Hey Mike, I've been meaning to ask you, is that a custom STB? Or is it a KB piece?

It is a Kenny Brown.

This is just an estimate but:

Engine: 2900.00
Cobra Intake: 490.00
Mustang Valve Covers: 20.00 on ebay
Polishing: Did it myself.
24 lb injectors: 220.00
JBA headers: 571.00
Pro-M MAF: 218.65
BBK TB: 258.00
SCT chip: 350.00

HP with stock motor and intake: 150
HP now: 196

Just so you know, you can unbolt the throttle plate and slide the shaft and linkage out of it to put the return spring on.

nearly went that route, but all I was doing was rounding out the screwdriver slots. Wasnt budging.

Ah yes, very common problem. Since I do that as a side job (halfshafting and porting tb's) I invested in a hand impact tool made by craftsman. You hammer it and it twists. Pretty nifty, and well worth the 30 bucks.

ah, good to know. BTW, I've always wondered... what the heck is halfshafting anyway?

 

[Thomas]

And now I also incorporate counter-sunk screws on the throttle plate to open up the pinch point even more. But thats the main idea. It's literally halving the shaft.

all this mods and you run a 15.........not trying to offend you but i was thinking of swapping my SC engine for a 5.0, but i dont think its such a good idea anymore.

 

[MaddMartigan]

If you are going from a 3.8SC to a fairly simple 5.0 then it is definitely a waste of time. If you are going to go to a 5.0 base then go with a 331 or 347 stroker and build it to leave room for a supercharger and you can see unreal power. If you want to go carbed then consider a 392 or 427 (351W base) and customize it all you want.

I dont know that it's a waste of time, I believe it was xr7 dave who bought a project sc and converted it to 5.0 just for a new project.

I don't know why MIke is only running 15.88, maybe it's an old time, but a local guy ehre with 2" true dual straight pipe (done by previous owner) and cobra intakes ran a 15.8, so I'd say something is not right, or it could be the location/altitude/weather affecting it, who knows.

Well, if you are doing a stock for stock swap it is a waste of time. You lose performance because the stock 5.0 didn't come with as much power as the 3.8SC.

It is a good base though. If you are going to change the heads and build up the top end along with a decent bottom end then you can have something special. Keep the compression reasonable and supercharge it and you can have something special.

 

[Mike Donley]

I am sorry if I disappointed anyone, but I built the engine for car shows at first, not speed. i needed a new engine and wanted something with a little extra power, but until I met the guys in the Bama Mafia, I had no desire to race or go fast. I did not do anything to the heads or intake. Also that time was before I had the SCT chip, and also was the FIRST time I ever ran down a track. It was also mega-HOT that summer day here in Alabama and high humidity. I am planning on running the car again sometime this month or next. when it will be cooler. I also still have the factory exhaust piping around the gas tank, but I have the '92-up fuel tank to swap out so I can put true duals.

I found out a few months ago that my rear brakes were totally shot and had cocked in the drums. They were dragging really bad and this could have contributed to my slow times. I had to completely replace every component of the rear brakes.

Right now I don't have the money to buy go fast stuff like heads and gears, so I concentrate on looks. It goes fast enough for me right now.

How does that fit under the stock hood?

Who is your question directed at?

It fits under the hood if the insulation is removed and a chunk of the bracing is cut out.

Well i think if Best thing about the 5.0L ARE:

No crank sensor to fail
No Crank pulley bolt to break
No Blown Headgaskets
No Nose cone bearings to fail

:tongue:

 

[jk69cat]

mike i need to do that on mine for hood clearance. which brace? the one on the left?

The reinforcement is sort of 2 levels Cut out the rearward part and leave the front part.

bingo

 

[jk69cat]

thanks, thats what i needed . i hate to loose the hood blanket. but i could just cut it out around it. it looks like it was a pretty easy modification.

I think you could re-install .

I gues you could reinstall it after cutting the
reinforcement without cutting the hood blanket
