Best bolt ons for a small block

Post #93/4. It means 114 LSA is a loser.
Yes, 109 LSA is better.

In D. Vizard's SB chev book, he lists cam for various performance levels. Yours might be Quick Street. Guess what? From 302 up to 434 ci, each cam has the same 224 @ 050 duration. How can that be? The LSA is different & therefore the overlap; 110 LSA for the 302, 104 for the 434.

I s found that the 224 @.050 is about the ideal duration for a really nice street set up as far as a driver with respectable power returns. Of course the rest of the combo is responsible for what the final outcome is or could be. An engine with stock heads & intake will be low powered while a ported iron head and upgraded intake releases more power and a well ported head and intake offer the maximum return on power while all of the example roughly have the same power band. There is just more offered in the higher rpm band with better flowing intake and exhaust components.

Of course not all 224@050 cams are created equal. There precise timing events are different and will perform different.

@AJ/FormS
This is what AJ often writes about. The timing events and the meaning or better yet the inner workings of how the cam timing events better trap the air and fuel for more power.

The better your cylinder head flows, (more cfm and at what lifts) the more lift you can use to get the A&F in the cylinder and out of the cylinder.
