Vortec Head swap on my '92 TBI 350. Tuning questions.

[jdyates]

I've tuned several Vortec heads with TBI conversions.

I like the TBI adapter plate pictured below!!!

The AE and PE needed for the Vortec heads is HUGE!!!

The factory Vortec timing tables are a good place to start.

15 lb TBI pressure regulator is a good idea.

Injector flow of about 70 lbs is about ideal!

Data logging is only way to know if the chip is working correctly.

I like that adapter plate as well! Got a link to where I could get one? And as far as the bigger injectors go, i was planning on doing a 65lb/hr police car injector setup with a 454 throttle body later down the road, what do you think?

Some of the truck motors had rollers from day one.

This one didn't. My uncle had it converted for some reason.
