good advice from Spyder.

The ports on your '78 heads will be fine. Figure ~$350 for the machine work to tap them for the MFI injectors on top of whatever else yo are doing to them. Your T throttle bodies can also be rebuilt and bored out to 39mm on the intake port side from 41mm. Find a set of '70-'71 mag stacks and take them 41mm-46mm. Camgrinder can add the drive gear to a 4 journal cam. Dont forget the breather cover, linkage bits, airbox, engine tin pieces, injectors, etc that are all MFI specific.

I dont know how much of this stuff you have to start with, but I would figure $5k minimum for parts & rebuild work if you are trying to source everything. Probably not what you wanted to hear, but let me know if you want me to add up the pieces Ive collected so far .

The cheapest way to do this is to wait for a complete big bore system to come up for sale. Ive seen two in the last year for under $5k and passed on them becuase I thought I could build one cheaper.
