Sam,

Let me say that almost everything that I can think of has all ready been said except this!

The L-88 cam is marginal at best in a 427 in the street and you're running 31 cubic inches less.

The cam was designed for headers.....no doubt about it! Wayne Nelsons L-88 corvette that just went 11.99 at Stanton 2 weeks ago dynoed the motor at 571 hp at 6700RPM with headers.

With the manifolds it pulled down 505 hp @5800 RPM with 480+ lbs. Wayne shifts at 6100 RPM because he is going slower and wasting motor if he goes more with the manifolds.

Are you ready to have the neatest sounding car but get beat by an average Joe because it wont run strong except the last 2000RPM before redline? What you have read on the above posts are the truth. Do you want to go fast or have a neat sounding car?

As far as running some of the really fast ramp lobed cams, the valve train must be in good working order. Lots of spring pressure must be used to keep the valve train stable at high RPM. Find a good machinist if you go that way.
