So I'm considering going in a whole new direction and want to know what my existing motor/trans/accessories would be worth. If I do this I really want to make it a one or two item sale and have it over with,,, here is what I got
455 F .060 over rebuilt by 4 star engines in Kansas, K heads completely gone through (receipts over $836) Erson cam part #E540000 grind VK100H, Cloyes double roller gear and chain, hooker 3902 headers. Professionally rebuilt Q jet on top Edelbrock RPM intake. Not sure of engine mileage other than top end listed parts less that 2000 miles.
2004r trans with trans go kit, had trans since 2003 maybe 4000 miles. Converter was new then as well as B&M lock up control.
Would want to sell complete engine trans combo to include AC compressor, PS, Alternator, from factory fan to drive shaft, oil pan to carb.... Everything runs great and I got 14.2 mpg 2 weeks ago doing 80mph over 200 miles. I don't race so nothing has been abused.
This is a long post but not near as long as my proposed project,,, I got receipts for most of it, so the question is..... What's it all worth? Inputs?
