Ok well I have the 1964.5 mustang project car that was posted here. I plan on putting a 351w in it and not factory but dont plan on going crazy. Someone told me I should full frame the car and subframe connectors wouldnt be enough. Dont know how much power it will be or anything I never built a 351w so maybe you guys can shine some light on that for me too. Also would anyone think it would need a cage will be a auto car good converter unknown size of stall. I know there is alot of variables to go threw but just wondering. thanks
