hawaiiduster!!!
ol buddy!! :)
j/k
what do you want for that manifold? fair price, ill go with it, i wont be slapping it on right away anyhow, i dont have a carb. but i want to secure the parts so i can do it all at once.

i was going to go with the mopar performance orange box for my control unit.. you say an MSD box instead? what about a coil? should i get a more powerful one?
