Big block in a 66 mustang?

I have a dilema, my shock tower is broken (control arm "ripped" out) so since I have to repair it anyway, I was thinking about adjusting the shock towers to accomidate a big block. What would I have to do to make a big block fit? Is there anything else that needs to be modified?

Re: Big block in a 66 mustang?

If youve got the money, id buy a conversion kit to make it a mustang II style IFS suspension in the front, which would completely eliminate the shock towers leaving plenty of room for a big block. There are tons of companies that make them, not sure which is the best, but i would check out Year One.com.

Re: Big block in a 66 mustang?

I saw a 66 mustang running a 427 FE motor down at the dragstrip years ago..He had swapped in the shock towers from a 67-70 style mustang and it looked totally factory installed..I am not sure how the 66 engine compartment compares length wise but I wouldn't be surprised if its a little shorter..

I can vouch that the 65/66 frame rails and top of aprons at the radiator support are the same distance apart as the 67-68's.

I was looking at ifs systems and it was unclear if it came with the coil over suspension or it costs extra...does anyone know?

Re: Big block in a 66 mustang?

some come with coilovers some dont. usually an upgrade in cost if it does. i used the RRS strut conversion that chopped the H*** out of the shock tower since it removes the upper control arm completely. This is on a 68 but it may work for earlier models too. Just another option
