Wanted to see if anyone else on this forum dabbles in this area also.
As someone else mentioned above the pulley mod is very cost effective. The 3800 has an Eaton M90 blower on it. The same thing that is on my '89 Thunderbird Super Coupe. I can't speak for the GM 3800 but with the T bird 5% is okay without any other mods. The 10% however requires a more freely flowing exhaust or you will blow a head gasket. :O
Have fun.
Yeah, thats why I had 3.4 in mind. Is that 5%?
