461, fuelie heads without holes, 186 were basically same, w holes. I think there was a 327/350 version 041. All considered 300hp factory heads. I had a set of worked 186 on a 30 over punched 350, 3/4 cam, etc. Had my hands on a set 461 one time but had to let em go. There were angle plug styles & aluminum double humps too, also called camel humps.

Yessir, I’m very familiar. guessing he misread double humps as “double pumps” maybe? Referring obviously to some variation of the 4150 double pumper, but preferred Holley “big bores” guessing a 4500series Dominator.. I SUPPOSE he could be talking about Holley heads, but I’ve never once seen a fairly later model Holley Systemax head used in any kind of oval racing.. Anyone competitive would’ve been running a Brodix, Bow tie, or MAAAAAAYBE a Dart… And I’ve never in my life heard a cylinder head referred to as a “big bore”.. Big VALVE, sure. Big PORT, fair enough, but not big bores.

True. The next motor I built was a early nickel 4 bolt main block, 30 over, FT's, Vortec heads, 0.015" head gaskets, single pattern torque cam, 474 lift, high rise dual plane. Quadra Jet mounted backwards. Went in a mud truck. Had crazy pull in it. The Q-jet backwards wouldn't bog because their float bowls are opposite end of a Holley & I wanted the earlier Jet w 780cfm. Damb thing was rowdy on 44 boggers & Dana 60F Dana 70 rear, 35 spline axles.

Sounded like a well matched setup, and REAL axles! Can’t count how many times I’ve heard 9”, and “Heavy Duty” (do whaaaat?!?) 44 is getting it done..
