I have a 1991 Trooper 2.8l V6 LS I have put a hi-flow 2.5ö exhaust, a throttle body spacer, and put injectors in from a 4.3. Currently the engine is being rebuilt. Overview: three angle grind, bored out pistons, slight upgrade cam shaft w/ adjustable Edelbrock sprocket, roller (tip) rockers, bored out a few other things. IÆm also putting in a new clutch for good measure. Any suggestions about this, has anyone had luck re-mapping the ignition with a jet chip?

Question1:
Headers: I found a likely fit on Edelbrock's website part #'s 68972 & 68973 are for the same 2.8, but for s-10/s-15's, I wonder . . .

Question2:
K&N and airRaid do not make air intakes for this engine. Other than a custom job, anyone have any ideas on getting a cone filter in there? There is not much room after the throttle body spacer.

I welcome any suggestion or comments.
