Cam to be hyd. roller w/ 228@50, 525 lift ( w/ 1.6 roller rockers ) and 106 cl. 1 5/8" headers into 2 1/2" flowmasters w/ crossover. As a street toy, I want the thump for sound effects and from the light, when the loud pedal goes down, I want everyone way back in their seats. I was told that the 170 heads and the 650 is best for low end as well as the duration on the cam. I hope the 106 cl will give me the thump. What do ya think?
You don't say what the comp. ratio is.
To run a cam like that you will need more than 9 to 1 for a comp. ratio.
Everything looks well matched.
