woah...check out this pump gas 383

Guy's I would not testify to accuracy on a dyno, because I have seen the results working for Cummins Engine Company, but I will speak for Tony's character. He is by no means a average joe engine builder. The engine on page 2 of his web site is a very good friend of mine and Tony has done everything for him over the last 2 years. Two guys who run his engines or engine combinations and machine work are Dale Perry and Brandon Fugler who I know personally. They have had nothing but positive things to say about his work. They both have outlaw cars full body with ladder bar set up running 5.11 to 5.14 eight mile times.They have been very competitive running in Texas, Tenn., and Ms.

Tony's personality is not one of blowing smoke but is conservative when giving his recomendations.

Port VS nonPorted all depends on engine volumetric efficiency. Tony has been around for years DOWN HERE IN MISSISSIPPI. Not ranting , just a little person info .

You guys need to remember there are two ways to make more power at the flywheel. 1) create more HP to begin with or 2) reduce parasitic losses internally. I suspect he has taken some steps to reduce parasitic losses.

Novaguy73 · Nov 23, 2006

Yeah this is kind of what i thought id see. Ok so lets say he dosent use any "tricks" No low tension rings, no loose bearings. Just some typical off the shelf parts for this buildup. Same cam, IK 200cc heads and off the shelf headers. Would we be talking about a 40-50hp difference? I suppose this motor would still be over 500hp and 500ft lbs, wouldnt it?

Tokyo Torquer · Nov 23, 2006

Gee, he makes somewhat near the same hp and torque as me at the same peak hp rpm, and I needed double digit boost to do it. Maybe its my "crappy" AFR heads holding me back. I never trust dyno numbers.

His own 468 BBC motor doesnt even make a whole lot more power at 603hp/614lbs TQ.

I cant say for certain, i dont know specifically what he did, just what i would think that he did to find more HP.

Straight-line-69 · Nov 23, 2006

I still say BS. Tricks or not, 1.5 HP per CID on a naturally aspirated SB-383 (and SB heads) that peaks at 6000 RPM, ain't happening.

No way! 568 HP at 6000 RPM on a 383, with 200cc heads, and a fairly moderate cam? Please.

Also, the dyno numbers don't work. HP and torque will always intersect at 5250 RPM. The numbers reported don't work.

I call BS.

What i said.. FULL OF CRAP!!

ive ran a 355 in a 2950 pd car that runs 10.80-10.90s at over 8000ft density alt. so do the math, thats an easy 450 or so hp motor. now at sea level thats another 80-100 hp.still with a 3.48 stroke i think its believable. ive seen 355 stock eliminator motors in ihra top stock class with unported gm fast burn heads and hyd rollers runnning hi nines in a 3100 pd car so it can and has been done i think too many people around here claim bulls--it when they see something that they themselves cannot do .as for shermans motor, with pro action heads(rhs)they flow 10 cfm better out of the box than a stock vortec. ADD THE 10-15 CFM MORE HE SAID HE ACHEIVED BY PORTING AND YOU ONLY HAVE A 250-260 CFM HEAD WHICH THE IK2OO BRODIX FLOW OUT OF THE BOX so whats the issue. same head flow and more cam ,with better ring package, and who know what else. why so unbeleivable?

67RS502 · Nov 25, 2006

Dont think anyone is callin bull on Shermans motor since it ran 130mph we know its makin the power. But the other guys makin 570hp at 6000? I think you'd have to spin it higher then that. Like I said before it can be done and then some, but there seam to be some things that look a bit fishy with this one.

camaroman7d · Nov 25, 2006

NER Performance, Was your above mentioned 355 running pump gas? What kind of compression? Heads?

NER perf · Nov 25, 2006

11.8 to 1 comp with pump 93

NER perf · Nov 27, 2006

ive been checkin this motor out closer and ...............
i think it could be even more for real seeing as though alt is higher in la where sherman dynos his motors. also a larger runner head will work better on a larger motor, not only due to peak flow, but also runner cross section .you need to put some port size eventually into a bigger motor .velocity only goes so far:waving:

67RS502 · Nov 27, 2006

The thing with a bigger head is - this guy is makin 570 hp at 6000rpm?
It would be more believable if it was at 6500-7000rpm.

NER perf · Nov 27, 2006

yeah well i guess unless were in the dyne cell well never really know the truth huh:thumbsup:

...and where's the red-line on these small blocks? That's the issue here. We'd all agree SB can make 600 HP and more naturally aspirated. But they don't peak at 6000 RPM.

NER perf · Nov 28, 2006

im trying to give this person the benefit of the doubt.

i have no vested interest in this ,just dont like callin someone a liar ive never met is all :clonk:

Guys- I, too, questioned the Barker engine when we did a quick column on it in the January HOT ROD. The lb-ft and hp does cross at 5252 in the dyno curve I've got, so not sure what that comment is about. The heads had CNC chambers, bowls, and port-match. The pistons are Mahle with 1.5/1.5/3mm rings, and all the bearings are coated. The cam lobe numbers are Comp 3317 and 3318 on a 112 LDA with 1.6 rockers on the intake. Don't overlook the 1-inch spacer and the sprint-car-style step headers.

I guess I should have coated my bearings and ran a 1" intake spacer instead of bolting on 14 pounds of boost to achieve only marginally higher peak power at a similar rpm in my SBC. That is a lot of power for that size motor and rpm. Volumetric efficiency must be extraordinary.

I not sure what discussing dyno numbers really means anymore besides empty bragging rights to impress others less knowledgable. Instead of trying to figure out the smoke and mirrors behind the numbers, we need to put it in a car with a known weight and good traction and see what the drag strip says.

Freiburger · Jan 3, 2007

Not disagreeing, just informing.

Tokyo Torquer · Jan 3, 2007

I know..sorry, didnt mean to sound like a smart a$$.

If this was a one off engine with lots of special work, I might beleive there was some magic, but this is a mass produced crate engine (with quality off the shelf parts) he is advertising and shipping out the door for $7995.00.

woah...check out this pump gas 383
