Im adding 1.6 SA Full Roller Rockers with the whole LT4 spring setup to my LT1. (no cam its stock) with the mods in my sig what do you think my gain might be?



Thanks

 

I did my headers, ORY, and dumped bullet, and !70# of RW at the same time I did the 1.6 full roller rockers and lt4 spring, retainers and etc., so my results are a bit better then average...

I went from running a best of 13.1 @ 103, and an average of 13.3 @ ~102 - 103 to a first time out shakedown run in my sig. Too bad I only got the one run in and it was the last day Maple Grove was open last year, I know there was more in it...

But, I got more then a .5 reduction of my best (> .7 from my average) ET, and picked up 2 (almost 3) MPH, and BTW our mods aren't too far off...
