Default need your opinions

Id like to get into some competitive autocross or road course racing with my 84 crossfire vette

for performance gains and trying to keep it streetable and maintain somewhat decent gas mileage im trying to decide if i should keep the crossfire injection and do a rebuild with performance heads, cam, underdrives, delete the a/c, headers and full exhaust

or swap over to a lt1 top end rewire the car and do all listed above but a couple other bolt ons t/b, etc

or do the old carbed route with a 800 holly street avenger carb, edelbrock intake heads cam headers exhaust


what would you guys suggest?

im leaning towards lt1 intake swap

Carb? I think you're gonna' need a center-pivot float carb for autocrossin', like the old mustangs, if ya' go with a carb.

If ya' wanna' keep fuel mileage reasonable, go to a TPI intake...
