Post is very encouraging as I'm hoping to match those TQ numbers down low, my heap spends most of it's time booting around town or on the highway. I don't wind it up to more than 5k rpm very often... no need. Rev limiter is set to 5500. So max HP not a concern for me.
I'm up at 5k ft. elevation and it's possible I might hit it with EFI. Getting and keeping the carb dialed in can be a chore. Seeing the diff between the 2 carbs is very helpful. I have a 750 DP I pulled off my 390 I was thinking of tossing on to see if it made a difference. Not going to bother now. OP just saved me some tuning time. :thumbsup:
I'm picking my ride up from the transmission shop on Monday, 727 was bleeding. My 360LA has the midler 268H cam (.450~.450) and less duration @.050 to boot. Will be replacing the original cast heads with a set of Speedmaster 63cc closed chamber, 1.6 ratio Harland Sharps rockers (will add .030 lift)and an Air Gap intake topped with a 625 Holley vac. sec. carb. CR should be just under or at 9:1 with a stock thickness gasket.

If I can come close to the numbers in the OP's build I'll be very happy.
