That sounds incredible! Those non supercharged cobras are pretty amazing. If memory serves, I saw someone put down 420whp in one of those with just a tec3, ported intake manifold, Griggs Racing headers, X Pipe, and hooker mufflers. It was running some kind of race gas too but I was still really impressed.
he said factory headers

stock they should put down 260 whp so with headers, h pipe and mufflers 280 whp is awesome

ok i know this was a year ago but 305 is crank hp - about 12% is still 269, usually you don't see more than 13% loss through a manual drivetrain.

@shonzy7
that 260whp isn't really accurate(for a stock number) and he probably only picked up 9-11whp from those mods.

the numbers were 278rwhp and 262rwtq if I remember right. It was on a Dynojet.
