upgrade questions
Hello enthusiasts,
I am pulling my '86 3.2 next weekend to upgrade the cams. I am undecided on what style cam to go with. My car is strictly a street car and I do not want to change the stock look. Can anyone tell me the bhp benefits of a few different streetable camshafts? I will put a SW chip in the car with a bypass pipe after the cam switch has been made. thanks much! John

Let me make this a bit easier for those in the know. These are the cams I am thinking about going with. Can anyone tell me the bhp figures and the pros and cons of the these?

John,
I have 964 cams in my 3.2L. Great mid and top end. I hope to have HP numbers in the next couple of days...

I've got the 964 grind cams also. I recently dyno'd the car and the results were 258 hp rear wheels assuming 15% loss SAE corrected at 248 hp. This is with a couple of other modifications so I have no idea what the gain was with just the cams. I am very happy with them and need one more upgrade to a SW chip to get the best out of the changes. Plus the sound at idle is really cool.

ACH! That was crank hp not rear wheel. Rear wheel was 218 SAE corrected to 210. Sorry about that guys. I wish I was getting 250 hp rear wheels!
