Go to Wallace Racing. They have some pretty good calculators on there and you may already know of them. At 96 mph and 3448 lbs, the calculator is showing 474 flywheel horsepower.
@@patrickmoore1017 That's what is out of place. We watched the engine make 588 horsepower and 505 torque. There is a video of that session on here. Something seems to be off.
@@406MenaceRacecar He tried to make an engine that my son can drive ten miles to a cruise in, Sonic, etc. but can do pretty good at the strip. We could have went more compression and made more power. Car drives great on the street and doesn't let us down at the strip. We wanted a best of both worlds if that was even possible. I think the car will go 6.60's weighing 3400-3500 pounds with driver. Maybe the degree that the cam is installed on hurt the torque?? Don't know.
We had an engine dynoed on a Stuska PowerPro dyno by DynoTune Engineering in Paris, TN in February. It's very similar to your engine. Factory block, a 330817, 11.7:1 compression, 4.165 x 3.75 bore and stroke, AFR 220 heads with 2.10/1.60 valves, a 263/264 at .050 cam with around .700/.650 lift and on a 107.5 LSA, a ported Edelbrock 2892, a 1000 cfm carb, VP 113 fuel, a vacuum pump with -13" of vacuum, and the same headers that you have. It made 614.5 hp at 6700 plus 542.9 ft-lbs of torque at 5500. I have a street 72 Nova that weighs 3300 with me in it that we're gonna put in it with a 5500 converter, a Turbo 350, and 4.10 gears in a 12 bolt that we're looking to go 6.50's at 105 mph in.
Patrick, thank you for sharing. Very similarly built engines. I think we should be going quicker and the mph seems a little low. When are you going to the track?
@@jeffreyburress2200 It will be in the spring, and I'll let you know how it turns out for sure. I have daddy's 68 Nova going right now testing and tuning it every once in a while. It's a 434 sbc with stock Brodix Dragonslayer heads on it, a similar cam as the one in our 408, 12.5:1 compression, a ported Edelbrock 2970 Super Victor, a 1050 Dominator carb, and Hooker 1 7/8 headers for a Nova on it. The car weighs 3050 lbs with me in it and 5 gallons of fuel, has a Powerglide with a 5500 converter, 4.10 gears and 28x9 Hoosier slicks on it. Last time we went to the dragstrip was 30 September in 700 foot air, where it ran four 6.14's at 111 mph, with a 1.35 sixty foot. This was at Jackson Dragway in Jackson, TN. I'm not bragging one bit my friend, it's just fun comparing combinations. I know I walk the pits all the time looking at engines and asking questions so that I might pick up tips on how to make our ol cars run faster. Our cars are nowhere near as nice as y'alls GTO! That's one good looking car!
@@jeffreyburress2200 yeah I have a couple, but I don’t know how to get them to you, other than Facebook. Cam card calls for .020” and .022” for lash, but we run them .006” tighter on both lobes to allow for expansion of the aluminum heads.
Cool beans bubba that’s pretty good.i have a couple 406’s and I’m always paying attention to dyno pulls here so I can have an idea about mine but we’re looking for different power.i’m only looking for 500 in a daily toy but you’ve got some awesome stuff there,good luck with it
Don't mean to burst your bubble, but that engine will probably not make more TQ and HP under different weather conditions on the dyno, because that's what correction factors are for. All those values shown were "corrected" values and compensated for temperature, atmospheric pressure and humidity. If the dyno is calibrated correctly, the corrected value should always be the same independent of weather conditions. Chances are the dyno is not perfectly calibrated anyway when it comes to atmospherics and inertia factor, because most dyno owners/operators either don't know enough about it or don't care enough to do it right and therefore more dynos than not show more TQ than the engine is actually delivering. It's actually beneficial for their business, because mostly they are also engine builders and it supports their "good work" when the dyno provides happy numbers.
I believe a lunati voo doo on about a 282 seat to seat maybe even as much as 288 would work better considering the head flow,the engine should run to a higher RPM. It just seems like this engine can handle quite a bit more
Correct, it can absolutely handle more. With some minor adjustments it is capable of well over 700 hp. We'll shift around 7400 rpm at the track, but will maily use for cruising. Thanks for watching and commenting.
Reed, you are right. Those heads can breathe. The engine builder was told to assemble an engine that would see more cruise-ins than drag races. The car will be raced quite a bit but street manners was important. Kind of a 'best of both worlds' engine.
@@jeffreyburress2200 Congrats no better day than a good day at the dyno, excellent hp and tq #'s especially under those condition's. The #1 goal for my Sonoma engine was the ability to drive it on the street with pump gas.

Come to find the spring pressure is to light and will be upping spring pressure to get the revs up to 7000+, Not that i'm putting it back on the dyno but I feel confident there might be a nice little amount of power in those last 600 rpm especially as the heads are only getting more efficient with the higher rpm. If the hp rise remains linier it should make 675-680, it's going to be a nasty street ride. Nothing better than a n/a engine in my opinion.
@@jeffreyburress2200 I do plan on getting it to the strip, it's in my 94 Sonoma/turbo 400, 9 inch/3.55, complete Caltracs. A friend of mine built it for himself and grew tired of the project so I bought it from him. At 63 this is my retirement street toy. lol.
That was a fantastic day! Danny Sr. came through again. Terrible humidity and temperature but still strong numbers. Danny is an engine master.
Was definitely a blast! Glad a couple friends were able to go with us too!

Seems you would have made more torque don't you agree? Especially being a 400 block

Yes

What kind of compression are you at?
11.9 to 1
