interesting now that all of the figures are out with the op cams.i need to ponder them more.
[I checked your numbers and your first 254/110LSA cam has 39* overlap.
your new cam 252/113LSA has 30* overlap.]


for my cams the 110 cam would not make boost past 8 psi even at 25% OD on the blower it quit at 5%OD.[10.90/? with the 113 cam the carbs held it back at 10 lbs at 10%OD[10.41/129
the cam in mine now is .646/.631 291/306 @ .020 260/269 @ .050
.050 in op 21 cl 59/exh op 69 cl 19 with 40* overlap at .050 without lash on a solid roller[.018 I/E] w 14lbs boost and more.

First, can you fix my error in your capture of my quote. I stated 242*"incorrect" instead of the 252* for the 113 LSA cam.

Second, Im a NA guy and not a boost guy so Im just bench racing for the OP, because he"s a local guy. So as not to hijack his post, "more cam thoughts" But Im going to include yours.


In requards to your opinion of not using the 108 LSA, Id like to ask your reasons or reasoning in this case.

Also, I cant explain your boost differences. Wheres the boost being lost? Not in the overlap,IMO So where? Let me lay out your 3 cams along with the OP,s 108 LSA cam in a comparative way to see if it helps.

duration .050---LSA--OL--boost---OD%--IO.BTDC

OP,s 240 @.050--108--24-----NA--------12*BTDC

MS,s 254 @.050--110--39----8psi-25%---17*BTDC

MS,s 252 @.050--113--30---10psi-10%---13*BTDC

M,260/268@.050--112--40---14psi-NA/%--21*BTDC

Not being a blower guy, I dont understand the boost problems between the 254 and the 260/268 cam. What are your thoughts.
