1.7 Rocker Arms Advice With My Setup

[from6to8]

I have a 95 GT with Crane ( E clone), Edel performer rpm 2, trick flow twisted wedge heads, 24 lb injec, Mac shorties, Basani X with 2 chamber flowmasters, 1.6 FR roller rockers, 255 lb hr fuel pump, 3.55 gears. I was thinking about going up to 1.7's to help with lift and see if it would wake up my car's low end torque and hp. I just put a timing chain and fixed TC cover gasket leak and I hate to have to do all of that to change the cam and possibly have to mess with pistons or get new pistons right now. I am basically trying to work with what I have and doing the rocker arms I can probably do that myself. What are you guys thoughts with my setup and the 1.7's helping or not, and how much can I expect to gain?

The 1.7's will raise valve lift from 0.498" to 0.529" and you might gain ~5hp.

It won't hurt, but I don't think you'll see a whole lot of gain out of it. I remember running 1.72s on a Steeda cam way back in the day to get a little more lift. Not sure it would be worth buying rockers twice though.

I heard maybe somewhere in the area of at least 20 hp. Are you basing this off of your stock setup with going to 1.7's. I think i was reading with a stock setup and going to 1.7's the gain would be nowhere near what it would be with an HCI combo

20hp sounds a little steep.
