The bleed down lifters will help bottom end and make the 3.55 gears pretty nice for city driving.
Not trying to upset, nor steal this thread, but I have a 428 in my '66 GTO, with a 3.55, P275R/15 BFG's, and am curious about the "bleed down lifters". What are they, and how do they work/help, and without pulling the engine apart, is there a way to tell? And sadly, I don't know what cam is in it! But it has a nice rumpity, rump sound and decent pressure from exhaust . Doesn't tell much does it? Seems to have decent low end power with an Edelbrock & Torker. But, as we speak, I am having a brand new tri-power set-up installed, new distributor, along with a Tremec TKX 5 spd.
My Christmas present to myself!
Only had the car about 7 months. Sadly a previous owner's "ex" trashed all documentation, pictures, etc, of the restoration, which is about now 12 years old.
You guys are great with suggestions, ideas, sharing of experience, etc. And any advice is appreciated!
