can 081 heads be used effectively on a daily driver? most ive read say the compression is to high for a DD.

 

Mine runs nicely, passed emissions out here in AZ, tuned and have about 30k on
the crank since I put the motor in. If anything, shes eats alittle more gas then the
factory build iirc. There was a few minor issues in the beginning, getting
it tuned solved a good sum of that.

Daily driver wise, my commute was a 28mile highway haul each way.

I like em!

 

what was MPGs before and after the tune?

 

It was very lean, I had a narly ping uptop initially, so I kept it below 3500rpm
during that time. Symptom of not enough fuel, and a single pattern cam more
so than the head choice. Id say it was no worse than 16mpg. After the tune, I
could run her like normal but, it was still around the same neighborhood 18-20.

I got plans for the heads but, no time to work 'em over!

If only I kept the factory l98 cam I could tell you exactly how
it'd run in conjunction with the 081's. Are you staying with the
factory cam?

 

no im going to be using a crane 2032. biggest i can go w/ to stay w/ factory ECM settings.

 

Right on, Should be a nice ride when it is said and done. You wont get that much of
a gain in compression as some people think but, I noticed it. They flow decent,
and even better with a good port and bigger valves, which is a must if going on a 350.
Very streetable though, and great to learn/play around on without worrying about
the monetary value of em too much.

Especially if it is your first time porting. You've seen the 305 head article by
Sitting Bull right? Great visuals to be seen if your going that route.

 

no i havent seen that article by Sitting Bull.

If she does run good and she dont ping uptop then sweet. But, I wouldnt
invest too much cash in them as there are better options out there for TPI
setup.

still cool to know what you can do on a budget!

 

SWEET article! hopefully i will be getting a set of 081s ported/modded here soon. im going to need a tune since i will be removing the AIR system and possibly the EGR. will be using 24# injectors, hooker 2055s w/ full exhaust to tips, new base, AS&m LTR, and will be porting the plenum.

 

I knew you'd dig it.

It inspired me when I first came about the forums. Notice that date
of 2001! Hell I wasnt even registered then, but I did enjoy this thread.

Just keep your eye on the detonation, get it tuned pronto especially
if going with the 24 pounders. and, by tune I dont mean learn how to
burn proms yourself... Good shops still work OBDI, just takes alittle
homework to find them.

Ignore all that if you got a shop already.

 

how bad was the detonation you had? did the tune take care of it?

 

To be precise, 3/4 throttle/WOT in overdrive mostly. Like I said a lean
condition at operating temperature contributed to it more so than anything.
Just take into consideration the heads/valves in stock form sitting on a bigger
bore. Anything not operating they way it should (like a lean condition) can
potentially provoke the situation.

 

what did you do to eliminate the detonation?

 

The shop upped the injector bin in the PROM, no more white spark plugs for me.

 

what did your build consist of w/ the 081s?

 

what was the bin changed to? so i know when i get the car tuned.

 

Pretty basic really. Mild port TPI, 24lb ford injectors, the single pattern
hydraulic roller, cant recall exact specs, cam card is around somewhere.
The numbers I listed were not correct. Hedman 1 5/8th shorties w/ AIR.
That's bout it engine related, built to get me to work after I spun a bearing
back then. Behaves nice on the road, a classy ride I like to say.

 

I dont know the value off hand, that was quite awhile ago.

 

i hope to be getting a set of 081s ported w/ comp springs, using a crane 104224(214 .452/.465) 112 LSA, may use 1.6 rr's to give it a .482/.496. hooker 2055s w/o AIR, EGR delete(maybe), accel super ram base, AS&M LTR, hooker CATback off a magnaflow hi-flo CAT, ported plenum and 24# injs, and AFPR.

 

Im jealous! Especially with your suspension mods listed in your sig.
I chose to keep the AIR/EGR system functional, as it is more of
my commuter more so than a street pounder.

Like the Sitting Bull article mentioned, if you work those heads the
right way, they flow far better than what they are worth in terms
of money.

 

im hoping for a SWEET sleeper street car when im done. nothing super crazy. something to take out a few more ricers and tangle w/ a few of the 4th gens that run around here.

build wont be done till i get home in Aug., but ill post up #'s when im finished.

 

Hopefully it pans out nice, you a Sailor by chance?

 

hope so too first time ill be putting 305 heads on a 350. so i need all the input i can get.

im a seabee actually.

 

My goodness, who woulda thought!

Kinda off subject, im working on going diver at the moment..
So, I got a kick out of that. Got a AE buddy serving with the
stennis, hes got a killer ride as well, haha!

As for the 081/416's on a 350, the path is well traveled.
Itll work, how well it runs initially is anyones guess.. Im
going out on a limb here, but guessing that you'll like them.

 

so i guess your in the navy as well?

i hope w/ the dual pattern cam i will not have the detonation issue you had.

 

In the enlistment process actually, Im still a tad young.. hehe!
Though I should have been in at 18 if you get my drift.

Its not so much cam choice as it was running condition for
my issue, seems your 2032 is a reasonable cam. Also, my ping
was only at operating temp/closed loop in OD, not like it was
prevalent everywhere I went.

 

what you mean by running condition? was it the bigger injectors running the stock bin?

 

What I meant was. The car never detonated when cold, it was always
in closed loop. So, when the ECM had command of the engine is where
my problem started. Car was likely going lean to rich in a insufficient manner
and so forth.. ECM adjustments were erratic.. I didnt tune it so Im not
entirely sure.

My first thought converter lockup was giving me the guff, as it
only would ping under 3/4 load in OD. But, nope ..wasted time
screwing around looking for something that wasnt the problem.

 

hmm sounds like w/ the larger injectors may have been your problem.

 

But, with white plugs ..Im inclined to say it was starving for fuel.

Then again, it could have been rich during a certain load speed
and super lean at another. Hence, why setting the proper injector
bin value is vital when adding larger or even smaller injectors, a AFPR
alone is a crude way to regulate fuel delivery.

Shes gotta be smooth, especially with the higher compression
over factory and stock valves of the 081's.

 

if it was starving i would tend to think it wouldnt detonate.

 

Imagine how hot it gets though, valves are gunna chatter
if your redlining the beast, even fumes light up like a dry
bush prematurely, which is what ping is.. spark knock/premature detonation.

I also noticed the car likes 87 octane more so than 91,
anomaly? Im not sure, I wont argue with cheaper gas.

 

well it looks like the deal i got for the heads is going to go through. ive been considering using a thicker head gasket to bring the CR down a bit to hopefully avoid any problems.

regardless its getting a dyno tune...

 

Congrats, hope you got a bargain!

Please let the board know how you made out with the combo,
As you might see, the topic has come up quite a bit the last few days!

 

i will build wont start till Aug. since i am deployed right now.

 

Keep 'dem sealegs fresh for her!

 

ive been talking w/ southbay about some injectors and they have recommended a 27# inj. i was planning on going w/ a 24#.

in your guys experience and from what i listed above as the mods going to be used, which would be a better selection?

they guessed i would be pushing 350-400 HP and i thought that sounded like quite a high number for my planned mods. even for @ the flywheel...

 

A 350 will be able to use the fuel, and with it tuned it should be good.
I know a few guys run 30# on a n/a TPI motor, I think it is pretty smart
considering if you change something, youll have enough injector for whatever.

Ive hear some guys kick themselves because they bought 24#
but figured out down the road 30's would have been the best bet.

With the 10:5:1 compression, the 2032 cam, and you work those 081's,
I would imagine you getting roughly 300BHP with a ported/aftermarket
tuned port. I dont foresee a problem with 27# on your engine!

You guys agree?

 

300BWHP sounds like alot to me. i didnt think this set up would get me into those numbers. dont get me wrong im not complaining.

need to make sure of the correct injectors dont want to have to buy 2 sets.

anyone else have and opinion???????????

 

Oh, I meant base horse at the crank! Id like to think around
265-275 at the wheels give or take, mine feels stronger than stock
by a good portion.. with unworked heads!

and yes please, someone with some injector experience chime in here!
I really cant argree or disagree w/ southbay with confidence on the
27#er's.

After rereading the thread, an AS&M LTR MAF TPI setup, crane 2032, ported 081's,
tuned with a nice exhaust would produce better numbers than factory id hope!

Sheesh, I want your car.

 

come back safe. when i saw your CM i thought you were a commander but now i see its construction mechanic. that means part time you are blue water and the other part you are boots in the dirt. take care - cant wait so see your build.

 

more like full time boots in the dirt, a dirt sailor i like to say.

i cant wait to get home and start the build! i know my numbers will be better than stock. porting the plenum to the AS&Ms, porting the Accel base to the AS&Ms, w/ massively ported 081s, Crane 2032 cam, 1.6 Pro-comp full rollers, Hooker 2055s w/ hi-flo Magnaflow CAT, and a Hooker CAT-back on a fresh bottom end rebuild better get me alot better numbers than stock, w/ hopefully a dyno tune but a chip tune none the less.

not sure about 300 bwhp though, it'd be nice though.

still need opinions on the 27#ers...

 

just got an email form southbay. they are recommending 30#ers now since i will be running a AFPR. not saying they are wrong, i just dont want to buy what i dont need.

anyone else got any insight on this.

 

Anyone with any opinions at all about the 27 or 30 pounders?

 

hope someone can help me out.

 

really need some help here guys!!

 

I dunno man, since nobody chimed in.. The most prudent move is sticking
with the 24's. The 30's just seem to be a little excessive for a daily driver.

Youll be driving it at moderate RPM so, I dont see a substantial benefit.

 

i thought the 30s were kinda big for a DD. i may go w/ the 27s. im still waiting on an email back from them.

i dont know if the car will run well enough on the stockers to get a good dyno tune. they were asking for a HP number to accuratly recommend a set.

 

i dont know why you guys are running that much injector...... i built a completely new hotcammed 355 forged engine and im running 24 pounders with an afpr of course....

 

not running any injector yet trying to find the correct one. the 27# and above where recommendations from southbay.
