low 408w rwhp dyno number..please look and help
I ran my car today and managed 326hp and 350 tq at the wheel through a AOD with 3600 converter. I know the converter and AOD are eating some HP but I was exspecting more.
408W all forged balanced and blueprinted 10.5 to one
twisted wedge 11r heads 190cc
holley terminator efi
stealth intake
cobra style air cleaner
1 5/8 headers
link bar lifters
roller cam 218/226 571/566 with 110 separation at .50
march serpentine set up
2.5 exhaust with dynomax mufflers
I would think this combo would be closer to 375 and 400 tq.
thanks

Those #'s do seem way low. Was this after tuning the Holley EFI ? Or was this the just a baseline pull ?
Or the converter is skewing the numbers. Any chance of a couple 1/4 mile passes in the future ? That will tell the truth.....

you need to log more info on the dyno, air temp, air/fuel ratio, timing, etc. any of these will effect power, not to mention did the fuel injection learn all it needs, it may take a while for it to dial itself in all the way

I am with the rest of the guys take it to the track. But I will say this I think the intake is wrong. put a victor jr on it. and the headers are to small for a 408. That thing needs lots of air. IMO

Kinda seems to me youve got a big motor but the heads, intake, and headers are holding it back. Ive got the same heads with a trickflow intake and 1-5/8" LT headers on a 331 and I made 350 hp on a mustang dyno with the timing incorrect. Running a holley dominator efi on mine.
Sounds like you need to do some more tuning on it but those hard parts might limit you some.
