Probably in my red car. I had that AOD trans in two different cars. Three different converters in total.

WIsh you would have, thanks. It was fun, and ran good for being built by someone "dumb"
Thats right, i forgot you had the red car back then.
I think the guy who has my car said he would take 9K for it now. Same power train, but went to Team Z to finish up the cage, and redo the whole rear suspension. And it's now painted the new metallic red on the new Explorers.

You're not helping my wallet or my cast pistons out here! I've got a buddy who has been trying to convince me for a few years now to just "try" a small shot on the car. I'm sure I would just try it.

HAHAHA i drove my car around with the bottle in/on....it's a blast. Cast piston can take 100 shot with the right tune all day, i sprayed a cast picton 351 for a while with 150...lol

Well I've read every post and TRULY appreciate ALL the information.
But this begs the question.
Instead of doing a 347 (which I think sounds cool) with GT40p heads (sitting on the shelf). Would I be better sticking with my 302, adding better heads, (ditch the GT40p's and getting one of the recommended ones in this thread) leaving the bottom end alone (stock but rebuilt)?
The parts I have to work with are:
- Built AOD trans with 2800-3200 stall. (I know the car it was in and it held up no problem to a 347 with Roots blower and spray, in a car show car, not race car).
- Holley 650 Dbl Pumper (NIB) (exchanged the Street avenger 570)
- Edlebrock Performer intake
Remember its not a racecar, but a cruiser that my wife will want to drive occasionally.

Going with a rebuild and freshening it up with a .030 bore won't hurt. That's what makes a 306ci motor. If it were me I'd save the $$$ on the stroker for what you want and do a nice reliable bottom end with stock cubes but with a good set of heads like you said.
The carb you have is fine - I am running a Holley 650 as well.

This all the way. If you were looking for a 10 second time slip on motor, i would say stroke it. But if i were you, rebuild the bottom end, maybe go .030 over if you need to. Buy one of the smaller 165 class heads and a nice cam and rock it. You will have a ton of USEABLE torque (something needed in a street car) not have to turn it hard and it will be a blast to drive and won't be unmanageable. Like i said i had no issues letting my escort driving wife drive my stang. And it will even do half way decent on gas. The SVO GT 40 X and Y heads are great for what you're doing and can usually be found ready to go for around 750. Or the performers. Matched with an 1 5/8 long tube header and nice 2 1/2 exhaust and an RPM Air gap intake you will be suprised. If you have the time and money, have the intake matched to the heads, it makes a decent difference, and that intake out of the box is smaller than most aftermarket head ports...heck so is the victor junior. To me it's well worth the money to have the intake touched up at the last few inches of runner to match the head, but definately not necisarry.

I've had both, a stock bottom end 302 which had canfield heads and trick flow cam, and also a 347 with z cam and tfs heads, the 347 was a great street motor, pump gas and went 11 teens on motor even in 100* weather, 302 went 11.94 on motor, got both in the 9's on spray, I can tell you from experience, for driving on the street minus the nitrous the 347 was 10 times more fun, stab the gas in high gear and spin the tires, the 302 was fun also, but it didn't come to life until you revved it high....its all in what you want, but like others have said, regardless of what you do I would upgrade cylinder heads, and I reccomend trick flows came for the money, they sound great and work good, and the best part is their cheap....have fun!

I have a complete 351w, oil pan to heads. its all stock and needs the crank turned. I need it out of my garage as I'm running out of room trying to fit everything from a 3 1/2 car garage into a two car sucks. btw I also have a cam for the motor that would be a good lil street cam. block is a 86 truck block so its non roller, cam is non roller.
$150.00 bucks and you can have all of it and whatever else I can manage to con you into getting out of my way.

WIth your 302 with canfields: this is why i stress the smaller head. those canfields are a pretty big head, and that's why you had to turn it to be fun. It's all about teh combination. Can't just throw any old head and cam in a motor and expect it to be a rocket. My guess is you thought the 347 was more fun is because you were used to wanting to have a faster car. Keep in mind he's looking for a fun cruiser that isn;t a slouch.
Tons of good ideas in here though.

I didn't turn it real high, roughly 6200-6500, I'm just saying it didn't put you in the seat until it git above 4500 rpm, and I think the heads worked fine, a little big, probably, but 11.94 out of an auto in a 3000 pound car with a stock bottom end is pretty decent....

Yup, that's what we got out of my buddies silver car at the same weight or more with his stock bottom 302 with teh TFS heads. But i always pulled on him till after teh 1/8th. My car 60' harder than his and was always faster light to light on the street, But in a full quarter his larger heads and much bigger cam ran me down, which is why i keep stating street car and useable torque for this type of application. Keep in mind he keeps stating street car. In a street car i always go for air speed in the combination to keep the torque curve low, and more fun/useable on the street.

I'm tossing the p's on the 302 with the intake and carb. I'll screw around with more power after I swap the stock 8" rear-end for something a little stronger. I am putting 4.10's in the rear, so it will be fun on the street with the torque from the P's.
Now what about a small shot of nitrous on a stock bottom end?
If it breaks, I'll just replace it. I have a 302 out of the '69 sitting on the shelf at my parent's house. I'd rather break the aftermarket block in the '66 (mid /80's block) then tamper with the original engine out of the '69.

69 Has cast pistons, you can safely hit it with 100-125. Some have gone higher, but i wouldnt' for longevity. For teh record i hit my on a regular basis with 175 on a factory non rebuilt high mileage 91 short block. 6 years and still running.
