Building a rat rod and I'm using a Honda Passport/Isuzu Rodeo chassis. Cab and front end is 41 GMC. My motor is a 75 455 with T400 transmission. I am thinking that I need to get a set of universal motor mounts and weld them in and I have gotten advice from a guy who's used this frame for several 350 swaps. He thinks there will be no problem but I like to get more info before I start up the welder.

Is there a Buick mount that seems better or will the universals likely do the trick? Any input is valuable.
