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.

I think you are reading a little too much into my response. I never took anything there...did not need to. It's all in the past so if you are happy that is the important factor.

Most folks know the HP formula:

HP = TQxRPM/5252

Once the rpm reaches 5252 then HP=TQ

I was off on the compression , it’s 10:1

Very nice, I like it. Who built the headers,if you don't mind me asking.

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.

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 have never seen an air temp stick at the exact same temp through a run when the meter will show you down to the .1 degrees, mabey the temp sensor was away from the engine and a bunch of dry ice was packed around the intake, mabey the dyno calibration is a little off... no 358 is gonna do that power that low in the RPM range, I would say they need MINIMUM of another 60 cubes. Mabey the listed bore and stroke are not what is really in it

The math on the HP TQ and RPM are correct on the sheet but the dot is in the wrong place

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

Guess you need to put it in a car and post the results.

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

There is hidden cubes, nitrous or dyno calibrations causeing those numbers.

Yeah that challenge thing is interesting, bigger motor less HP and TQ

I am also wondering why they quit pulling at 5000 when TQ and HP where still climing?
