[montecarloss90]

i am hopefully planing on to swap engines from the stock 4.3 to a 87 350c.i calibrated. I would like to know that the transmission can hook up to the older engine and how will i need to wire it to make it run? also for the trans line will the fittings fit a bigger radiator or will i need to mod them? also will i need shorty headers or can i use full length headers. also what will i have to do for fuel lines? will the stock ones hook up or will need to be replaced. any info will help.

wish i could help... i didnt think that a 350 would fit !! but i would imagine that everything would need to be upgraded.. the rad.. the fuel lines... i would bet that the fuel pump would need as well... and if you got a set of shorty's use them
