Big Block Advice Needed

Thanks for all the advice. To clarify, I am not talking about going to a bigger solid cam, I am talking about a similar sized solid cam for a few reasons. Added stability at high rpm, between my 4200 launch and 6000 shift, where hydraulic cams suffer, solids with a similar advertised duration actually have a shorter duration due to valve lash, and going solid will require me to use my crane rockers which have a true 1.5 ratio versus the factory rockers currently on the engine which in reality are more like 1.4 or less.

I agree that the performer rpm is a great intake…… for a heavy street car with a tighter converter. Again, I am reasonably light and am looking for gains above 4200 where a good single plane or tunnel ram should come out ahead.

Yes, roller cams are miles ahead…… but not currently in my budget, LOL.

I am looking for some real world and experienced advice from someone who has run a flat tappet and tunnel ram.

Thanks all!
