[QUOTE="old01cobra, post: 15545567, member: 141196"] Block is a Boss stroked with dss flat tops, Fox Lake worked 03 heads with stock valves, 90mm maf with 60lb injectors, Fr500 intake top plated for a 96-98 with a return fuel setup and I cut the twin 57mm split out to fit a wide oval SVO tb from a 2000 cobra R with the intake flaps removed and made a fiber wrap 4 1/4 inlet tube running too the wheel well with some custom Bullet cams which were degreed. It put just under 460rwhp and 390 rwtq down. I do spin it too about 7500 rpm and I think I'm at about the limit of the cams I had ground, my calculations may have been off a taste because I wanted 475-500 rwhp but it is what it is now. With a stock twin 57mm tb and the flaps installed with a factory 98 style inlet tube it made 433 and 376 and fell flat at 6500 till 6800 rpm. When I opened the intake It really let the thing breath with the revised top plate and the bigger inlet tube with the SVO tb plus it gave me another 1000rpm. I only spun the thing too about 7500 because at around 7200-300 it stayed flat till about 7500 so I either need bigger cams or I need too hog out the runners of the FR500. So it is what it is but yeah I think its healthy for a NA Modular it should surprise some LS guys. How do you like the 4.30 gears? I just got a set that I will be doing shortly was going to go 4.56's but stepped back a little. [/QUOTE]
