i still disagree and stand by what i said earlier. shaggy's car has better heads and more mods than mine but ive done my homework and an open spacer on a dual plane does nothing but hurt performance. its a cheap mod though so go ahead, i love to learn things on my own too. an "upgrade" to a c-6 isnt necessary when ive seen c-4's run behind big block cars with more power than most wild small blocks. why add the weight? i would also stay with 2.5" exaust at the largest. ive seen too many guys put 3" pipes on their car only to run slower because they killed the flow velocity of the headers not allowing them to scavenge the cylinders. the whole engine is a system, if something doesnt match the combination, you'll never see its power potential. also i woulnt overcarb a smallblock with 700 cfm, especially not manual secondaries with an automatic. oh well. it just like they say.....ask a question, get a conflicting answer between every gearhead.
