So you want 2 go Big block...Read this first!

Probably realistic, but my first big block swap (440, 18-spline four speed, console, Hurst shifter, Barracuda dash with 150mph and tach, 15" rallye wheels, 3.23SG 8-3/4 with 11x3 rear drums, big bolt discs, factory big block t-bars and sway bar - I'm probably forgetting some subtleties and small parts).

The total, including the FREE 67 Dart GT body (rust free, too) was around $2,600. I got some SMOKIN' deals, though. $150 for a low mile ORIGINAL 1970 440. $135 total in the 18-spline four speed.

I'm in the middle of the same swap on my 67 Barracuda convertible. Here's the prices:
1969 440 - free (well I stored the truck for a year and a half for free, too)
727 - kit and convertor will cost around $100. I've had the trans for a long time and it was basically free.
3.23SG 8-3/4 - $100 for the housing, $50 for the brakes, third member came out of a car I parted.
Big bolt discs - came with the car, installed.
Big block sway bar (yes, we have two factory bars) - $40
150mph speedo/tach - $25
15x6.5 steelies/tires - wheels came from the same parted car as the third member, current set of tires were on my son's Daytona
K-member and mounts - $40 if you include the welding wire (this may go up a little if I buy new inserts for the spool mounts)
Exhaust manifolds - kind of hard to figure a price because I have bought so many, but figure $75 for the pair.
So, I'm at $430 and I don't have my cam yet ($210), driveshaft done ($70), exhaust system (I've got some parts, but figure another $150), and torsion bars ($200).

$1060 (give or take a little) and it will be running/driving. I will also be painting the car and doing the interior and top. I should be done and cruise-ready for around $3000 on top of what I paid for the car (Jim, thanks for the good deal).

If things go well this year I should have it ready to cruise by next spring.
