bought a speed inc si6 cam 235/240 .621 .609 btr dual springs 7.4 pushrods ls2 timing chain to go with my pi 3600 vigilante converter and ls6 intake im getting excited to get this done

 

Make sure you check piston to valve clearance. Should be a fun ride when done

 

of course i will check ptv clearance hoping i will not have to fly cut as speed inc told me it will not be necessary with stock heads which is the only reason i went this big

 

I had a hair milled off mine at the time and ran a 238/242 when I pulled the motor down to go bigger there were marks on the pistons where the valves just touched a few times...I got lucky and didnt do any damage

 

Mark what was the full specs of your cam?

 

With that cam I would run a 4K stall to maximize performance.

 

I would run a 4k+ stall as well, and I do, with a smaller cam. but Adam has his mind set on a pi3600, it probably stalls a lil bit higher than say a ss3600 so he will be fine. little bit More wife friendly and more street friendly with the 3600

 

I think I'd run a 4,000 stall with it too.

Mine was a 238/242 .595/.595 112 lsa. Now I jumped up to 255/277 .624/.624 115 lsa that pulls hard as hell all the way to my 8,000 rpm fuel cut.

 

installed my pi 3600 vigilante and its loose as hell and flashes about 4000 rpms at wot so all should be good under the hood
