Used car loan?

[Zefhix]

I need some advice or a referral to someone who might be able to answer my question here. A pretty amazing car just fell into my lap for sale that I never thought would be sold. It's a 95Z28 with a fresh, vortech-blown 383 LT1 to a modded t56 to a moser 12blt w/ strange axles. My question is because isn't stock, how do I about getting a loan for this car? It's being sold for well below what just the parts cost but isn't worth that on paper to a loan officer. My credit isn't an issue, just want to know if I should get the car appraised and then try for the loan based off appraisal or is there a co. that specializes in this sortof loan? any suggestions would be helpful....thanks.
