mopar big block 383 solid lifter 528 lift
 

need some good news on the 528 solid cam, 383 with 9:5 compression,486 rear gear,3700 B-body,915 heads,torker,will it go in the11:50's ,i have the 557 cam in at 106 but,i think it is to big,no low end ,12:40 @106 ,.8" ATI slicks are 9/30-15,stock 525 AFB,Wilson 4 hole sucker,

Get your self a Custom Comp Cams and have them build it one a 108 lobe and make it a tight last, .016 .016 lobe.

No low end with a 489 gear? Think about it. Nope. Probably run about the same time with the .528. The .528 will make a better combo. Not enough compression,not enough head unless they are ported, crappy intake, and you need to lose 500 lbs.Also sounds like you dont have enough converter.

You are talking 4.89 gear and not 489 case correct?

i have run the 528 cam in numerous engines from 383 to 440 and have had very good luck with it producing low end power even with stock 906 and 452 heads. i now have it in a 440 with 9:1 and it does everything i want it to

The problem isn't the cam it is your heads, I have built several 383's but I use either 346 or 452 heads that I port and install lager 2.14 and 1.81 valves. They will flow in the 280 cfm range. I recently did a set for a customer we put on a .030 over 440 in a full body 67 GTX at 3988 lb. that ran 11.60 through the exhaust with 8" drag radials. If you have any questions call 724-791-2514.
Thanks, Bruce

Thanks for all the input,,I installed the 528 cam,at 106,car runs 11:20,not bad for only a cam change.Bigger is not always better.
