I M3 was stock, I know, cause it was mine.I still don´t know what number the 327 is putting out, but I´d say at least around 330-340 HP. I won by about three car lenghts in a 1/4 mile, maybe a 1/2 mile since we did it on the open road. I didn´t have on the dyno but I dragraced a friend in an OT E46 M3 with 343 HP. 040 over with L2166nf dome pistons,steel crank GM cast Camel humps withjust a little clean up, 234°/244° cam, off the shelf Performer RPM intake and 600cfm Carb. Feel free to school me while I continue to do more research. The point of the car is to be reliable / streetable and somewhat fast hotrod. Im sure there are better cams out there but again I could be wrong. Question is where to go from here? Id like to run and Isky cam just cause. Im not apposed to running a manual trans but Im trying to stay as budget conscious as possible, so using what I have would be rad but Im open to suggestions(hence the post). After doing some research on the block numbers: 3892657 (1967 Camaro) and the heads are 3973487 (1971 Corvette) The motor also came with a Man-a-Fre intake manifold and Rochester 2G carbs(4) I also have a turbo 350 trans and a 1957 Olds rear end. When I picked up my '30 coupe(local hotrod built in the 50s and hasn't been touched since '66) it came with a 327 from the 3rd owner who didnt use it. I'm not sure if my aspirations are unrealistic and pardon me for not having a ton of engine knowledge but this is what Ive got to work with.
