TBI swap

[Violentv8toy]

I want to go TBI. What all is needed to do a TBI swap? What do i need? How good is pro-jection? Tell me what i should do.

projection sucks

for a small block GM you really should do a factory style setup instead of an aftermarket kit.

you'll need the harness, intake manifold, computer, throttle body, and distributor along with all the sensors. You'll probably have to wittle away at the center 4 bolts for the intake to get it to fit an older block.

most of the gm stuff is the same between cars, and most junkyards always seems to have a "$2 for all the sensors you can fit in your pants" special going on. Just make sure you get a memcal (small chip) from a 350, and the eprom for a 350, and the injectors too. thats about all that is engine specific.

The ECM you need is from a v8 truck, or a v6 astro van and the last 3 digits are 747.


Theres not much to it, if you have specific questions shoot. www.diy-efi.org has some schematics in the gm_ecm section.

[aggiemudman]

i too am thinkin of going tbi over the summer since i got the painless gc from tcc. as far as upgrading to a better throttle body would a 454 one be better than the aftermarket holley one? anybody got any ideas for an inline fuel pump?
