No, you need to flatten the forward sloping panel at the bottom of the firewall plus you should really get the oil filter adapter that moves the filter alongside the block. t also helps to get the pre '57 rear sump oilpan and the pre '57 rams horn exhaust manifolds.
If you are not running fenders, you can move the front crossmember forward, which also moves the radiator and grill shell forward, to make more space. Lengthens the wheelbase also. The model A in my Avatar sports a 392, in a 32 ch***is, with front x member moved 3 inches forward. So I could avoid cutting the firewall. Also planning to use a remote oil filter, but a forward facing would also likely work. Good luck Sent from my iPhone using H.A.M.B.
