yer i spoted that before it looks a bit small for the rest off the combo but im still undecided... um so are second hand cams worth lookin at if allways been under the inpresion it not a good thing to by second hand but iv never work't with roller cams so...?

bit big should say um lookin at em now think i will get the performer rpm you are talkin about it looks to match combo well .... im leafin it alone for a few days now got the flew keep f#*kin things up lol allready ordered the wrong rebuild kit keep gettin part numbers and names wrong my bad...

camt get my head arond it the2031 or the2040 both look good i was gonna get the 2040 but the 2031 seem to match the manifold (performer rpm 1500/6500) a bit better i think dont no..? bePart Number: 444225 Grind Number: POWERMAX 2031 (FORMERLY COM

and then i dont need to change rocker ratio ...?

I'd run the 2040, the 110 LCA will give it stronger mid range torque than the 2031.. Which for a burnout car you'll be wanting.

2031 requires 1.7 r/rockers and the 2040 is designed for 1.6 rockers. Although with my 2040 i decided to go for 1.7's which brought lift up from .498" to .529".

i want to run the 2040 but it requiers 1.60 rocker ratio and i was under the inpresion that 5lt run 1.70 ratio so iv been told...? i dont have anoth money to change rockers ect...

Fuuck me who do you listen to ??
Only the TE50 run 1:72 and GT's / Sprint..
Std 5.0 run 1:6 pressed steel rockers...

lots off people out there drible;in crap lol i research every thing my shelf before i buy just to make sure ... well that decieds it 2040 and performer rpm it is ... now for the rest lol...
