347 vs. 351 in 69 Mustang

From a cost standpoint stroking his 302 (to whatever size) with some good heads and a solid flat tappet cam he could meet his goal without going too radical.I wouldn't waste anytime with factory iron heads.

A good running 351 is nice as well.Just depends on the cost.

Yes, that is what we are trying to determine. Trying to judge the retrofit cost to go 351, vs stroker cost of 347. With the 351 comes the added weight, and off course added size within engine compartment for headers and plug changes. We are trying to find the balance between the pros and cons of either setup.
