shift kit no, converter will effect #s ... simply locked or unlocked, but also as you get into the STR of each converter and how much slip it will allow unlocked, depending on application may only be 2-300 at redline some may be 2 or 3 times as much

locking up a converter under wide open throttle is ******* the torque converter and the transmission but will yield the highest numbers as the entire driveline will be connected much like a manual transmission.

I have a stage 2 Texas speed high lift cam , dod delete , ls6 springs , ls7 lifters , ls2 timing chain and sprockets . While getting the cam replaced , my mechanics noticed my cam bearings were worn so had the whole motor pulled , all new bearings , pistons and rings and balanced . Made 271 hp and 284 lb/ft . The pull was made with stock 20” rims and in 4th gear on a mustang dyno

Ohh man that doesn't make me feel good about my up coming build. I was really hoping to break 300whp. The only 2 things i have different that can help hp is ill have upgraded trunions and PRC CNC ported 243 heads.

The guy said I would get another 30-40hp on a standard drum dyno . Said his mustang dyno was stingy

Heres a walk around before tune..

Eric, did you notice the cam bearings were worn, befor ethe delete install or after? I just purchased one from TSP, along with LT headers and a torque ocnverter

I just had mine dyno'd monday.. Due to adding the Edelbrock E Force supercharger
to my 6.2 denali -+ 2014
I put on Kooks Headers and Y pipe with cats too...
I only got 352 hp & 380 Tq.. By the speed #'s looks like they did 3rd gear
I'm going to take it back for a "touch up" next month with better fuel, so maybe
that will change.. But I'm kinda disappointed with the #'s so far...
Just got the front fascia, wheel wells, etc etc all put back together today so haven't
really driven it yet.
I talked to Edelbrock, they said they would normally see 450 HP from the 6.2
with their charger.. Mine was on a stingy mustang dyno so I'd figured around
400 hp...

I would've thought at least 400 also. I wonder if they got everything out of the tune that they could've.

350 at the wheels seems on the low end, but many factors as mentioned to consider, especially when you consider the fuel.

Just an example, i playing at the 600 mark at the wheels on an AWD dyno, 6.2, 6L80, headers and cam on 93 octane w a TVS2300.

Just curious, do AWD dynos actually measure at both rear and front rollers, or does one set just free roll?
