I kind of see red when guys include the word budget and a hot rod engine build.
I coined a term.It's called a "open book build".
No budgets/no time limits.You collect the parts over as long as it takes when the funds are available.Then total when done what it cost.
Now if you budget yourself in a pile of trash parts,that isn't hot rodding.Where hot rodding is building the best.
So if you don't think your going to have the money or are not doing a "open book build"-
WELL THEN GO BOWLING.A BALL AND SHOES IS ALL YOU NEED.WALK AWAY FROM HOT RODDING AND DON'T LOOK BACK!!.
