Wow, nice transplant. Are the V6-v8 transmissons the same? just curious about strength.

Id guess around 360-380, with the TC causing some loss. (Of course, it will be much quicker with it though)

Yea, 360-380 is a fair guesstimate with those mods.

yea i had a v6 at one time, they both have 4L60-E for autos, but if its a stick, v6s have a M5 and v8s have a M6


i just remembered you said you were putting in a stall, so the trans should be able to be carried over

I think you will need an upgraded speedo or do they get the same ones?

v6 speedos only go up to 125, but as long as you get it cailbrated you can use the old speedo, but deffinally get the speedo caibrated, the electronic controlled trans shifts based on rpm and mph so if the speedo is off you could ruin that trans

you might want to check out granatelli's 200mph speedo since you would easily be able to bury that 125 mph speedo...it might get annoying if you race to those speeds or not...
