32k mile 6.0 out of a tb ss. looking to cam,pushrods rockers and valve springs only. have a ported vic jr and proform bodied holley 750 dp for the time being...

car-67 camaro. aprox.3150 lbs with driver, richmond 4+1 tranny and 12 bolt with 3.73's

i dont fear overlap. my last thrown togather 357 had a comp 306s in it (555 intake and exhaust,260 260 duration @.050 and 110 lc) in a 10 to 1 motor. went high 11's in the above car @ 3360 lbs.

not looking to touch or change the heads.

 

45 views and not one reply?! really?

 

ok since i got no replies i made a bunch of calls and everyone seems to be in the same ballpark lift and duration wise, but from 110-114 on the lsa...

anyone have a manufacturer that seems to work best? i called

ultradyne
eps
cammotion

 

Is this a race only application???
I hate to be the bearer of bad news but your previous ET is not very good with a cam that big, if the specs are correct...260@.050??

 

EPS has got some real good reviews.
There are guys going mid to low 11's on 220-ish duration cams. Something seems "off" in your combo to be going high 11's with a 260.

 

it was an old 23* headed motor, the heads looked like steevie wonder ported them with one hand,and i had less than 300 bucks into the motor from intake to pan lol. the duration was huge, but i think it crutched the horrorible heads lol.

that motor shouldnt have gone faster than 13's probably.

 

I am interested in your findings. Seems everyone building carbed setups uses off the shelf or used cams to keep in a budget. There is not a lot of information on "carb" cams out there for LS stuff.

From what I have read looks like a wider split is favoured by the vic intake but i cant confirm anything. Let us know what you end up going with if the cam builder allows the information out.

 

Based on my recent experience. I would say between 230/234 - 234/238 on 110 LSA with a 108 ICL. I would not go bigger unless you had more gear and want to spin to 7000 RPM.

 

i am waiting on my recomendation from patrick g. every manufacturer was too all over the place from the next one for me to make a good call as to what would be best...

comp told me a cam that was 113+4...and 621 624 lift. really? in a cam only carb app that i said i wont flycut for?

hopefully patrick can set me straight with this...

 

i dont mind shifting it at or near 7k...but i dont want it peaking there.
