Re: Personal 380 SBC Dyno
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! LOL

Re: Personal 380 SBC Dyno
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.
