LT1 throttle body

[Fedaykin]

There's some cheap ones on ebay right now, I was thinking about getting one for my iron head. but have a concern.

what all do you need to run it on the iron head motor? i'm thinking you probably need the LT1 TPS, maybe another sensor?

Sensors are the same I think. Thats a lot of air. I was thinking about the same for a DOHC motor. Curtis runs one on his turbo setup but for NA dual 48s might be a bit much. Would be interesting to know how it works for part throttle really.

I have a 2.8 with dual 52 mm throttle bodies. Part throttle is just fine. Driveability is the same as stock. 48 twins from an lt1 will be just fine.

i'd look into just a big t/b like the 4.3 vortec t/b
