sorry if its a stupid question, but if i get afr 227 heads ported and polished with a custom cam, what would happen if i didnt change the torque convertor to a higher stall and leave it stock for like maybe 4-5 months then get a m6 with mcloyd twin disk clutch?
thanks

 

The worste I heard is the car wants to roll forward while the brakes are completely pushed down.

 

^^That could be pretty bad if you plan to drive it on the streets.
