how much with this combo - Pirate4x4.Com : 4x4 and Off-Road Forum

Built not bought · 11-02-2011, 05:19 PM

I got a 302 block from a 97 explorer. (roller motor)

gt40p heads
f303 cam
bbk shorty headers
summit carb intake (edelbrock knockoff)
holley 650

What do yall think power wise it is making or is there some other cam I can run to make more power with changing the heads?

Seams like alot to me but i cant say for sure a stock 97 5.0 is rated 215 crank hp and all you adding really is a cam.
I would keep the efi also just my .02 cent

fordtrucknut77 · 11-02-2011, 05:42 PM

X2 on keeping the efi what is it going in anyway? what will it be used for? I have seen instances of actually losing power by taking efi off and installing a carb.

blown95svt · 11-02-2011, 05:45 PM

Ya but the explorer cams really kill any kind of power. I've seem a couple Efi combos in mustangs with stock explorer motor with custom cam and full exhaust lay down 301/300

Explorer cam is weak i know i have a 5.0 out of a 96.
Whats it going in?
If anyone else has opinions i would like to hear also, seams like most time these 302 with gt heads cam and exhaust are around 250 from what ive read/remembered

Bingo. With conservative timing too. With the p heads and that setup you may be able to toss a lil more timing at it and get a lil better but be stuck running 91.

With that cam I'd get a set of 1.7 rockers too. I ran simular setup in a Volvo that had a 97 sploader motor. But I had 2 turbos hooked to it and efi.

How would you bump timing on a coil pack motor never done it before considering he uses the coil packs?

He will have to put a dizzy in it. I was running megasquirt standalone ECM that controlled the Edis.

Ford rules · 11-02-2011, 06:28 PM

Okay thats what i assumed^
What does Edis stand for?

dieselboy740 · 11-02-2011, 06:36 PM

Eletronic distribution ignition system iirc.

It uses a 36-1 wheel on the crank to tell the ECM where it's at and it decodes that signal and fires the coil packs. They are actually a wasted spark setup. It always fires 2 cylinders at once. One on the compression the other on the exhaust strokes.

Ford rules · 11-02-2011, 06:41 PM

Okay figured it stood for something like that.
Yes i figured out the wasted spark setup when i mixed up the plug wires but it still ran fine did some research and found that its the wasted spark setup.

This combo is actually for a mustang as a test bed for what I want to do for my ranger. The efi stuff was gone when I got the motor and carb is easier since I dont wanna have to have chips burned and so fourth.

I will test this alot for my ranger and seeing from there.

Someone said adding a 1 inch carb spacer will pick up 5 to 25 hp and more tq also. Is this true?

Do yourself a favor and sell that f-cam and get a custom
Cam made. It's worth the extra money. Unless your set on that cam. The alphabet cams are better than stock but there is a lot more to gain from a custom.

who can I get one from and how much are they?

I use hitech, they are around 300$ there are other companies. On my 95 I gained 47 hp swapping a custom in for a off the shelf comp blower cam. They make the cam for your car! They ask ya a million questions and design one for ya.

Built not bought · 11-02-2011, 08:12 PM

so you had a aftermarket cam and went to a custom cam and picked up 47 over the aftermarket wow!!!

That would put me over 300 for sure

Well that was in my supercharged 331 with big heads and intake. But you will
Def gain more than a f cam.

Well shoot Im kinda lost on this thing and what should be done motor wise with it.

cyclegrip · 11-03-2011, 07:14 AM

Is this also true for stock truck motors?

The engine the He was asking about is a roller cam short block and also cam
Stock with the good gt40 heads. So for a truck to be simalar you would need to
Convert it to roller cam and get a good one, get some decent heads, decent intake, exhaust and yes it would be comparable.
