For my program, I need the exhaust side of flow numbers , , I guess 3" exh is run thru headers, any head cc #? At this point it falls off bad by 5200 and nothing over 500, hp or tq.. need more info

It has an Isky 396255 cam, I tried to paste a link but I am tech-helpless. 119cc heads, I don't have the flow bench numbers for the exhaust but I will contact the seller, thanks again

Well those numbers are important but basically I see the motor has a bunch of tq up to about 4500 then goes down. I plugged some BBC exhaust numbers in and its not too much better, cant find any mention of a Vortec head for BBc. I found he cam so those numbers are in . Basically I find @ 3500 , 400hpx 600tq, 4000, 447hp x 587, 5000, 490hp x 515 , 5500 goes down quick. Like I said, air flow is generic on exhaust, cam is right, head cc is not in line.
