Welcome - this is a great site and I think you'll find us fairly outspoken on everything from cars to "you name it"..

I think you have way too much cam for this application. The 882 head is not going to work. It is a low compression, open chamber head. The 270 degree duration and higher lift is too much for the heads. It will be difficult to drive occasionally, much less a daily driver.

Their web site offers the following description:
“Magnum™ Cam
These cams are very aggressive, designed for performance oriented vehicles where they will see little street use. Stock components are generally incompatible Changes are needed in rear end gear ratios, headers and the torque converter.

270H Magnum™ is a great cam for high performance driving in street machines. The 270H has a rough idle in small blocks and a noticeable idle in big blocks. This is the largest cam you can use with a stock torque converter. The 270H will not affect power accessories, but should be used with headers and a 4 BBL. carburetor. This is the perfect cam for cruising.”

You may be able to use the stock converter - but the 882 heads are your problem.

Just my two cents - others will chime in.

Good Luck,
Glenn
