My Ranger Is A Mustang At Heart! Help?

[90Ranger302]

Hey everyone I could use you input, since I am at best a novice.

I have a 1990 Ranger that I rebuilt the 302 in that I converted over three years ago. Here's the setup.

Stock bottom end

gt40p heads stage 1 port

Crower 15510 cam 212 duration .531 lift

1.7 Rollers

Aod tranny with TCI valvebody and 2600-2800 stall converter

570 Street Avenger Holley carb

Sanderson headers 1 1/2 primaries/ dual 2 1/4" pipes to converters / balance tube after converters / Flow Master Mufflers 40 Series / dual 2 1/2 pipes out the back

3.73 gears

This combo just does not seem as strong as what I thought it would be.
Timing is set at initial 10 degrees with 42 degrees coming in at about 2600 rpms.

Is it possible that the 1.7 rockers are giving to much lift should I go back to 1.6 rockers? Or is the carb not big enough, I have a 4160 also I did not think it would that much gas though.

Any thoughts ?

Thanks

The Flow Masters give it away now. It has a great tone!

I forgot to mention the intake is a Action Plus

I'd check the compression and valve lash. Too tight of a valve lash and the motor will be lazy. Uneven compression will obviously lower the performance.

What benchmark are you using to say that it is not as strong as you thought it should be?

One more question. Positive traction or open diff? If you spin, you may not be pulling as hard as you should.

To directly answer two of your query: The carb is big enough. People tend to over carb and kill the responsiveness of the motor. The rockers should not be hurting your combo any.
