The Chevy II gets a new front suspension and 454
In my opinion the Chevy II is better suited for a small block, front to rear weight distribution, fit and cost. But got a big block given to me and never had a big block and always wanted one, so here I go... 
I went with a Heidts weld in cross member and will use Mustang II components
This page is a start. More to come later.

A last look at my trusty 350

Ok, Another last look. 2nd thoughts now about doing this.
Before starting I put car on jack stands, leveled very corner and measured everything everyway i could imagine. Measured front frame rail height before engine removed, after engine removed and checked after every modification

The front end gets cut off

The left overs


The frame rails get notched out and a "C" section gets welded in to allow for spring clearance

The front cross member gets welded in. All the while constantly measuring to make sure the frame rails don't bend up or down or in or out from the heat.

Added extra gussets on motor mount brackets to handle extra toque from the big block

The engine gets dry fitted. I slip on the radiator support to make for sure front of frame rails didn't move in or out.

Cluth link info

Checking oil pan to steering rack clearance before welding in motor mount brackets. Put front as low as possible for throttle linkage clearance. I think an HEI would fit w/o mods.

The fire wall plates. I had cut out from an 1/8" and 1/'16" plate and stack together

Used 2" schedule 40 pipe. Took it down to the muffler shop and had 70 degree bends made on them.

Making sure the support tubes have plenty of header clearance

Fitting and adjusting the support tubes prior to welding
