Well the subject line says it all, i plan on swapping cams this fall and am interested in hearring some other opinions.

Here is my current set up- 87 iroc, rblt 700r4 with 2500 stall, 3.42 gears, hotchkis control arms

ENGINE- zz4 short block, old style Trick Flow heads( 1995 vintage) slp t-ram intake, ls1 injectors, 1 3/4 slp headers, slp cat back , random tech cat, 54 mm throttle body, ed wright chip.

Current cam- crane hr-276-2s-12 ig
I=.488, 214 deg @ .050
E=.509, 222 deg @.050

The current set up has run a 13.24 et @ 103 mph ( has been to the track twice, total of 4 passes). When the motor was new it put out 298 rwhp and 362 rwtq, but the af ratio was around 15 to 1.
I built the car several years ago hoping to run mid twelves around 110 mph, but its not quite there. Any suggestions will be greatly apeciated.

 

TPIS ZZ-9X. If you put a stroker crank in it then it would really like it.

 

Your ET seems in range depending on track copnditons. . However your MPH is way low for 300 RWHP. I'am running 102.25MPH with 256 RWHP and a heavy GTA.

 

Yea I know the mph was pretty low, thats why im leanning towards a more agressive cam. One possibility for the lack of mph could have been the tempature at the time, about 90 to 95 on the asphalt and the t-ram intake is a giant heat sink. Typically the inlet air temp rises to about 145 deg if not given time to cool wich was the case before each pass. During normal driving conditions (not idling stationary) the inlet air temp stays around 80 degrees.
