Thread: Help a Swede ID his engine!

Tweet

Hi there, Thanks for your answers!

The datecode on the block is "3D10" so 1963 it is just as you said FFR428.

So your half Swede? Well look at that, How did that happen?

So, it´s a plain normal 390" then, Good to get that figured out..

It doesent have the usual "352" in the front, Just "10"
And in the back if the block theres one digit and it says "5"
And on a couple of places around the block, theres the digit "1"

Does this make it different in some way?

The engine was actually rebuild about 2 years ago, But as i intend to put a few goodies on it, It will get another round at the shop, And an overbore to make the CJ valves fit..

This will be added to my engine:

Edelbrock Performer RPM heads and a matching cam for these heads.
Crane "gold" roller rockers.
Holley Streetdominator intake.
Holley 750cfm carb.
Hooker supercomp headers.
Milodon oilpan and oilpickup.
And a 2.5" Or 3" exhaust, right out under the door..


This will be hooked up with a newbuilt C6 with a tuned +3000 Rpm stall converter, high performance bands, Shiftkit etc..

Hopefully the parts will play good together =)

And does anyone know how big overbore i will need to clear the CJ valves in a standard 4.05 block!?

Thanks again!
