I added the 52tb and 1.7rr together (360/5yrs ago) and it gave a real nice gain. Very noticeable. Already had all the best bolt ons and m1/2bbl and mild cam when I added them..

I have the HS 1.6rr on my Eddy heads with Hughes rocker girdles ontop of the 408

 

i have all you mentioned, and i liked the gains from the 3815 the best. and the 1.7's were the last thing i did. and i would say 10-15 hp on the rockers is pretty accurate. and about 20-25 on the superchips,unless you are deathflashed. then expect a little bit bigger gains.

 

how bout you order the 'SEARCH' feature, that will give you bigger performance gains, along with less pissed off forum veterans





DISCLAMER: Not responsible for faulty power gains of said product or the veterans still being pissed because your a n00b, void where prohibited, no purchase required, may increase transmission and tire wear, gas mileage may drop, plenum may leak, your girl may leave you because your an idiot for purchasing, genital warts, or crabs may randomly appear.

 

I found a set of 1.7 for a banging price. Not sure if I should buy them or not.
