For stock engines, the change is small enough that the stock computer should not have any problems. Its effects are greater if you have enhanced other parts of your intake.

I've been running a set in my 87 GT (SD computer) for a few years, and I've had no problems. The engine has a larger throttle body and 1.5" aftermarket headers, but is otherwise stock. I will say that I noticed a drop in power when I switched back to the stock throttle body. I don't drag in the streets, but there is an on-ramp I'm very familiar with, and it's definitely taking me longer to get up to speed with the smaller TB. So my feeling is the 1.7:1 rockers by themselves have very small effects on power.

Ford found a 15 hp increase when they used the full roller 1.7's on the Cobra 5.0. Some came from the friction reduction in the switch to the roller trunnion, some from the increased valve lift (.030 at the valve) and the stiffer rockers (no deflection). They also lowered the oil temperatures. I've used a set now on 5 different engines (same set) that had over 100K miles on them. They seem to last forever.

This is good information guys it confirmed my ideas on this build I’ll post my material list when I get my heads it’ll probably be similar to Dave’s list. If I start going in the wrong direction please let me know

1. 35-308-8

2. 35-320-8 not sure if SD works here or mas air

I would use Comp's springs instead of Trick Flows. Also a plain jane Cloyes True Roller timing set for a late model roller 5.0 will save you money I'd bet. That's what I put in my 331 14 years ago ($25 at O'Reillys) still on the job too.

That's not a bad price then. I recommended the springs because the rates may be different. Just make sure they're close in specs if you're going to go with them.

Have the rods resized on the big end when replacing bolts. On the crank journals, inspect for any nicks, other damage, hot spots, etc. If they look good just mic. them in a few spots to make sure they are round and within specs.
