Ok heres the deal. According to the desktop dyno this motor makes 389 hp and just over 450 lb/ft. The best part is it is building 400+ lb/ft from 1,300rpm all the way to over 6,000 rpm. Heres what it has Its a 383 with 5.565" rods TRW forged l2256f.030 pistons aftermarket 400 crank built for a 383 (I think it was a PAW crank thats where I got it) Clevite 77 bearings Chrome moly rings ARP Chrome moly fasteners High performance Vortec heads part number SD8060AKIT http://www.sdpc2000.com/cart.asp?action=catalog_start&catid=2172 This is an upgraded Vortec head kit Edelbroc Performer intake that came with above kit Comp cams Xtreme 4x4 cam 12-235-2 210/218 @ .050 440/462 lift 111 lobe separation Quadrajet that has been modified to flow 950+ cfm and rebuilt with a carbs unlimited Master strip kit with 70-77 Jets three extra sets of secondary metering rods (I will also throw in an extra q-jet and all jet and metering rods I have left) Millodon high flow oil pump Millodon circle track oil pan with windage tray Stock distributor with advance kit This motor was built with all new part and is all ballaced. I only have about about 2,000 miles on it. This combination yeilds 10.783:1 compresion way too much for a daily driver. When I ordered the kit I told them I wanted to shoot for 10:1 compresion and they told me those were the pistons I wanted. I have since done the math myself and found out they were wrong. (the above hp and torque ratings were figured at the 10:1 not 10.783 so those figure should actually be higher) The bottom line is my truck has a drinking problem (try 7 mpg) and only likes the expensive stuff. So heres my proposition I want a late model vortec motor with EFI and computer. I will trade straight up or take $4,000 for it. OK the Desktop Dyno #'s I used were from memory of my brother doing it on his computer so I went to Kazaa and found Dyno 2000 and this it what it sais RPM HP LB/FT VE 2000 164 431 80.5 2500 209 439 82.6 3000 253 443 84.3 3500 298 447 87.1 4000 335 440 88.8 4500 363 423 88.6 5000 368 386 85.9 5500 352 336 81.4 6000 318 278 75.3 Thats quite a bit less HP than Desktop Dyno said but I can back these #'s up.
