You have a windsor motor, correct?
The vertical height difference of a 351 vs 302 is more or less 1". Obviously differing intakes and whatnot will change anything beyond that.
The windsor is also ~50lbs heavier but can be offset by using Al heads (but you can also get the 302 close to 400lbs with al heads).
There is no way a T5 would be enough, even a world class. TKO would be the minimum you would need.
All of that aside, a 351 will make a TON more power with a great H/C/I combo, and will be extremely torquey. Even more so, if you stroked the 351 to a 408 you have the potential to make some serious power.
You also have a much stronger block, as 302s are very weak with big power in the lifter valley, crank journals walking, etc. 302s are a time bomb around 500hp, whereas the 351w blocks can handle upwards of 750hp (early blocks are especially strong). But the 3" mains hurt if you want to spin past 6500rpm.
Just food for thought.
