SLP Roller rockers vs. a cam?

[01SunsetWS6]

ok heres what im thinking. I want to install the slp 1.85 roller rockers, and if i do it will boost my stock lift to .508 .520 or should i just do the extra work and put a cam in? also once i do this i am going to need a tune correct? right now i am running a slp lid and bellow, Descreened ported and polished maf, hollowed cats with o2sims, and a magna flow cat back.

just do the cam

all you do with rockers is increase the lift though... your durration stays the same... and you get the real extra power from longer durration not just lift...

opening the valves more only does so much for letting more in... keeping them open longer is where the real fun is at, my vote is new cam as well

ok cool any sugestions on cams? i heard the gm hot cam isnt bad, i dont want to go to radical it will be driven quite abit on the street but i definatly would like a nice boost in power and a lil lope to it nothin above .580 thought i think. just would like to keep it streetable. Thanks

Yep, stick a cam in it. If you got the funds, you could do a intake and long tubs while your in there. Do it all at once and get a tune one time.

I have 11 Comp Cams to choose from on my site. I can also get Lunati cams.

lift has nothing to do with lope, duration and LSA does. The rockers will increase duration but its almost unmeasurable.
If you want a mild cam go with a TR224 114 or a 112 for more lope.
Saying you want something streetable is not a good description. my 246 248 .615 .615 114 cam will idle at 900 with the a/c on and all.

ok with that cam your runnig how is your fuel mileage? would there be any problems driving it alot? will i need to put bigger injectors in? thanks

The rockers do increase duration minimally like said above but they also increase the speed of the valve coming on an off the seat. effectively making the engine think it has a bigger cam in it.
I still vote for a cam swap aswell since you have to change valvespring to do the rockers anyway. The GM Hotcam is OK, TR224 is the most popular DD cam IMO, but the GM ASA cam can make similar power even with its moderate lift of .525

You might want to look into headers before a cam swap.

the tr224 or tr224/230 is way more drivable than either of the gm cams. the overlap of the hotcam and ASA's make them idle rough, very rough.
the tr224 is the most common cam made. It is actually small by todays standards but for a DD I still recommend it. I put about 20k on my car when I had it. went 12.28 with 4.11 gears and a ls1 intake. gas mileage was still great

Thanks for the input and yes i agree headers r on the way.
