what do you want to know? Rear end can fail on stock cars.... weakness with the spider gears. Some run all kinds of mods and hp, and haven't had any problems, others have failed with a lot less... Just depends on how hard you treat them... I ran the roadster with the dual cai, pulley, tune and it was fine when I installed the wavetrac. I installed the wavetrac for better traction and better handling... You may be fine without it, if you don't run slicks... dual cai, will net a little more hp, better acceleration. The pulley, more hp, more acceleration, the tune, just brings it all together a/f wise...
oh, about forgot...this motor is 349 hp stock at the crank...you will be in the 370+ with the above mentioned mods...
