302 heads for 318

If you look around and have a little patience you can do really well in the parts department.
I also have a 318/904
It took me almost a year, but this is what I got and what I paid.

Edelbrock 2176? dual plane in near perfect condition = 60
Edelbrock 1406 600cfm electric choke like new = 40
Edelbrock spacer/insulator = 20
Chrome air cleaner = 10
Fabricated alum valve covers = 60
1 5/8 Hedman aluminized headers = 210
Double roller set = 40
MP purple cam and lifters (new) = 100
HEI ignition = 25
Yellow 8mm Accel wires = 45
2.5 aliminized dual exhaust with X = (with flowmasters) = 250

Mine is set up all about fuel economy since I daily drive it all over the county, and is getting an Innovate wideband A/F kit for down to the knat's *** tuning.

The plan is to run what I have right now except for the cam and timing set, and pick up a 360.
I'll have the 360 heads milled and put them on the 318 while I do the bottom end of the 360 over time.

Once the 360 bottom end is done and has the cam and timing set, then the 360 short block will go in with all the stuff that is already on the 318 now.
One weekend and there ya go.
