Is this a different engine combo? Is it still a 4speed?521 CI RB, TF 240 heads opened to MW, 370 cfm@700, 11.25 CR, 337 ported intake, 268/272 at 50 roller cam, BAM lifters, 2" Doug's D452 headers, CZ vacuum pump, 1050 Dominator, Air cleaner lid flipped over.

Hey! it's got a Passon 5 speed in it now. I had a pinhole in the oil pan, so the motor had to come out, decided to raise the CR and go roller while it was out. Was trying to keep the same dynamic CR with the new pistons so bumped the cam up. Going from 260/264 to 268/272 raised the minimum cruising RPMs from 1500 to 1800. Still running 90 octane non ethanol pump gas with 11.25:1, so that goal was reached. After helping a guy clean cam grindings out of his engine, I thought I'd bite the bullet and go roller, save that headache in the future.Is this a different engine combo? Is it still a 4speed?
I have one also still in my 96 Ram.
Your vacuum advance is hooked up backwards to the wrong port SPECIALLY in the AZ heat.... And you'd see a HUGE improvement in driveability & power with a Holley based carb. That Weber/Edelbrock is not a good choice in the any warm climate as they barely hold any fuel so it's surely preheating the fuel....
