630I Cam Specs

[WhipLash96]

Does anyone know what the cam specs are for this cam? I'm looking at the BB Cam Comparator and I see specs for the 630 but not 630I. Are they the same?

Thanks

23/51, 254° duration, .630 lift intake
62/18, 260° duration, .610 lift exhaust
108° lobe center, 41° overlap

LSA?

LSA is the lobe center #.

Are those specs for opening and closing at .053 or ?

Most all HD cams are listed at 0.053" at the lifter. Only Leineweber uses 0.020" lift. Maybe original older Sifton cams were at 0.050", but later were 0.053"

.053" found here.

id go woods tw9bg , i run with a +2 key but just my opinion , i just dont know alot about the strange exhaust timing not sure how that all works together with the heads and valve sizes , but i do know the woods cams work , well for me they did , loved the TW8G 590 lift but a little short on a 117" , i like the Tw9FG with +4 bad ass but need compression, run a Tw9BG with +2 on a 11.1 runs great

" i just dont know alot about the strange exhaust timing not sure how that all works together with the heads and valve sizes , but i do know the woods cams work , well for me they did "

But all of that is important as is and especially the pipe and it's relationship to the Lobe center placement, Lobe separation angle, cubic inches, maximum rpm, and the added exhaust duration, if present. Bob, glad yours works well but playing the good cam bad cam game is a crap shoot for many. Good cam brands and not so good, same deal, most are ground by Andrews with lobe tweaks by the vendor and Andrews' designer. To the OP, how lucky are you feeling? If you saw some other dynos with the 630i or TW9b ("good cams")will you duplicate those results?
