[BRENT in 10-uh-C]

Based on my experiences installing several 3.27 ratios, it is not the head that makes or breaks the deal. It is the cam. I have installed one 3.27 ratio with a stock head (milled only to true it up) and an IB330 cam and it did fine in a '30 Coupe albeit not as agile as one with better breathing and more compression. I have also installed a 3.27 in a '29 Roadster that had a rebuilt engine with a Brumfield head and a 'touring' cam. It was a 'slug' IMHO.

Those two cars and their drive train were not totally comparing apples-to-apples, but it has allowed me to form an opinion that camshafts create better driveabilty than what a hi-compression head does. Note I did not say more horsepower, just better driveability.
