Hi, First post so be kind..
Ive read a lot of forums and bought all my bits.
Read 2 books Back to back..
Bottom end is built, cam is timed.
And im concerned that my comp ratio is too low..
Ive calculated it at 9.4 to 1..
Im in aussie and regular unleaded is 91 octane.
The galaxie has a 300hp thunderbird special in it, its original, tired and pings like crazy on regular unleaded.
New motor is...
390 block, fully machined,main cap stud girdle.
4.250 rpm steel crank, scat h beam rods, diamond 4.080 pistons.
All balanced.
Edelbrock Keith Craft stage 2 heads 76cc
T&D rocker assy
Pistons are 17cc dished, and sit 0.007 in the hole.
1020 felpro head gaskets
Cam is Lunati Voodoo hydraulic flat tappet 62004
Intake port matched edelbrock perform rpm
ICE dizzy and spark controller
pro systems holley 850 cfm.
My biggest concern has being to match all the bits to get a combo that works.
Cam specs are.

This motor is going into a original 1965 LTD galaxie fast back.
It has A/C and power steer.
Automatic.
Also a diff ratio thats really tall.. Maybe 3.00
And standard wheels and white wall tyres with original hubcaps..lol
Might need a wheel/tyre upgrade..
Is my compression enough??
Is my cam correct??
To get the galaxie to go and match this motor, what size high-stall and diff ratio..
Will i get 500HP and 500ft?? or
