Dyno 5.3 Home Ported Heads '84 Chevy C10 LS6 Cam 4L80E Truck
I finally got the truck on the dyno (4 Jan 13) for the "After" dyno. After the home ported 862 heads with 2" LS1 intake valves, .030" mill and a tune on my 155k mile 5.3L engine with LS6 cam through a 4L80E. There are a couple variables of course (always are). For one the weather was the complete opposite as it was the first time. A lot cooler. Around 55 instead of the 100+. Another is that this was with the tune adjustment. We dont know how lean it was on the first run before the heads. Either way, the truck put down respectable numbers with a baby LS6 cam and the 80e trans. It had an increase of 47rwhp and 55 ft lb of torque. Bringing it to 329 rwhp and 334 ft lb of torque. Thats very close if not right at 400 hp at the flywheel accounting for the hp loss through the 80e trans. No longer running lean. Cool part is that this is exactly where I guestimated it to be. Now I just need to hold back this itch for a larger cam and focus on my Turbo LSx 92 Camaro build. I do think that this truck could greatly benefit from a stall on this 80e though. I just have to remember that the purpose of this build is to be a street work truck to tow my Camaro around and not a race truck. ------------------------------------------------- Video Playlist of this project: https://www.youtube.com/playlist?list=PLF96C185A6DFCDE58 ------------------------------------------------- See this truck dyno before the ported heads and tune at Holley LS Fest 2012 here: http://youtu.be/k6YqtLozhyU ------------------------------------------ This truck, '84 Chevy C10 Truck LS Swapped video playlist: https://www.youtube.com/playlist?list...
