Just a little 470" here. Had a single plane and big solid cam (gave it back to AndyF, it was his dyno mule short block). Didn't "turn on" till the revs came way up. Not fun. It's not a race car.

Changed to an Edelbrock dual plane, 850 Race Demon with annular boosters, an old skool MP528 solid cam, 1-7/8" TTI headers, 2-1/2" exhaust, Edelbrock heads max ported by late Jeff at Modern Cylinder Head, Passon alum case Hemi 4 speed, 354 gear. Talk about tire boiling fun but still with manners tame enough to drive to the local grocery store. Still has a very noticeable idle. I'm getting older (57) so swapping to exhaust manifolds and Borgeson power steering

What are your 541 specs?
