I want to put 1.7 rocker in my hotcam setup so i can increse my lift.....i ran the number and if i did the math correct it shoud raise my current lift of 525 up to a nice 557. I know I will have to get larger valve covers for rocker clearance but what about valve/piston cleance i really don;t want to be crushing any valves. I also have my heads milled .020 so i know that will come into play. I also know i will have to change springs to support the rockers...anything else you guys can think of?? ..will i loose any driveabilty or anything??/

thanks

This is a post on my local F-body board about switching from 1.6 RR with his hotcammed Vette to 1.7RR and gained about 15 RWHP.

Just get a cam with the Hotcams duration ground with more lift...less hassle and much cheaper in the long run...
