Replacing the stock 882 iron heads with 200cc RHS aluminum heads, an XE274H hydraulic flat-tappet cam and Pro Comp dual-plane, aluminum intake resulted in some serious power. Fed by a Holley 750 HP series carb (we should have tried a test with the stock Q-Jet-sorry), the upgraded L82 produced 414 hp at a slightly higher 5,900 rpm and 415 lb-ft of torque at 4,100 rpm. The upgrades to the L82 improved power throughout the rev range, from 3,000 rpm all the way to 6,500. The gains would be even greater on a milder small-block (from, say a truck) since the stock cam timing would be even milder than the L46 cam used in the L82. « | 1 | 2 | View Full Article By Richard Holdener Enjoyed this Post?
