383 stroker swap TBI/Injector question
I've got a 92 RS 305. Thinking about doing a 383 stroker swap. I'm looking to use the stock TBI unit, however I wasn't sure what or if I needed to replace the stock injectors for higher lb/hr ones? Also are there any recommendations as to in intake for this also?

Re: 383 stroker swap TBI/Injector question
The stock TBI unit and injectors barely flow enough to handle a stock 305 or 350. A 383 is way too much, a TBI cannot support the airflow or fuel requirements. You need to upgrade to a multi-port fuel injection setup to support a 383.
They make 4-injector pods for a TBI, which is better.
