400 stroker rookie

Not disputing Andy or IQ52 at all, I would use the trickflow heads if I had to buy a set. I have fully cnc`d (standard port) alum. victor knock offs that flow the same at .600 as the stated max wedge trickflows do. So far so good----------
But they do require offset intake rockers, and special length pushrods. We changed the retainers and keepers also/springs checked good.
In a 68 barracuda body, they are kind of a pain in the a--, absolutely no room for "any" heater motor in the firewall. An aftermarket , under dash will work for heat and defrost only, and be lighter too.

My stud girdle was 1/2' also, I had it cut down to .300, wish I `d went to 1/4'' just for the weight.
Sounds like ur on the right trac-------------
400 block is stronger than a 440 block------- Thetre are 4-5 guys on here that really know their ---- not me, I read everything they post!
