Update- decided to go with THE block (which I have received),at 4.500" bore and 3.915" stroke to net 499". Machine work is being done and engine built by Best Machine, as I'm sure Chuck and Pete will make way more power than I could. Will be using a motor plate to fit a dry sump pump. Still shooting for 950hp+ NA. As of now, I'm inside of a year to have the car built...should be a piece of cake! I would think they would make more like over a 1000 HP easy Jerry. You will be turning it up in the RPM range, like 9000+ though I would think.

That's 25" smaller than my M/C deal was that ultimately got well over 1050hp. Don't see 950 being to difficult as mine was far from a max effort deal. Went 171 in a 2975lb car so you can do your own math.

The Bonneville Salt Flats is, IIRC, 4200 feet elevation. That's an automatic 15% derate in horsepower. Oh, rats, I see you've already covered the Density Altitude of 7700 feet. 5280 is -20% at standard temp and pressure, so the 7700 would be something like 33%?

I think more people need to come and experience what we get to experience out the west. A lot of things go into factoring a DA. I don't think they understand the barometer is 25 there...It has a way of kinda killing an NA car. I don't know the correction factor for RMR but it has to be .95XX given the altitude. Even NHRA slows indexes down .45 seconds there..

Rulebook says same material as original block, all OE parts must bolt up, etc. I'm going with close enough. Didn't want to build a time bomb 400 block. This block is approved for NHRA SS as I understand it, so I'm rollin' with that.

seconds there.. Last correction factor was 1.27 at 8150 ft corrected. The car is typically .3 slower from Las Vegas, and there is a whole bunch of variation there.

Well and we both know Vegas is at least .2 slower than most tracks. Poorly tuned combos will be even slower. But its a fun experience in all the thin air around here. I know we are celebrating if the barometer reached 28, its party time and we are gonna FLY!!!

So, the 499" Bonneville bullet based on a B "THE BLOCK" is almost finished at Best Machine Racing Engines. Unfortunately, I need to bring it home to FL, install and plumb the dry sump and have headers built prior to taking it back for the dyno session, so the numbers will still be a while. Hoping for 1000hp NA. It has been and continues to be a long road, but still planning to make Speed Week 2019!

These heads proved to work well for this 498" B-block endurance build. Made 947hp @7400rpm and 690tq@6800rpm on Best Machine's dyno.
KOS, not sure about spacers, I think the motor plate takes care of it. Best Machine could answer that.

KOS, I went with the Jesel timing belt drive and distributor based on Best Machine's recommendation. Timing belt due to cam and valvetrain harmonics, and the distributor to have a bigger cap to lessen likelihood of crossfiring. This engine will be WOT for up to two plus minutes at a time.
The Meziere water pump I chose because of flow rating and to free up some power. After going down this path, I spoke with Meziere and they said a mechanical pump would have been better...so time will tell. I did get a custom Saldana radiator for this project, so hopefully it will work.

Do you think you will make it out here this year? If so the early SCTA race or the later BNI race? How hard is it to get a room when the races are on? I'm still watching you on this I decided to not try and make the car I wanted to build after they both drop the all wheel drive classes

Yes, if Speed Week occurs I plan to be there. Still need a few bits and pieces (driveshaft, a pair of 28" Moroso DS-2s, and a fee other odds and ends), and have a ton of work to do, but I have most all the systems to get it together, just have to get it all installed. I am focussing on it to try and get it done this year, at least for the maiden run!
