Pro street

[68cougar]

I need some help, I need some advice on how to move the leaf springs inside the frame rails so we can put some big honkin tires on his truck. I figure to box the frame and swap the spring perches side to side. Any ideas or any links would be greatly appreciated.

How big do they have to be ? You can buy a 15x12 wheel with 7.5 backspace and run a large drag radial (315/60 or 65 I do not remember exactly which one my brother-in-law is running) or 29x15.5 Mickey and you only have to move the tubs . You can leave the leafs where they are . Any bigger and you will have to move the leafs inboard.

Frank,

Will this combo still tuck inside the outer fender edge for say a 6 or 7" drop ?

Thanks

A guy I know moved his springs inboard. He took the right spring and moved it to the left inside, and the left to the right inside, and boxed the frames. But he also narrowed his rear axle, If you don't narrow the axle the handling of the truck suffers.

[bigblock73]

Are you after looks or performance? You could run a quality traction devise such as Cal tracs and hook better than your stock suspension with fat tires.

I don't know about the OP Jeff, But I'm thinking more for looks. I'd like mine to look as good as it sounds, It would never see as much as a burn-out after sooo much time and money, Un-like someone I know....

i narrowed my rear end installed ladder bars coilover shocks now im running 31x 18.5 mickies

Hey, I resemble that remark!

[68cougar]

Im want big tires more for the looks. The truck has a good engine but by no means a super high horse power engine. I scored a narrowed rear end and 15x7 wheels for front and 15x14 for rear with 31x18.5 15 for the rear for $500. jjgmc do you have a pic of your rear suspension set up. Im looking for cheap, not afraid to put in the work but low on cash.

If the truck is slammed you may have to trim the inside of the fender lip a little to tuck the tire . I need to take pics of my in laws truck . It has a fact width 12 bolt with the wheels mentioned. We had to run a 5/16th inch spacer because of the heavy duty brakes hitting the backside of the Weld Draglites and that put it a little close to the wheelwell inner lips. If you had lighter duty brakes or at least drums without that big lip that hits that particuler wheel, you could get away without the spacers. If I can get to his house this week I will snap a pic. His truck is low. It has an upper case C-notch. The radiald bow off the wheel more than the Sportsmans and it is close to the wheelwells and close to the springs but it will clear.

Would appreciate that for sure Frank....

Thanks

That poor smallblock in the engine bay looks like a tricycle parked in a hanger.
You really need a big block if you want to pull the pro street thing off.

That all depends on how nasty the small block sounds !

You've heard the saying "Dynamite comes in small packages"

Ain't no N/A smallblock that'll shake the fenders like a 540 or bigger. Add spray or boost to a smallblock and it'll keep up....
right up 'till the mountain motor gets the same...then the real thunder will ring from the pipes!

Well my son and i are building this for his first ride. I dont think 800 horsepower is a good idea for someone learning to drive, much less the gas prices.

My buddies dad has a 327 that blows 454's/460's put of the water, And that is Muddin, Every one looks and says o easy win, then they get smoked, he does have 10000+ in the motor, custom heads but still its a Small Block smokin a Big Block.

Put the same 10G in a big block and you have an even coparison with the 327 you are referring to. I would like to see the winner then.

To each his own, they all have their place. Sometimes those little fellers wind tight and let 'er rip - in the right application a high revving horsepower type engine will take a torquey big block. But when it's torque that you need, cubes are where it's found.
I sure wouldn't give a kid a 800hp engine, a well built stroker would be ideal, though. We built one for my son's first truck, he has it in his second truck now. Plenty of power for a heavy truck but not a hotrod. It's amazing how well he treats this engine since he built it, he drives a lot like his old fart dad!

[monte0185]

Well the rule of thumb is there is no substitute for cubic inches but with that being said a buddy of mine runs an alchohol injected small block 400 pushing close to 1000hp last time we dyno'd it and ive only seen one big block that could come close to touching him running the 8th. He wont mention how much money he has tied up in it though. He can run the 1/4 in 8 flat hitting the rev limiter at 1000ft. I still like the sound of a well built big block though. LOL

[f.monroe]

I looked at my brother-in-laws truck today . There is 1/2-5/8" between the outside of the tire to the fender lip and at least an inch between the leaf springs and the inside of the tires. They are 15x12 Welds with 7.5" of backspace. The tires are 315/60/15 Mickey Thompson Drag Radials.
