I went with all a 387-388ci all-bore. Whoever said it makes less low end torque than a stroker I think that is an old, incorrect notion now. I was hitting 400rwtq at 3200rpm, peaking at over 450. Best numbers were 459rwhp/453rwtq...This from a H/c cam car that made only 400rwhp, the heads were reworked, but look to still be holding me back, so they will probably be replaced next.
