ATTN: 351 Guru's.... need help
 

ok, my 302 has had it, when it gets warm the oil press needle on the gauge drops off at idle and then picks back up when its it reved.... It also has a broken headbolt, so I found a 351 from an 83 f150 that is carbed and I am gonna rebuild it (maybe a 408, havent decided yet), get a lightning lower intake manifold so I can still use my cobra upper intake, swap it over to fuel injected, put some RHS Pro Action 200cc heads on it, and possibly run nitrous on it.

Here are my questions...

If I swap over to EFI, I should still be able to run my A9L ECU on this right?

I know how to calculate Fuel Injectors, I have #24 right now with a C&L MAF and that is only good top around 350 HP right? I want 400-425 so 30# should do the trick right?

I know this isnt a roller motor, Does anyone make a retro fit roller cam setup for this motor? If so, where do I find it? <--- Info that is needed the most

I know about the oil pan and pickup tube, and I am gonna swap to aAJE Racingk-member too, but is there anything else I am forgeting?

RE: ATTN: 351 Guru's.... need help
 

200cc RHS's are good for a 351W ......... just ordered some myself.

for a 408W you will need the 215 RHS's or AFR 205's and it will make over
500hp or 400rwhp

You can use you A9L computer with an SCT tune, but might take some
time and head scratching to get it just right.
I'm about to go with the AEM plug n play system myself, after all the
back and forth dyno tune sessions getting everything just right wish
I had gotten one to start with.

You can use roller cams if you get the $400-500 linked covnersion roller lifters.

my 351W runs ok on 24's but gets real lean at upper rpms
30-36's would be good.

you need couple of other small things for swap like new flywheel
and spacer for crank pulley to line up and a/c - p/s bracket and 351 dizzy
and lifted hood for clearance ( took a 4" to clear my Trickflow EFI intake )

$1600 for an AEM r.barn???? why not a megasquirt?

RE: ATTN: 351 Guru's.... need help
 

AEM does SOOOOOOO MUCH more, and no need for assembly or "adaptor" boards

I'm going to drop my entire MAF system with it and go to BAP sensor and dual wide bands.
It will controll the boost level for my turbo thats about to go on
Data log
Download predone tune maps from other users on their web site.
dual rev limiters
acceleration controlled traction control.
more and more

very nice system that plugs right into factory harness, sky is the limit on
adjustable parameters.

RE: ATTN: 351 Guru's.... need help
 

hrm... funny.. Megasquirt does all that as well


Looks like you shouldnt talk crap about systems you know nothing about

RE: ATTN: 351 Guru's.... need help
 

Adder since you know so much about megasquirt maybe you can compare and contrast the 2, start another thread if neccesary but I would like to see why one is better than the other

RE: ATTN: 351 Guru's.... need help
 

$500 > $1600

Dont remember saying anything bad, but if you want me to .....................

How many hours putting it together did it take???????????
How many wire splices and "adaptor" boards did it take?????????
What kind of warranty does it come with?????????
How many aux. inputs does it have????????
Will it monitor EGT's??????????
How many aux outputs does it have ??????????? AEM has 16!!!!!!
Will it control boost????????
Will it control nitrous?????????
Soft cut rev limter?????????
Knock sensor provision????????
Will it auto fuel map with wide band O2's?????


You're wack, AEM does twice as much and is twice as expandable
to control all kinds systems from a/c and fan to boost or nitrous with
all kinds of triggers from TPS to rpm's

Yes, it cost a lot but its not some do it youself Hobby kit either.
It installs in 2mins and comes with 1 year warranty.

wow thats the kind of description i was looking for....but im still torn here

The price is high, and you dont get that self accomplishment feeling and you dont really learn how it actually works by not being the one to put it together
however it does offer alot more and the 1 year warranty is a plus

RE: ATTN: 351 Guru's.... need help
 

Just wait till the microsquirt comes out... youll all be jealous then!

RE: ATTN: 351 Guru's.... need help
 

So R. Barn, are you running a roller or non roller motor?

RE: ATTN: 351 Guru's.... need help
 

I do have a 1994 roller cam block, so I could use standard roller lifters
and hold down plate

RE: ATTN: 351 Guru's.... need help
 

So you are or you aren't? Or am I going to have to go look up your previous posts and search for it

RE: ATTN: 351 Guru's.... need help
 

i'd run a solid set-up...mega squirt is very good...i chose pms for my personal taste reasons...mega is 400 bucks cheaper than mine,but it's what you like i guess

RE: ATTN: 351 Guru's.... need help
 

i have a question why cant you just drop a set of roller lifters in an older block?

RE: ATTN: 351 Guru's.... need help
 

I want to run a roller set up for many different reasons... Less internal friction = more external power, plus a roller cam allows you to run stiffer valve springs for higher lift cams. Not to mention a roller motor can rev higher safely. But I can grab this 83 motor so cheap ($150),But on the other handI found a reman 351 roller motor shortblock thats 3 hours away from my doorstep, but it has Keith Black Silvolite pistons in it and I heard those are crappy and cheaperthan hyper pistons... This motor is a complete shortblock for $899 so I dont exactly know what todo.

RE: ATTN: 351 Guru's.... need help
 

Since things got a little off topic...

Yes, the A9L will work, but a custom tune will get you better drivability and more power.
The wilder the cam and the larger the injectors, the more likely you are to need a tune.

I ran my 408w on 30's for a while. The 30's were ok until I shortened the PW to only fire when only the intake was open.
36 would work well.

There are 2 options for getting hyd rollers in your block.
1) A reduced base circle cam
2) A set of 351w conversion hyd roller lifters.

Option 2 is greatly preferred as the reduced base cams can introduce some valve train issues.
The conversion (link bar) lifters are $475 from Crane.

I have a bunch of swap info on my site; listed in my sig.

RE: ATTN: 351 Guru's.... need help
 

The block has to machined for roller lifters or you have to buy and Expensive roller lifter set up... You can but its cheaper to get a block thats made for roller lifters.

RE: ATTN: 351 Guru's.... need help
 

Ok when?

Depends if you did it yourself or if you buy it assembled, assembled it takes longer to get to the stock EEC than to install the Megasquirt using my adaptor board.

No splices, and just one "Adaptor board" which is not as big a deal as you make out.

Most vendors warrantee a prebuilt Megasquirt for 90 days, butyou get free lifetime support. if youhave a problem with one of my boards, I'll fix it for free.

Inputs? like for what? Nitrous? Yes. Table switching? Yes. Flex fuel? Yes. Knock? Yes. An input to turn on your mood lighting....ah.....No.

Yes.

How many aux outputs do you need 4? 16? 32? Please explain what you need 16 more outputs for anyway?

Yes. PWM real time boost control.

Yes. Dry or wet N2O. There's even a seperate VE table for nitrous.

Two stage soft rev. programmable to any RPM you want.

Yes. Fully programmable limits and timing adjustability.

Megasquirt has AFR tables that work wth EGO correction for any wideband. Autotune with a laptopor with Automatic Mixture control.

Yep, Were Wack. Butwe know how it works,We can mod the publically available firmware to do practically anything andthere are multiple tuning interfaces which can be DL'ed for free. Upgrades to the firmware thatprovide more functionality? Free!!

I can turn on/off my fans anywayI want to.

You need to read up on how yourEEC works. It doesn't "control"the A/C, but rather itcan disable the A/C ifneed be, Oh,I can do this with Megasquirt also, from any parameterI choose.

Not neccesarily true. Youcan buildMegasquirt yourself ifYOU want to, but you don't have to.

By the way, my EEC Adaptor board works with ANY EMS, not just Megasquirt.

Megasquirt is universal, you can run it in your Lawnmower, or in your Ferrari, in fact Megasquirt has been used in both, Yes even Mustangs with V8, V6 or 4cyl.It's not specifically designed to work with your Ford, that's part of what the adaptor board does.I have a Megasquirt based single box Ford PNP system coming out soon, but probably won't be available until around the end of summer.
