I spent every weekend in the garage last winter meticulously putting everything together with Mild Thunder.
As an example, I had perfectly good Scorpion rockers and swapped those out for the offset Crowers to get a better valve pattern.
No crappy assembly or junk parts here.

Yup, I don`t cut corners and I didn`t build em with selling in mind. Just that`s the way it turned out.

When I say offset , I mean the backset ..
When installing a .100" long valve, the rocker arm
tip must be backed up .050" to insure centerline
contact at half lift. Crower offsets the rocker
stud hole in the trunnion, pulling the rocker
tip back into correct alignment with the valve
stem. Re-establishing correct
geometry reduces valve guide wear and promotes
more accurate valve timing.

Nice motors and great deal . But I do have a question . It looks like no intercoolers. Why and I may be wrong but I thought I always heard 5 to 6 lbs boost with no cooler or8 to 9 with, before needing race gas. Just curious.

Icdeppls engines listed here, had a wot intake air temp of around 135-140* . That isnt very hot.

I don`t really believe in the marketing and hype of intercooling in a carb set up where most of the cooling done by the fuel.
Intake temps run cool enough for my application.
The tune is key for longevity , that`s the reason I had EGT, AFRs , knock sensors , intake temp, and 3D timing map set up.
