Stock was:
3.1875" bore
4.00" stroke
6.8:1 compression ratio
112@3800 horsepower
Cubic Inches = 255.352577874595Litres = 4.18453006038044

Going to be:
Bore = 3.3075"
Stroke = 4.00"
Over Bore = .120"
Cubic Inches = 274.941036388258
Litres = 4.50553129784276

Not sure on compression ratio, but I do know the Offy cast aluminium heads were I think 8 or 8.5:1, and they've been surfaced.
Isky 77B cam, Johnson lightened lifters (hollow), ported and relieved, Mallory and a 390CFM Holley on top of an Offy 4bbl intake.

It was fast before at .100" over.....and I ain't gonna be hauling around 2K pounds of tools and equipment.

Should have the block back first of the year.
 
Okay, I'm guessing a Buick/Rover "215" V/8, nicely tweaked.

Am I close? :square:
 
That's called "relieved", and it is. Plus the porting. Plus the cam. Plus the 120 over. Plus the 4bbl, plus the Holley, plus the headers and twice pipes......
 
Whoa!! This for the truck? Ya better get some ground effects stuff on that thing, man!!! :jester:
