No way that a cam change, with a little head work, and a carb/intake will gain you 260hp, even if you started with the top dog 240hp.
You are only showing just how much you don't know about a bbc engine. And or have used a bad combonation of parts all along. ha ha!

Really?? I wuz thinking 275 or so.I don't think that engine,built as he descibed will dyno @ 400 if it even survives the dyno pull.I also don't think any of the heads listed will support the RPMs he is supposedly making his #'s with.I'm no Engine Guru'but'I gotta call BS on this one without some sorta proof.

Protested? What would they protest you for? What class do you run your car?
I don't know of any track that allows protests for compression ratio?

I'm right there with you joker! I've had BBC's and had them dyno checked too. Also built many like my present engine that use pretty stock bottom ends, and held together well if I shifted under 5500 rpm's.
The .040 over 454 in my '63 Falcon is a mid 70's with 8.5 cr, and the small chamber edelbrock heads boost it to around 9.25 cr. I wish it was 500hp, and I think I might be getting over 400hp easily, but doubt it's much more than 450hp.

Oops! That's $2100. Still not 3-4 times the $1,000 you say you can build one for.
And I bet I'm closer to 500hp than your build is. Where do you live? Let's go racing!
At least you know how to spend your money for good used parts. You better have some serious rear gears for that over carbed over or under camed big block And if you are talking you're closer to 500 hp than I am you should be closed to 650 hp with that tunnel ram and two fours on top. Thats what that intake carb is for with some at least 515 rear gears in a Ford nine in rear end. L@@ks good with that weiand tunnel ram and twin 600 cfm or 660 cfm Holleys. I'll bet that your engine is cold blooded until it worms up a bit with that tunnel ram

If your cam is big enough then your right there at 500 hp. the performer 2 0 simi closed edelbrock heads have enough to flow to support over 540 horsepower out of the box.

Well at least you got one thing right. Tunnel rammed engines are all a little cold blooded at first firing, but since I run a mechanical choke, that's not a problem. It only takes 5-6 minutes of driving to get warm enough.
I'd also guess you've done very little work with a BBC, or you'd never suggest 515 gears in the rear. A BBC with 515 gears would be around 5200 rpm at 80 mph. You'd have a tough time even finishing the 1/8 mile without winding too high, let alone do any 1/4 mile work! A BBC with it's great torque characteristics doesn't need gears anywhere near that low even for 1/8 mile drag racing.
And a tunnel ram can work extremely well at low rpm's and doesn't need to be wound up to the 6,000 rpm range to give plenty of low end grunt and power. I'm running 3.73 gears in my 8.8" Ford rear, and can easily break the slicks loose at most any speed/rpm in 1st or 2nd gear on my Super T10 4 speed.
You really should look at the build that Horsepower TV did on a 454 Chevy. They completely rebuilt it, plus swapped cams, and installed a hi rise intake and carb, with headers. They did a nice build and dyno'd it at 409 HP. Nowhere near 500hp.

Make up my mind? First you say my engine is 650 hp, then it's 500 hp. I still think you're guessing, just like you are with your build.
I built my first BBC in 1973, and I've lost track of how many since then. I've got a pretty good fell for what it takes to get to 500hp.

It's not for compression hell you can run as much as you muster. But they are build limits on the engines. No more than a 0.60 over bore, stock stroke, no roller camshafts, no nitrous. No dry sump oil system. Only a windage tray with trap doors are allowed no lengthening the oil pan or knife edging the crankshaft. Car must weigh no less than 3200 lbs. slapper bars and ladder bars are allowed, wheelie bars are allowed. No back halfing cars allowed. drive shaft holder a must have. Any lines have to be steel braided no more than 10'' slicks allowed. scatter shield or diaper is mandatory for automatic trans cars driveshaft hoop mandatory. steel braided lines for carb brakes. most all cars are running 500 and over horsepower. Soo... there is a lot to protest, when you win too many races all the time. If they find nothing wrong they have to pay the money they protested with for a total rebuild either by a machine or for yourself to build. I do not allow anybody to work on my engine. So there you have it

What track and what class are you running with these rules?
Hope you're talking Little River Dragway, as I have a good friend who runs there, and you can pass your time slip along to him.

What class & @ what track are you running @?Nobody is tryna call you out.It's just that there is a wealth of experience here & you are making some really extreme claims here w/o anything to back any of it up.If you can & do these things,more power to ya.You are the Man.But,excuse us if we need some type of assurance in order to believe what you say.As heavily as you would have us believe you are into engine building & racing,it should very simple to back up some of these claims.Video,time slips,dyno slips,etc.Something ???

515 gear is only a reference of gears for the eight mile with a 6500 rpm limit with 28" rear tire. So.. you went the the torque route with you tunnel ram. I've seen over 8000 rpm on a 427 bbc and a little less than a thousand hp. You come to little river with a chip on your shoulder or act like you knoe everything around my chevy drag racers and they will not even talk to you. We are not down with all that negitive talk. We are there to have fun and n ot get into a pissing contess on what is what. Theyd run all three you guys off with all that negitive energy

You started out with a stock 454, and now you're talking about winding it to 6500 rpm's? If you do much of that you'll be at the local wrecking yard looking for another stock 454 to build soon. And 515 is NOT a good reference for the 1/8 mile, unless you've got a well built SBC or BBC. We are talking stock bottom ends, so why reference a 515 gear?
No body is giving you attitude. You came here to brag about how much HP you get from a stock 454 bottom end and a little head work, but refuse continuously to show any proof of it. Then you decide to start telling us we're too old to learn anything new, when you've got no idea how long any of us has been doing this?
I seriously doubt if a good bunch of guys at any track would listen long to the claims you made here if it was done face to face. If they're good guys, they might be polite and just walk away, but they'd still wonder what you've been smoking.
Now are you at Little River Dragway, SC? Or where? And again, WHAT CLASS has those rules? What year Chevelle? I'd like to have a friend watch you run!
