This is from AFR's website.
I'd love to know what the cam specs were on these puppies. If you look at the hp and torque even at 2500 RPM, this is a killer combination. Anyone happen to know the full cam specs? 406ci SBC HP=550 Heads: AFR CNC Cyl Heads 210cc Race Ready Compression: 10.3:1 Carb: 750 cfm Ignition/Timing: MSD HEI Billet Distributor 36* Timing Cam: Lunati Hyd. Roller Cams 232*/ 242+ .560-.570 lift w/ 1.6 rockers Exhaust 1 3/4" Headers Fuel: 93 octane pump gas RPM Torque H.P. 2500 463 220 3000 468 267 3500 457 304 4000 465 354 4500 534 457 5000 540 514 5500 510 534 6000 483 551 AFR has another example with a solid flat tappet and 195 heads that makes even more power. (570). -- Joe |

I like the build that Mark Bychowske did with a 370 cubic inch LT1. I believe it was 476rwhp and 402rwtq. Looking at the dyno graph I think the horsepower was still rising at 6500rpm when it was shut off. Now if I can only duplicate that motor.

I know I'm pleased to death with my 383, high compression, 230/236 cammed, AFR 195 street ported head engine. I can only imagine what more cubes, more cam, and 195 comps would feel like. Wish I could afford a 434 with about a 252/260 cammed engine with AFR 235's on top.

Hi Joe, I have a friend here locally that is a bracket racer. He had some W.P sportsman heads that were ported. It is a 74 Nova 406 sbc 12.0 compression, 252/260 solid roller,Edelbrock Victor and a 850 carb. He was running 12.20@109 in our crappy DA (6000-9000ft). He swapped for some race ready AFR 210's on it (not the comp 210's) and now he runs 11.50's @116, just from a head swap.
After porting the W.P heads, the port volume was about the same. Get some AFR's, and you won't be disappointed! |

Sounds good. Yeah I'm planning on the 195 eliminators. Probably mill to 60cc chambers to get the compression up. I'd like a solid roller. I'm just a little weary about it because I've heard of a lot of failures at idle. I'd like to stay away from hydraulic though because of lifter pump up and bleed down. -- Joe |

Here is a link for a nice set-up.... he's accessible to talk to you as well.
Its a 418 sbc.... curve was still rising when they shut it off..... probably makes 570ish up at around 6000-6200 rpm, but not sure. Look at the torque curve.... extremely stout across the entire rpm range, especially for such a docile hyd roller cam. I think he got his heavy chevelle into the 10's with that set-up. http://www.chevelles.com/forums/showthread.php?t=218368 There is another guy with a 414 sbc, basically identical to the above set-up, but he's running E85..... made over 600 HP with basically the same hyd roller cam as above. Power was all in by early 6000 rpm. I can dig-up that torque curve somewhere if you're interested. |

But, did you do it in a 6000-9000 ft DA ? If that fella in the Nova drove off that mountain to a sea level track, it would run another 5 mph minimum and probably more like 8-10 mph faster. An 11.50 car at that elevation & DA is an easy 10 second car at sea level. Just food for thought. |

I've had issues over the years with Comp hydraulic roller lifters in OE roller blocks. However, my 400 isn't an OE roller so I need to run retrofit either way. -- Joe |
