Anyone tried or know of the Rollin Thunder RPm cms from Edelbrock? Im leaning torwards the 220/224 510/510 111 LSA, starting out with the TB converter till I get a Yank or Circle D, anybody have any experience with these cams, and ball park figure I can expect to gain in the 1/4? 14.007 now with stock cam and stock converter.. thanks guys

That is not a bad cam especially for a 5.3 but I would look at getting more lift.

i noticed the lift was lower than other cams with the same duration

I would say get one speced from Patrick G...Spend $25 tell him what you are wanting and let him work his magic. I think in the end you will be much happier. Off the shelf camshafts are great but one speced out for your combination is better.

will look into that, basically im looking for a great cam for track/street use, good manners with a choppy idle

As I am sure others will say. Even big cams can have good manners with a good tune.

What are all of the modifications that you have done to your truck? I personally wouldn't bother having a cam spec'd out unless you have a lot of internal engine mods, running boost, or spraying nitrous. There are plenty of proven cams out there for just the basic bolt-on 5.3l if that is what you have. A couple of things that you might want to consider when choosing your cam: your future mods (such as FI), how high your going to spin your engine, and also how big of a stall converter you are willing to run. I personally run the TSP 220/220 w/ 112lsa and am very happy with it. IMO just do the cam swap and drive it until you have the money for the circle d or yank converter.

headers, tune, truetrac with 3.73s, thats about it... im going to stick with n/a, and will be running a tb converter for now, till things get better and get a 3200 up, so i was thinking the tsp20 or 224, agressive idle comes from the lsa correct? so maybe a 110 or 112? thanks for the help guys

id go tsp220 cam, the 224 wont make any more power then this one till after 6500 rpm. and a 112 would be good on the lsa, the 110 will shake more at idle and be a bit harder to get a good idle on but if you have a good tuner that shouldnt be a problem, the 110 lsa makes the power come in a bit sooner and be a bit snapper, hp wise it wont change much.
