Upgrading to 302

Currently running inline6, bought a 302 block and buying a c4 transmission . My question is should i or not upgrade the frontend ,or is the inline suspension which is new ,good enough ? Will the 4 lug rearend stand up to the power of the 302, which when im done the engine will push 400+ hp. Suggestions appreciated Ty .

I'd upgrade but the stock front CAN work, albeit not very well.

UPGRADE. Everything equipped for an i6 isn't meant to handle the weight and power of a v8. Spindles definitely need to be swapped to v8 along with everything suspension wise especially your coil springs since the new weight of the 302 will weigh down on the i6 springs

You need to upgrade brakes before anything.

The suspension components, except the springs are the same. The steering components, including the spindles are the difference. Your rear end will explode almost when you drop it in drive if you try to put 400 hp through it! Seriously though you'll want 5 lug all around. So an 8 will be fine for now. Don't forget exhaust, radiator, and V8 fuel line. Engine wiring harness is different too. Throttle linkage. Drive shaft. Lots of threads in the forum that list everything you'll need to do. Do it right and make it safe.

No upgrade to 5 lug disc brakes all around and buy at least an 8" to hold the power but preferably an 8.8 or 9"
