i turn mine 6700 to 6800 easy.

 

guess ill drop it down to 6500-6600 instead. booo lol, cant afford much **** right now.

LS1 Comp Cam 228/225 .588/.569 112LSA <-- the cam
and its a 5spd...screw autos

i could get different springs though i suppose. paying $150 for the springs and $185 for the cam. if i could ever sell my RC Car i'd get better springs and retainers...maybe ill just buy the cam off him and wait til it sells

so what springs should i buy?

 

918's

 

918's are what im buying

so im just gonna get the cam, springs, and pushrods and set the rev limit to 6600 for now. figure id never fall below 4k rpms shifting gears so ill be ok.

should be getting the cam and springs tomorrow, gonna order the pushrods also....tahn its just installing them and getting it dynotuned

 

we have customers that turn 7200 with stock valvetrain and ls6 springs with no problems. cams are in the 240* duration .540 lift. we do use arp rod bolts. these motors are 5.3L's that run 1/3-1/2 mile oval tracks. our motor has 3 yrs on it with 6800 rev limit. same cam specs.

 

i thought that with the short stroke the 4.8 was able to rev that high, with the proper cam and valvtrain, and rod bolts....ive read a lot of conflicting information on this forum. the poor 4.8 gets no respect.

 

i have a set of hardend pushrods for sale in the classifieds if your intrested

 

the 4.8L can rev that high. on a regular basis with daily driving though, it's still only stock. it will give.

 

Shaft mounted rockers, or a girdle, Patriot performance gold double springs

 

if those cams with 240 are @ .005 it is alot smaller that the one he is putting in plus they arent lifting as high either and I bet those lobes arent xer type either I think its stupid to not put in some heavy springs with that aggressive of a cam and those high rpms its like asking for problems. The reason I went with 918's is because I have a cam with symmetrical lobes and I shift at 6200
