I'm building a dart block 331 with afr 185's and 30 lbs. Have two to three weeks to finish getting the final parts together. Could anyone give me advice on what long tube headers i should run?? Was told the bbk's are easy to install but not sure about it flowing the same as other brands. Anyone know any facts about different long tube header brands?? Also will need a clutch not sure on that one either.. thanks for any advice given.
