Hey Dave, how aggressive of an engine will a tbi system handle? I assume there is a limit to how big of cam one can use?

I have run a 232/240 @ 0.050 roller on a 108 LSA in an 10.5:1 383 with Vortec heads. 7427 PCM running a TPI with siamese ported SLP runners. Very little difference in tuning that PCM with TBI or MPI.

Using the correct valve spring$ on Vortec Heads when using high lift cam$haft$ is an important topic: https://www.hotrod.com/articles/vort...pring-upgrade/
