Well, my point is I don't think everyone expects an honest 425hp out of the LT4 conversion.Transamman25 said:See thats Crazy ! evryone knows the LT4 conversion is suppose to step the HP to 425 .. which i felt but when we dyno'd her she put 327.2 HP and 341 ft lbs of tq. .. which was explained to me as a 20 % driveline loss .. "shirley there must be something can be done" ..
Swing by www.speeddensity.org seeing as you've got a 93, and have a chat with PCMFORLESS. He can probably wrangle you a good bit more HP out of a tune.ihaterice said:255hp and 298 ftlbs were my final numbers comming from a baseline of 233 and 276
