can get my hands on a reman. 454 (stock is all i want for now) and would like to put it into my 1/2 ton burb. Though i have a few questions.... going into 1988 4x4 1/2 ton 350 tbi bone stock as of now 1.i know that i will need custom exhaust... i am ok with this.. will probably use headers that were meant for a 3/4, they should fit right???? 2. Tranny, i have the 700R4 and do not want a th400, can i keep this tranny, and if so what modifications need to be made. 3. Motor mounts ?? simple question, but probable a stupid one, 2500 454 mounts??? 4. Fuel system and computer... do i just find a new ecm to go with the big block or will mine do with a new chip.. im sure i can find a tbi intake and tbi unit.. what else will i need 5. Accesories.. i want to keep ALL of my accesories. This vehicle has working air and i would like to keep it... will my existing accessories blot up to new mounts... i mean are they the same parts, just with different mounts that i can get from the ol' yard... i want everything to work as stock 6. the truck will be getting a 4" tuff country kit with the ez ride springs... i know this 454 weighs alot more than the 350 so what does a guy do... , can i use a front 3/4 leaf??? add a leaf into the tuff country???? thx for the help... and if you all have anything else to add i would appreciate it.
