Nothing to check out. An intake built for a 302, will not swap out to a 351W. It physically isn't possible. While the upper may be interchangeable between the two, the lower intake on a 351W is approx 1-1/2" wider by comparison.I got a trick flow track heat upper and lower says it compatible. I was afraid it wouldn't be a straight swap I'll check it out. However apparently the 302 xxx is a dss level 20 block only.

The 351w....but price out swap headers and front brackets ie alternator, power steering, ac, etc...
The lower intake from 302 won't work. The accessory brackets won't bolt up. Headers need to be ordered. Balance is different than a 302. Oil pan needs to change. Harmonic balancers don't swap...and neither do you the flywheels or flex plates. Someone sells a swap kit....I've seen it online but don't know who sells it.
The reward is a block that is at least 49ci bigger and can confidently handle 750hp.
Learn something new every day [emoji106]The SN95 accessory brackets will bolt straight to a 351 block but will require a longer belt.
Actually I forgot to check to see if any shops around can handle that. Thanks for the reminder!I know you already know, but just in case. Have the block magna fluxed for cracks. Small cracks that are not visible to naked eye show up.
