they're intended for a stock 103 but add a few points of compression above stock and they should shine. I wouldn't go above 10.0:1 but that's just me wanting reliability and nil probs

 

My andrews 57h with the headwork and 107 cubes run very strong.

It's also a very smooth riding bike.

Wife and I can log hundreds of comfortable miles on it until I snap the throttle open. Then it slings you back into.

 

Here is my 110" with Andrews 57 and sitting at 9:7:1 comp. the curve is a little shaky becuse the guy tha tuned it was not the best at the shop. I am gettng it remapped by a more competent tuner. But you can see the potential.

 

 

right in the middle of 107 with 57 cams stage 2 heads from hillside. cams and cam plate in oil pan off and totally flushed out, crank case vacuumed out . starting with a totally clean inside, figure for the 12 buck gasket and 3 hours of extra time may as well clean out any old oil and inspect what came out before I add all the new parts, polishing cylinder fins tonight , clean cylinders up and install pistons cylinders heads by the weekend, getting rocker lockers, noticed rocker pins starting to move in the cradles , then drive for a cpl months hope to get back to hillside by july for dyno.

 

Holy necroposting. Tha tread is 14 months old.

 

Don’t ride it for a couple months before tuning!!!! Hillside will agree. Nothing worse for an engine than breaking it in without a tune. It’s WAY too big of a gamble.

 

& still very relevant.

 

I have this cam and it leaves some on the table...its all done by 5700rpm, duration puts it in the mids as does the 38 degree intake closing. The lift also leaves a bit on the table. More of a all around cam.

 

As was mentioned in the other thread where you posted this chart, SAE correction would probably put hp a bit below 100 hp, plus the possibility the dyno used could be a little happy.
