would a new set of mounts for a 350 in a '35 ford (currently 283) be a direct swap from the current mounts or no? would we have to drill or weld the new ones on? sorry...kinda dumb question i know...i'm just trying to get through the most critical steps in the swap to be able to keep the engine running and we dont have a welder so im trying to guage how far we can get with this right away...thanks!
