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 heads and a tune on my 5.3 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
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.

before the ported heads and tune at Holley LS Fest 2012 here:
