Good thread and a lot of good information. However, I feel you need to match the cam with the parts you are using and you will generally need a tighter lobe separation than 114 if you're looking for cutting edge performance. However, I cannot stress how important it is to match all the components! The new norm is 10 second naturally aspirated pump gas street cars.

In 2006 I was running my 80 T/A with a 9.1 compression 455, ported cast iron heads, 3.42 gears, tight 11" Coan 2800 rpm converter and a Comp hydraulic roller 242/248 with an 110 LSA. Weighing over 3900 lbs. the best ET was 11.35 @ 119.3 mph.

For the last 2 years I've been running the same 3.42 gears, the car has lost 100 pounds and uses 318 cfm E-heads, Torker II and a tight 10" converter with a solid roller 259 @.050 on a 108 LSA, I've only had it to the track 3 times but have run consistent 10.7 @125 mph.

A friend was running a 9.1 455 with E-heads, 10" inch converter and 3.55 gears in a '64 GTO weighing 3670 lbs. and has run 11.2 @ 119 mph using the dreaded Comp XR288HR which has a 110 LSA.

My brother ran a 9.1 compression 455 with 310cfm E-heads, a solid roller with 254 duration @ .050 ground on a 108 LSA, and went 10.8 @ 124 mph the first time out, using a tight 10"
converter, 3.70 gears and weighing 3720 lbs.
