2018年3月3日 · I've always felt that 427 SBC's could be made to be torque monsters. Cubes, with small port cylinder heads that flow like crazy is a recipe for torque. 1971 Chevelle SS454, T56 Magnum 6 speed, 3.31 Posi

2010年7月21日 · The combo that I've selected for my 427 SBC is (drum roll....): Custom billet solid roller: 252/256 duration. .594/.594 lift. 109 spread. (This is the cam that Shafiroff runs in their 595HP 434SBC). AFR 210cc full CNC competition heads. They flow 308cfm at .600 lift. Super Victor intake. Custom carb by Pro-Systems. 1 3/4 Hooker Super Comp headers.

2004年8月7日 · I just had a 2-bolt 400 sbc bored .30 over and had it all checked over...Now my question is i have been seeing these 4 inch cranks for the 400 sbc that makes it a 427 sbc...is there any advantage of this new crank or would it be less reliable and just end up being a big turd.

2013年10月19日 · My 427 sbc has flat tops and 75cc heads (AFR 210s) and is around 10.7 CR. My combo uses the Eagle crank/rods. My builder did quite a bit of prep and massage on both and I think it went beyond what I could've done in my garage, but I let them pick the parts.

2014年9月2日 · Looking to build up a 427 SBC for my Vette. I want to switch to the ls firing order and am thinking of just having the specs of a LS-7 stage 2 hot cam or similar custom ground for it. Ohio Crankshaft ,Tri-Star Engines,White Performance and Machine , and RCG CNC BLOCKS INC.all have Dart based short blocks in a similar price range.

2019年10月25日 · That small a cam will be pretty mild in a 427 SBC, so it sounds like this is a driver?? 195 to 210 cc head range sounds about right for that. Iron heads, on a big bore block like that, with that small a cam is going to have detonation problems with 10:1 compression.

2010年2月5日 · in most all peoples opinions the 3.875 crank is the biggest stroke that can be ran in the stock gm 400 block, if i were to run a 4.000 stroke crank i would get an aftermarket block. the other thing i'm saying is that a 4.000 stroke with a over .030 bore ie; 4.155 is a 434 cubic inch motor, but a 3.875 stroke with a over .060 bore ie; 4.185 is a 427 cubic inch motor, but it is pointless to bore ...
