They are lumpy old school, No bottom end torque, goodness

And VERY easy on valve springs !!

I run a 140 with 1.7 rockers in my 72 nova 350 flat tops zero decked with 4.33 rear and fast burn heads.
11.60's @ 113.
Definitely needs good fuel. I add a couple gallons of 100 LL to a tank of 91.

Read that whatever way you want...

Jump in? I didn't ask about Lumpy sounding cam for the LT1. You jumped in with if someone wants a lumpy cam... so your post wasn't related to my initial post was it?

I appreciate all the other suggestions here guys Lynn I'm leaning towards the LT1 cam but was initially concerned about LT1 detonation as the 302's kind of missed that with the stock cam, right now my 302 with 3.31s and stock exhaust manifolds is a bit of a pig to get moving

Yes...it was actually. Many of the cams that you were provided including the so-called "several" I suggested were very suitable choices for an LT1 build. The roller cam I suggested with its 236/240 duration is an excellent hydraulic roller camshaft for an LT1 and makes enough vacuum to handle power brakes as well as support the RS headlamp operations. You did also say in your original post that you had no issues with a roller cam...did you not?

I have no issues going back flat tappet or even a street roller

Well? That was a really good street roller. If it's a little too lumpy for you, then understand that the entire line of hydraulic rollers is easily bumped down a step or two to what becomes a very mild-mannered street cam, and is totally forgiving on the valve train. Something the guys at Crower could have easily helped you out with. Seriously...they work with everyday people to help select camshafts all the time.

All snide aside...good luck with your engine build.
