Regarding the below excerpt from your other thread, how do you think using the stock 2.2T heads would effect things AND can you please also comment on using the T cams OR using E cams?
The first two engines I built with E cams were pretty similar except for the induction and port size. The first had small ports and MFI and the second had big ports and Zeniths. Second engine made more power and torque everywhere with larger ports.
My take away from the various builds is, go with bigger ports, use modern cams.
I would not use factory T or E cams when much better cams are available.
I am using Zeniths on my current 2.5 with PMO manifolds. The stock manifolds do not have enough material to bore much larger to match the intake ports if enlarged. I would enlarge the ports on your existing heads and get appropriate PMO manifolds to match.
You can get different chokes and jets to have your Zeniths match your engines needs from multiple suppliers (see Alpha1750 on Ebay). Air correction jets at high RPM seem to be the biggest limitation with Zeniths.
With the cost to build these engines I would not skimp in two areas that for me made such a big difference in power.
