70gtq

[Dr.drivability]

What do you guys think a 70gtqbb would do to my current combo? Love the way my car runs now but in a situation where I can sell my 67bb and not loose much. Would it be as fast on the street/strip as it is now?

Id go bigger than the 70GTQ if you plan on jumping to the GTQ. Go for as much wheel as possible and turn it up. You should have some high 130 mph runs in there even with the unported GN1's. Ported GN1's would help a little with the 3 bolt but not like if it was a tangential 4 bolt. It may be worth going to a 4 bolt setup to reduce back pressure and have the potential go up a lot more than with the 3 bolt. I wouldnt doubt you may be able to get the same performance with the 67 4 bolted and the appropriate exhaust a/r as the 70GTQ and the 3 bolt.
