i have a stock tpi 305 in a 88 IROC, i want to put in a comp cams LT1 cam rated @ 212-218* @.050" lift with 488-495 inch lift on the intake & exhaust. i'm planning on using the world s/r torquer 305s with the cam upgrade. i want to know what the timing should be set at with this change over and if someone can give me a rough estimate on the power i may be making with my set up, the car came stock with the LB9 automatic and 3.42 gears. any info on this is greatly appreciated :hail:

 

i meant to say duration is 212-218* @ .050"

 

The timing should stay at the factory 6* BTDC unless you can burn chips, then you'd play with your base timing and see where it likes it best at idle.

 

a friend of m ine told me last night that the cam i have for the 305 wont work, he said that the 305 will only take up to 480" lift. is this true or can i get away with this upgrade???
