I am building a cleveland for my '67 Falcon, primarily for street use and a bit of track time. I am looking at one of Howards .875 specific solid cams, 236/240 .621/.638 on a 108 LSA, 104 ICL. The motor is a '71 4v with flat tops and will be right around 11/1 with a cold air setup. My EA is indicating an 8.18 dynamic compression ratio with 211 psi cranking. The car is fairly light, and will have either 3.89's or 4.10s, 26" tall tires with a 3600 stall converter, so it will flash past peak torque fairly quickly and wont be lugged at all, I have Chevron 94, and am fairly comfortable that this will be ok on my fuel, but its probably on the edge. I am currently running a 355 chevy at 11/1 on this fuel with 8 degrees more intake duration, a 110 LSA and underhood air, and it is fine on this fuel, has never rattled.
Heres the thing, I have been reading the thread on Speedtalk on Vizards "magic" 128 method of LSA selection, using that formula, it indicates that the optimum LSA for this combo should be 110. But virtually every solid cam I have looked at over the years for a cleveland is on 108 (except for Comp, and they just automatically default to 110 for every street/strip cam in their catalog

) I cant help but feel a little sceptical, especially considering that 98% of what Vizard does is small block chevies.
Assuming I install the 110 cam 4 degrees ahead like the 108 version, spreading the LSA 2 degrees would back the cranking compression down a bit, and it would idle like a real pussycat, which is attractive to me. The cam is probably a hair on the small side for the combo, and delaying the intake closing point may make it hang on a little longer on top, but I do not want to do that if its going to give up torque in the 4000-5000 range.
Anyone have any thoughts on this? Any engine builders on here have dyno time comparing 108 and 110 LSA's in Clevelands?
