I posted this in another forum & got no answers so maybe I had it in the wrong forum! Hopefully this will be the right one!
Has any one used the comp xs290s cam in a 440 bracket car?
I think im going to give it a try. I need to ring and bearing my engine so i was told by
comp that it was a good cam all around. Thinking about advancing it 2 degrees to bring up
running compression a bit. Along with a thinner head gasket, and taking a bit off the heads.
The dynamic compression comes out to 8 to 1 the way it is. I m not sure but i think it
would be better around 9 or 9.5. This is a race car only so it will be run on race fuel.
I have got the 26120 comp bee hive springs so its limited to under .600 lift.Does any one
known where the running compression should be? The car has run a best of 10.56-127mph
Thats with a comp 21-626-5 cam in it, .562 lift,
[email protected]. I am running 1.6-1 rockers,
Victor heads,1050 carb,victor intake,0.030 over flat tops at zero deck height. 11.3-1
let me know what you think. Thanks.
