rear shocks info wanted

HEY FABO FAMILY, hope all has been good , ive been mia for a bit.
Spring is here soon I think lol some beg to diff. My car is ready to ROCK 10k in new motor and trans ,and other goodies . Now 1 more thing to address .I need to get the rear end up higher for bigger tires . I dont like air shocks .
So my car is a 1965 Barracuda with a 400+hp built L A 360 with a tsi 3 speed auto and 8 3/4 sure grip my old tire size was ok at best , but now I would like to go 28x9.5 or 26 at least ,so I need to get the cheapest , but most efficient and strongest way to pick the body of the car about 3-4 "s to fit the tires under the car and still plant the tires in the road. new leafs and cal-trac set up is out of budget at this point ,and the car value is way past what some 1 might pay for just 3/4s what I have in it though selling is not an option .
Ive owned the car 37 years ,and plan on keeping it 37 more .
So I need traction and stance , there are some awesome cars we all own in FABO but this is an early A body so it needs shocks O to O ,or mabee a really strong shackle lift + shocks. a stock 65 Barracuda shock is 21 1/2 fully opend and mine settle around 18" with a firm , not too stiff ride and a fair plant.
Please feel free for options with a $300.00 budget but strong lift , with good ride yet great weight transfer and traction ,I have $900.00 and need new M/T tires and 15" rims . please share your thoughts and those awesome pictures of your cars . Show us your stance .
Lets have fun BUT stay SAFE
