of course i fondled the manifold and they had it sitting right next to a hi ram, but i did not take any pictures.

i believe they are $1299. i think the price is 100% reasonable for what the manifold offers.

runner length options:

6.5, 8 & 9 inches
165, 203.2, & 228.6 millimeters

comparison:

LT1 155-225 mm (unequal length)
LT2 210 mm
msd 198 mm
hi ram 165 mm

only power comparison ive read about was on a stock c8. supposably gained 25+ whp with a LT5 tb on an otherwise stock car. naturally, i'm skeptical.

How much more HP and Tq on a stock LT1 SS?
