am with you on electronics I hate diagnostics but I’d start there.

well,...(and I don't know nothin bout the valve adjusting process on a stock 5.0) Your spec sheet called for a 6.700" length pushrod. When checking, it looks like the stock length is between 6.248, and 6.300"
do you have those comp gold rockers on these heads, and are your rockers fully adjustable?

The first thing I'd want to know is what is so different in your setup that you need a pushrod that is .400" longer than stock?
Not that that is causing you your problem this time, but when there is that much difference between stock and what you got, I'm just wondering why the diff?

The cam itself is purely a street cam, seems to have a decent amount of duration, and should be a little bit rough idle,....also, wondering what the stock ECU does when it has to deal with that.

What does a vacuum gauge tell you when the engine is idling?

If the setup was for a freakin carburetor, why did you change it? A carburetor isn't the end of the world,...it's been the way to fix phcked up frustrating EFI for years now. I'll tell you this:

If I had a 347 in the car, and was considering changing the thing back to stock because it's running bad,.what makes you so sure that a 5.0 stocker will run any different? Especially if you are running any of the stuff in the 347?

Let me see...........* The dilemma

Admit I can't/don't want to either fix what's wrong, and change the entire thing back to stock....

or.....

Put a carb on the 347.

" Uhhh Hello? Mr. Holley?....I need a 4776 please"

Maf? what the hell is that for? (8) 30 # injectors? sounds like a big waste of money. Stupid expensive F.I injection manifold?....What a way to make up the necessary fundage for the carb swap...Salt and pepper shakers? belongs on the kitchen table. Throttle body?,....maybe it'll be a cool piece of art to add to your bent flexplate table ornament..

If I had it all to do over, The whole MS2 thing would be still sitting on the shelf at DIY. A carb (or in my most recent iteration) carb(s) would be on the engine....It's an amazing little thingy that has been working with almost no changes for 100 years....It's still what allows restricted intake engines to make 800 HP in NASCAR, still the fuel metering choice of 99% of N/A drag racers, and would be what the Monster breathes through, If I'd had one minutes worth of trouble with the current setup.
