There are several things to sort before you get the rake where you want it.
- How low you want the car
- The look/theme for your car
- How much room you need inside the car
- The sort of rear end you plan to run (solid/independent)
- The engine & box combo (some are physically bigger than others
- The size of the body you are going to use
- What size wheels & tires you want on your car.
The engine needs to be set up pretty much level so the carbs arent working uphill/downhill, so thats a given.
As we dont have retailers who sell bucket kits down here, we get our engine & box on a low stand, mock up the front end with wheels on it and mock up the rear end with wheels and using anything we can (boxes, jacks, axle stands) mock the body in place.
Then we stand back with an adult beverage of choice and eyeball it all for ages and ages and tweak the boxes, jacks, axle stands till it looks right or till somebody brings more food or drink. This is a time consuming social event and not to be rushed.
Once it looks right, then its time to see if we can fit in it comfortably. Theres no point in having a bucket that isnt comfy when you are driving it.
I fit into very few buckets comfortably due to having a long back, big feet and a barrel shaped body. So I have a big bodied bucket, with a blown big block, big wheels & tires, a flat floor and a big rollcage. That way everything is in proportion.
I would love to have a lowslung bucket with a small body as I think they have better proportions, but theres no point if you cant fit into it comfortably.
You are fortunate in the USA to have good kits available to you. Most of them can have their rake altered by the choice of wheels & tires. Tell the manufacturer what you are looking for and they will set up the chassis accordingly.
