how come the 64-66 and the 69-70 engine compartments use the same size monte carlo bar, when the 69-70 can hold a bigger engine and the 64-66 can barely fit a 351?

 

The shock towers do not prutrude as far into the engine bay on the later years providing more room for those massive big blocks.

 

One day.... Im getting a coil over system, and removing those shock towers. Then it's big block time.... or at least 351C time.

 

the 64-66 was ment to have the straight 6 or a 289 first year with a fe in it was what 67 but still was a tight fit you could always do the heidt mustang 2 ifs on it and lose the shock towers heres a link for it http://www.mustangdepot.com/OnLineCa...ion/heidts.htm
