edit: This should be good. Ever hear someone say "There goes another Nicker-bomb!" at the track? It used to be pretty common but things may have changed.
Does name calling make you feel manlier
It's not name calling...it's history. Tighten up man. That said it sounds like a cool motor, let's see some pictures of it. Did NVR machine/build the engine? 'Just curious...
Tighten up? Are you kidding me? You’re talking about a man’s business here. Did anyone ever tell you that you suck at your job? Ok then, give me facts about your rude comments and I don’t want to hear about my buddy told me, or I heard of a guy , or my mom/sister/aunt told me……………..GIVE ME REAL FACTS! Did Tom ever build you a race engine? I’d be glad to check you out in his archives. If you know Tom, he never throws out customers’ information so I’m sure I could check your file. Let’s see what you got ……PM your real name and I’ll check you out……… yes Tom did all the machining and building……… What do you currently race, please show us all.
Funny thing is what “CAB” said, all engines should show the same HP and torque at 5250rpm. The funny thing is Tom taught me the same thing years ago. I thought it was amazing that my 505 and my buddies 340 both had the torque and hp meet at 5250. Should I also post the last couple engines he did for us? Would that make people feel better. So I may have the torque numbers off a little, I was excited and never wrote them down, As I stated, I’ll post the numbers this week.

Most folks know the HP formula:
HP = TQxRPM/5252
Once the rpm reaches 5252 then HP=TQ

I'm just a hack, but I'm calling shenanigans. something is off.
if it really is 354cid, 1.77lb-ft/cid for a naturally aspirated street motor is not possible. the best I've seen is about 1.4-1.5 was this hot-heads's dyno, or a 3rd party dyno operation? if it had a 6-71 pushing out 6-7psi I'd believe it...

so...about the same as some IMM prepped RHS magnum heads, maybe a tad better that OOTB W2's....fully ported, what, maybe 300-320cfm max? no, I'm not buying it...I could see that torque number, maybe, out of 470-490 CID with 10:1....

Could the dyno calibration be off. I'm no expert, but i've never seen numbers like that for an engine that size and at such a lo rpm. ![](/ubbthreads/images/graemlins/shruggy.gif)

I would consider it a 2nd party dyno (done at NVR). Hot Heads spec’d their heads, intake, and cam combination and NVR did the rest.

I’m perplexed about the comments. They build 355 Chevy circle track motors with 700+hp frequently. Those motors are only 9.5:1…………. And NVR isn’t to only guy in town doing it. Circle track racers jump around to different builders all the time. No one ever talks about dynos being hot, fat, off, whatever the lingo is. You guys are funny
Compression isn't the issue to me, I am cool with it (makes it a little harder but still do able, even if it was 8 to 1)but it is just the low RPM range they are doing it in and the TQ numbers for that size of engine, ask you circle track motor guys how many of their 355s are makeing 630 lbs TQ any where in the RPM range ![](/ubbthreads/images/graemlins/thumbs.gif)
There is hidden cubes, nitrous or dyno calibrations causeing those numbers.
I am not causing global warming, I am just trying to hold off a impending Ice Age!
