2015-2016 I built a stroked 390/447
-bored/machined/shortblock assembled by Mr Lykins
-racetec custom pistons, scat rods and crank
-bbm heads complete
-comp sft cam
-moroso t pan, hv oil pump,
-edelbrock aluminum water pump
-stock adjustables + endstands, solid spacers, new center stands, crane adjusters
-beehive valve springs+ tool steel retainers
-ati flexplate
-Blue thunder MR 2x4 intake
-2, 600cfm QF carburetors
-brand new duraspark
-BT cast valve covers
-fpa headers, coated
blah blah, I tried to get the best stuff I could for the price, was savvy with spending, and got really lucky when some stuff popped up
Lykins did the shortblock and heads, I assembled and did the rest.
Cost was a hair over $10k
I think if I'd compromised on certain things, there is no reason you couldn't put it all together for $8-9k depending on your spare parts stash
(freakin ATI flexplate is $300+ and I didn't really need an edelbrock water pump, dual quads is cool, but you can do it a lot cheaper).
