Australian ap6 wagon. Tunnel ram 360 with 4 speed.

here's another shot.

For a 11.50 and up ride, I would go with frame connectors, ladder bars to make full use of stock wheel wells. Will have to set the rear axle back about 3/4 inch.
Front would get a home made rack and pinion, coil over/spring combo with pass side shock tower layed over to fit TTI 67 up bb a body under chassis headers. I don't know if going with the rack and dumping the torsion bars give enough room for the headers, but plan to find out in the future. Those two moves open up a ton of space combined with a little shock tower surgery. The plan would be minimal shock tower move to keep the stock appearance theme as much as possible. Motor would be a 512 BB low deck, Indy dual plane with a juice cam and eddy heads. If you go conservative on the cam, it should stay in the mid elevens and idle like a kitten. Want more? Roll bar, head porting , looser converter and a big flat tappet and you are running 10.s Want 9.s? dump the dual plane for an x type intake, cage /dominater/roller.
Another route would be a hotter motor, no roll bar but a throttle stop to keep you at 11.50, but a mean mph!

Bigdad from what i have seen of your rides i know the real sleeper deal is out you will make it slick as heck. i personaly leave it looking as close as it does now the look on everyones face when you run it is priceless i would go with a small block block with a single 76 mm turbo with a 518 trans with a brake you can be creative in hideing a cage if its needed you can always make it look good when the sleeper thing gets old it would look good silver with red insides

There used to be one of those at Lebanon Valley that raced in super pro. Guy had a big hemi in it and he sat in the backseat! Man it was ugly,but it was FAST!! Let me see if I can dig up a pic of that thing.It was in a magazine a while back,some sort of famous racecar or something... Blue and Silver

maybe a new hemi with turbo and a 518 trans, I guess the motor could be close to stock and still make a LOT of power, but I don t know anything about these motors, just what I ve seen here... and I really like your car

Whatever you do, don't paint it.....SILVER!

Car is owned by a friend. Runs 11.20's.

What the........Who took the........You don't need advice on the grocery getter. You need to do something about the crime problem in your neighborhood first. Someone has stolen all the trees. Git y'all a trailer and git up here to Oregone and we'll git ya some trees to take home. We're given em all away to China and Japan, so you Texicans may as well git you some.

Keep it the sleaper look for stealth mode. Put in a moderate stroker smallblock making it run high 10's / low 11's.

Just make sure you install a towbar to bring you real racecar to the track
