Well, wish me luck.


With the help of the wiring diagrams posted here, and some of the advice, we are going to try to make the 302 live today.


We picked up some BBK shorty headers yesterday, which was the last piece needed.


Should be quite the beast. Stock, it's rated to ~175HP stock/~270TQ, but with the intake manifold we have, some carb spacers, good tuning, and headers, we are hoping to be around 200-220HP/300TQ.


Anyone want to shoot me their number so I can pick your brain if I get into a bind?

it's automatic.

If it is an '85, it is 205 or 210 horse. The earlier2 bbl versions were 175 or so. The motors are amazingly torquey for a short stroke push rod motor.

Let us know if you get it lot off.

Yes its good to -know a guy




as long as its not over $25

I hear he drives it to the bank to cash his Social Security check.

Okay I got a little more info on the '85. The wiki info does not match what I remember from when I bought mine, but their HP numbers are probably correct. They show 175 for the year two precious, 210 for the '85 and 205 for the '86.

Here's how I remember the story as told in a series of car mags at the time. I didn't have the Internet then for more info.

I remembered the mags saying that the late '85's got the roller cam. Wiki says that only the manual transmission cars got it. The '85 also got a four barrel, wiki says it was a revised four barrel but I remember the 5.0's having two barrels for a few years before. The '85 got stainless factory shorty headers. They weren't great, but they flowed better than the cast units. The '85's also got double roller timing chains and forged pistons. Mine slapped a little when cold making me believe the forged piston claim.

They had planned to carry the engine over to '86, but they got nailed for emissions violations and rushed the injection into production for the '86 model. They sold lots of the '85 engines as crate motors. The injection system did not flow as well as the Holley which was responsible for the 5HP loss in the '86 model year.

All this makes a roller cam '85 model quite unique. The only year of the roller cam AND The Holley AND the last year before the Siamese bores. At the time I expected to see lots of problems arise for the Siamese bores of the '86 and later cars, but they worked out surprisingly well.

Oh yeah, another thing, there was no different cam grind to take advantage of the roller followers. The gain was less friction drag decreasing parasitic cam drive losses and as anyone who has ever fooled with a roller cam knows, lower oil temperature. I didn't keep my GT long enough to reach rebuild time, but I already planned to use a cam grind that would take advantage of the rollers. You can get significant gains with a grind specifically designed for the rollers and still retain good idle and possibly a slight increase in fuel economy under certain conditions.

Let us know how this gem works out.

I think of this....

Yeah, but the family trickster never had a motor like the '86 GT. JIM SHOULD GET AMBITIOUS AND BUID A FAMILY TRUCKSTER OUT OF HIS. I'LL BET. IT WOULD BE A HIT AT A LOCAL CAR SHOW.

The easiest thing to do for an ignition system is use a GM HEI ignition module. They work really well and don't require a resistor to the ignition coil so you can just run straight 12 volts from a relay or key switch, you can use the distributor the engine came with and they are very small. Durasparks are sometimes unreliable bulky things.

idk why everyone wants you to ditch the duraspark!? its such a simple and reliable system . if your dead set on dropping cash, go full msd. msd dizzy, msd6al2, blaster coil, and plug wires. should be all you need.

not sure what your plans are, but you can buy duraspark parts at any parts store, good luck in a small town when you need a msd part.

I totally agree. Back in the day I went through a number of dura spark vehicles and never, ever had the least bit of trouble. I even have two vehicles still on the place with them. A 64 Galaxie with a retrofitted DSII and a 78 F150 4x4 that I bought new and am in the process of restoring. It still has the module in place and untouched, that Henry's boys mounted on there in September 77.

So some of these units have failed? Let me see, they have used millions of them as far back as the mid seventies and some of them have failed? I'm shocked!

I hate to shock anyone, but HEI's fail also as do every other electronic ignition system.

Anyway kmay makes a great point in that IF you have a failure, what you need to get on the road again, is never farther away than the nearest auto supply.

The reason I convert cars to HEI is because its easier in some cases and the system works well. Duraspark requires a resistor to control current through the coil. HEI just varies the dwell to control current eliminating the need for a resistor which in a lot of cars is not there and just one more part to install. Lots of manufacturers copied the GM system for a reason. It works well.

How does varying dwell time effect primary ignition Ampere value? Which mfgs copied HEI?

Well, it's sorta in the car.

Ran into some problems, but got most of them figured out.

Working out the mounting today, and once that is complete, it will be the long process of making her work.
