5.0 Throttle Body upgrade

Looking for info on Throttle Body upgrade options.

1990 LX 5.0 HO
Installed now:
BBK Cold Air intake
BBK Shory Headers
BBK H Pipe
Flow Master 5 series mufflers
Flex A Lite electric fan
MSD 6ALN ignition Box
Stock injectors
Stock Fuel pump
Stock Fuel rails
Stock CPU


Looking to push the HP a bit without a big disasembly of the intake.

I have heard horror stories of adding a larger Thottle body and screwing up performance with out adding other parts.

Just want to poll the list for the best idea on how to proceed.

Check out the latest issue of Hot Rod. They have a great story on an efi junkyard build. Should help you out.

Thank you.

I'll check it out

Looking at your mods a bigger throttle body won't help you much in my opinion.
