Personal 380 SBC Dyno

Post by cspeier » Tue Jul 25, 2017 9:47 pm

So here is my thought as I started reading....

I saw "33 Ford" and I thought, "cool... mild street rod cruiser type combo." Then I started reading the specs! :eek: LOL

The shaped dividers in the intake floors are interesting.

Cam looks like it'll live a long life, pretty mild on the lobes - low maintenance engine?

Did you try winding the cam back to 103ICL? - I reckon it may be happier there, but I may be wrong!

Big spread from peak TQ to peak HP - she's not head limited, it'd go more rpm up top if you wanted it too & cammed it up.

I can see 700hp pretty easy with another 4 deg duration on both sides, 103 ICL & slightly more aggressive lobes - say .430" lobe lift.

It's a damn good starting point as it sits!

Would be interesting to run it on E85.
