SVO460- RE; weghts, your wrong on this one. The 427SO block was the heaviest standard production FE block due to its webbing. And it was still some 80 lbs lighter than the lightest late model 80's 460 block. A aluminum SVT 460 short deck block weighs exactly the same as my DIVE production block due to increased webbing in the SVT block. I know, I own both. A DOVE 2 or 4 bolt main iron block weighs about 20 more than a DIVE block with the lightest 460 block being a 90's truck block. ALL of the high deck iron and aluminum SVT 460 blocks are heavier than production stock iron blocks. The production heads and intakes of both FE's and 385's weigh about the same, all things being equal though. The Edelbrock listing I have shows their aluminum FE heads (2 each) are only 8 lbs lighter than a set of 460 heads. A 352/390/410/428 dependent on year are ALL lighter than a 427SO though,,,,,,,,,
BTW- I'm a sorta 385 type of guy. But no one in their right mind would fool with a 427SO Cobra or badmouth them. They are still very much competitive with anything out there. And that includes my blown 385. For me it's a cost factor, I don't want to take the chance of messing up expensive parts foolin' with hot rods. So it's a 385 for me. Then there's that damn Shelby block,,,,,,,,,,,,,,,,,,,
