David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

Here's 318/360/340 stock bore but same crank


Stock stroke 318 360 340

3.31" crank 318 333 340

3.58" crank 344 360 367

4.00" crank 384 402 410

360 has a 15-18 cid advantage over a 318 with same crank not really that much, no one would think the 340s 7-8 cid would be much advantage over 360.
