Thanks - does the lower compression work better with the 110 LSA vs the 113 in my HR242 cam?

The 113 is just going to push the power band a little higher and spread the curve out. Not a bad thing. The bonus is smoother idle and more vacuum. Should run brakes fine.
My 242/248 was also on a 110 and it worked brakes marginally, I added an extra vacuum canister and drove it like that for nearly 25 years.
Dad's engine with the bigger 254/262 on a 110 didnt run brakes that well. He used a electric pump for a while but eventually switched over to hydroboost.

Another is the 455 I built for a member here. It is 9.98:1 compression and I used Paul's custom spec'd 239/243 @050 with a 112 LSA. It is also over 600 lift. That engine was built to appear stock. Stock aluminum intake q-jet RA manifolds etc....and made 507/571 on the dyno Paul uses with a really nice flat torque curve. That car drives like a stocker with a nice snug-ish converter and 3.42's and runs the power brakes and AC. A very nice well manored driver that should go into the 11's.
