Just posting my new dyno chart after the installation of JLP long block.  Dyno results were 586/650.  Latest work entailed:
JLP Built Motor
CNC Ported Heads
Stage 3 Cams
8# Lower Pulley
MAF X Tender
JLP Afco  Heat Exchanger
KB BOOST-A-PUMP
PI 2800 Converter
JLP Polished Valve Covers
Gauge Pod
Autometer Boost Guage
Autometer Fuel Pressure Guage


Decided to get a motor after reading of all the head and rod problems.  I March I had a KB installed as was at 450rwhp.

I'm satisfied with the numbers and the truck is running great!  Have 300 miles on the new motor.  Looking at the weather it will be sitting for a while.  But, I'm ready for spring.

Any feedback? What should I do next?

Very nice numbers.

Would you happen to know what the numbers were in SAE?

I have a pretty good guess based off you STD numbers.
Just curious how my combination will compare to yours.

How much boost are you seeing?
Did that dyno include the sheetmetal plenum?
Seems like you have everything you need.

For a race setup, I would add a 10 lb lower pulley
and maybe a 2.8 upper pulley, some 60 lb injectors and spin that KB to make some boost.

Add a racetested 100 shot of nitrous... and HOT DAMN if you won't be moving!
I think of making the above changes far too often than my better half or wallet likes.

If you don't have one already, I'd suggest a dynojet wideband commander.
Add a map sensor and you'll be able to monitor tps, A/F and boost throughout the rpm range

I am seeing 15# of boost and the dyno was done with the sheet metal plenum. I have a 3.5 upper pulley on it now and have another 3.0 pulley. JL recommended I break it in with the current configuration and then think about making further changes to increase the boost. I think he said I could go as high as 20# of boost. It sure does haul a$$ now though.

I am also thinking about getting the wide band commander.
