Everything from the 307 will fit and work with the 403 correct?

Timing cover, oil pan, PS AC brackets, engine mounts?

Thanks

Make dam sure you upgrade to a 2 core with 1" tubes or larger aluminum radiator and either a 7 blade fan with a new clutch or good electric fans. Also hardened Yukon spider gears may necessary due to all the wheel spin🙂.

Nope she is just a cruiser, The 307 runs and drives great,

I can cruise on the highway at 60-70-80 and she purrrs like a kitten.

But she needs a little more get up and go.

I gotta get up to 60-70-80 quicker!!!

I have the Malibu for a go fast car.
