thank you for all the responses and the warm welcome,
but unfortunately i have clearance issues with going any taller on the intake. i already have the lt1 intake manifold that i plan on modding to work on the gen 1 small block (modding mount holes, modding it to fit the gen 1 distributor, and adapting it to work with the correct coolant passages.) i plan on using my megasquirt on this to control fuel, spark, and nitrous.

my question is only between the IROC TPI intake and the LT1 tpi intake which one flows better?

thanks,
Jessie

ill get pics up soon
