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 .
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
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.
I upgraded all my suspension stuff but my springs before im getting my v8 im almost there just need to get some sway bars and v8 springs but after that ill be set. I got 8in rear end power brakes and disk brakes on the front and all new brake lines along with all new bushings and an adjustable proportioning valve
