Hey guys - my 383 LT1 is almost done but I'd like some opinions / input.

1. If I replace my throttle body to a 58mm unit, am I going to have to swap my sending units from the stock TB into it? It seems to me that most aftermarket throttle bodies do NOT come with any sensors.

2. With a ~450hp 383 i know I'm going to need bigger injectors. But what's a reliable manufacturer to go with? And what size? I was looking at 30 lb/hr injectors from Accel on ebay but I'm not sure...

3. I've upgraded to a 1995 opti spark - but I have *for now* a 1994 harness. Do I need to buy the opti spark harness to make the setup work?

4. I'm planning on running A/C delete, AIR delete, EGR delete - so I'm thinking my computer will need a fair rework - any recommended sources to try?

Thanks a lot guys!!

1. Yes they dont come with sensors.

2. www.racetronix.com

3. Yes it wont work with the connector on the earlier harness.

 

If you go with the 58mm tb you will have to open up your intake to 58mm.

 

Thanks for the tips so far gents! I'm waiting for my opti spark and timing cover to come in, then the top end goes together. I've ordered fuel-rail adapters (quick connect to 6 an) and I'm going to pick up my TB and injectors soon.

Then once I get some money saved back up I gotta find me a T-56 :-)
