My brothers 69 Barracuda, 360 4 speed, J heads(supposed to be ported), small hydraulic cam, single plane intake, TTI step headers, 3.91 gears, 26" tall drag radials.
Ran a best of 14.70's low 90 mph in the 1/4.
When he had the engine rebuilt the FIRST time I questioned the low cost of it.

Lets just say the issues with machine work and assembly are too numerous to mention.

The car hasn't been to the track with the new engine but the engine dynoed at 411 hp @6000 & 426 tq @4200 if my memory is correct.
