No....I havn't done it yet.........found more power outta the stock block N/A......Should be closing on 275 rwhp and 310 rwtq with stock heads, cams and block on the Auto! Hard to believe the car only dynoed 212 rwhp stock! Dynoed 268 and 304 the other day @ 81 deg. Putting on a canton windage tray, port matching the header openings and gaskets, and gonna hone out the plenum a little more! If this car was a 5 speed.....290 rwhp could be achieveable. They highest stock heads, cams, block GT I have ever seen dyno was 283 and 314! That was out of a 5 speed. All the little mods and tweeks make the difference though! Car ran 12.97 @ 103.4 the other day with both front brakes draging bad. Should be around 12.70@ 106 with the new calipers! Going to put on some new ported heads and VT stage II's in the near future.......I think high 11's can be accomplished with DR's and 320 rwhp! Want to keep trying the N/A route for a while! Car is almost paid off too! "ED"
