welcome to the garage DAZ, there's a couple members here that have Mapleleaf info, but I think you'll find that the 1700 Mapleleaf trucks had GMC engines originally even tho they were Chev badged [maybe the 228] - and you'd attract the right guys if you edit your post to include the 'Mapleleaf' part, one of them will be along soon
