Yeah, just mark it and relieve it with a mill or file or grinder. No big deal. S/F....Ken M

The Mancini rockers are Harland Sharp bodies without the roller bearings, I've heard nothing but good things about them. They seem the best value for dollar, and you don't need a lot for a flat tappet, but the stock rockers aren't adequate. If you can find the Erson/Crane/Mopar ductile iron...

That much lift on what's probably an aggressive cam is going to murder those rocker arms. Spring pressures? There will be a lot of flex, and a pushrod will eventually poke through the rocker arm. S/F....Ken M

Sleeve it. S/F....Ken M

Did they talk about turning it into a B-spec crank? Mains to 2.625 and rods to 2.200. If you're just going to use it for a doorstop, and it's a factory 3.75 forged crank, I'd be willing to buy it and see if I can repurpose it to a low deck. S/F....Ken M

The Icon piston is a better choice, if you want to swing the $200'ish difference in price just for the better 1/16" ring package. In a perfect world I'd prefer if it had a .990 pin, but that piston was designed by a guy on moparts for class racing, and they use stock rods, no bushings, from...

Icon 687 is the best choice, agree with above. S/F....Ken M

Even if it's used up past 440 dimensions, it can be ground for a low deck and BBC rods and serve a long time further. S/F....Ken M

B1's are wedge heads, the Predators are a canted valve setup and some classes don't allow/penalize them. There really isn't anything comparable from Indy, maybe the 600-13's, but I have no experience with those. The B1 Originals are commonly ported to over 400cfm, the moved centerline heads...

That seems like it's down a cylinder, what do the plugs look like? Were there air/fuel ratios recorded? I did a 406" B block with mildly rubbed on 452 heads that flowed 245cfm@.5, 8.2:1 compression, Erson 230 something hydraulic roller, with an out of the box Holley 750 vacuum secondary on a...

I'm posting this as another option, and some data: I built a 400 using the stock crank, albeit forged, and had the rod journals ground to 2.200 (BBC) used 6.800 rods with the Icon IC828 piston with a compression height of 1.485. The block was decked to 9.965, so the pistons were .010 proud...

We just put 8 sleeves in a megablock because it wouldn't go 4.500. If you know everything else is good, sleeve away. S/F....Ken M

You guys are creating stress risers in aluminum parts for nothing. And MIGing on heat treated wrist pins.....FFS. S/F....Ken M

If you want nice mopar heads that legitimately flow 400cfm plus, you need to be looking at B-1's, not Indy stuff, at least not anything less than 600's or Predator stuff. S/F....Ken M

Sleeves are stronger than the block material. When you sleeve, it's part of a complete rebuild, you re-hone every hole to spec, unless it's some desperate "I need this cause I ain't got no money" 3rd world nonsense. It's so much cheaper to do it right the first time, instead of blowing...
