This little engine was so neat I had to post it. It is a daily driver, 352 + .062 overbore. Low lift, short duration, 16” idle vacuum. 3x2 EFI on top of the new BBM heads, cnc 2.100 intake ports. Static CR is 9.2:1 and built for 91 octane California gas.
We made 438 hp/456 torque with dyno headers. We swapped on a set of Kugel Komponents cast shorties at the end, as that is what will be used in the ‘65 pickup it is going in. It didn’t hurt it much, and would likely be even closer, but they had a hard bend in the 2.5” pipes between the headers and my exhaust tubes. Still had 415 hp/ 437 torque!!

Dyno headers and Kugel Komponents cast shorties

Looks like a really cool build and would make a nice commuter and still fun to drive. Really neat seeing the real world difference on those Kugel cast headers. Surprisingly good when you consider dyno headers are usually better than any of the chassis headers to start with. Been considering a set of those Kugel's for my near stock 390 in my Galaxie. Like them even more now.

those shorty's didn't lose too much to full headers, 18 horse for the cool factor is worth it on a 62-61 Galaxy .
Blair how much more power would a single 4 make over the 3x2 in this application ?

Will the Kugles fit in a 66 Galaxie? That's a very cool build.

Eric, I don’t think a single carb would be as good in this combo. The 3x2 manifold is sized pretty well for an engine this size, and the injectors in those three throttle bodies are tuned individually. We checked AFRs in all eight cylinders, and we were able to get distribution pretty darn nice in this set up.
It only has 222 duration at .050. It’s designed to run DAILY. If it was a toy, I would like to see what would happen if we threw some camshaft at it……

killer little engine, i will be coming down from kingsport soon to see you.
