I have never heard/seen that site before, but just stumbled across it. Pretty neat BBF build.

Re: OnAllCylinders BBF 598 Build
here's an earlier one they did with a 520 (and a 347 and a 393)

Re: OnAllCylinders BBF 598 Build
The new build has a lot bigger cam (and more cubes), what's everyone's estimate on horsepower and torque the 598" engine will make?windsor wrote:here's an earlier one they did with a 520 (and a 347 and a 393)

Lem, is this the head package with the thin valve stems?

Re: OnAllCylinders BBF 598 Build
Really not impressed with this build too much, 750 with the old heads and 805 with the new. Used an off the shelf crane cam, meh.....windsor wrote:here's an earlier one they did with a 520 (and a 347 and a 393)

Re: OnAllCylinders BBF 598 Build
They say 360 cc & 2.400" intake valve...I'd have to assume 5/16" intake stem unless something has changed .68formalGT wrote:The new build has a lot bigger cam (and more cubes), what's everyone's estimate on horsepower and torque the 598" engine will make?windsor wrote:here's an earlier one they did with a 520 (and a 347 and a 393)

Re: OnAllCylinders BBF 598 Build
Not sure which came first...chicken and egg deal..... blog or magazine?
These "blogs" are the same articles written up in the IHRA's Drag Review magazine (IHRA equivalent to NHRA's National Dragster)
They have the write up as this engine will be on this year's prize car. IHRA Summit Super Series World Champ for this year will win a turn key dragster with this engine as part of their prize package. Past years have always been a generic BBC dragster. Glad to see a little love in our direction.

Part 3, with the dyno test: http://www.onallcylinders.com/2013/09/27/big-ford-horsepower-part-3-dyno-results-for-trick-flow-specialties-598-ford/
Made 1025. Not too shabby!

Re: OnAllCylinders BBF 598 Build
I'm calling bullshit on this one. Don't sprint cars run without balancers?ATI also says the damper can free up to 12 extra horsepower thanks to more stable valvetrain timing and reduced harmonics.
I'm not saying don't run one, but I don't believe it is 12 more than a stock balancer.

Re: OnAllCylinders BBF 598 Build
Just wondering .......why is the power level where it's at? Surprised there are no critiques from the forum.
My similar built 598 also is a pretty much an "off the shelf build" but made about 50 more hp and 84 ft lbs more more torque. (1069 and 920) I'm think I'm over 1100 now as one track tuning has picked the car up 4 mph (in a 2950 lb car) vs the dyno tune.
I did notice this engine has a bigger cam than mine with lot's more lift and a bigger intake valve. Wonder if the cam is too big and puts the engine out of the sweet spot on head flow.
Just wondering....thoughts?

Re: OnAllCylinders BBF 598 Build
Did they say what the duration & LSA of the cam was?
Never mind...I see part 1 now.

The piston domes are 5.7cc smaller than the pistons I did for you. Looks like you have a compression ratio advantage.
According to the flow sheet Charlie faxed me in aug. 2010 your heads are a little better even with the smaller 2.350" valve. Smaller valve + more flow = better performance i.m.o.
Once the lift for a given head is at or very near the 'sweet spot' range lifting the valve another .040" aint gonna do much, one way or the other, besides work the valve spring harder. Also, having those .080" wall p. rods behind the big azz triple springs the net lift may not be as much as one would think.
You ring package is .043"-1/16"-3/16". The engine in question has .043-.043-3mm.....so it should have a nominal hp advantage.
Re: OnAllCylinders BBF 598 Build
Sounds good too me. My machinist figured my compression out to 13.99:1 Didn't think this one would be any lower. Thanks for the info.
I had a sense that my 7/16 .135 wall pushrods were of some help but not sure how much. I knew the slight diff in head flow would help, just didn't think it would be that much.
For those who haven't seen it:
my head flow and dyno sheet for a very similar build to the article:
In the graph the hp flat lined but didn't fall from 6400 on up. Took a while but I figured it out on track. It was very rich. Just putting too much alky through it to burn any more. Ended up with smaller nozzles, way different return pill and a much different high speed bypass setup. Ended by with a smaller nozzle and smaller return bypass to use with use less fuel at a higher pressure with the high speed pressure upped by with a larger pill to keep the nozzles in a sweet spot most of the run. Still a touch fat on the leave and the shift, but afr looks good the rest of the time.

Seems that it matters a lot which 'shelf' the parts come off of

Re: OnAllCylinders BBF 598 Build
So true. By off the shelf I meant mine is not built from
One-off parts.
Just good stuff chosen by you and others. Parts that work well chosen by people that know.

Dave what brand push rod are you using, can I switch from 3/8 to 7/16 without any trouble, I was told I was getting about 22 thou. flex in my rods.David Cole wrote:Sounds good too me. My machinist figured my compression out to 13.99:1 Didn't think this one would be any lower. Thanks for the info.

Re: OnAllCylinders BBF 598 Build
Comp Cams 7/16. .135 wall
Only had to get some some 7/16 sized guide plates from Trick Flow.
Depending on your heads you might have to open up the pushrod holes in the heads. Slot them oval shaped up and down. My TFS 18 bolt A460 heads already had the slotting done.

TFS-54400624 7/16" plates
Even Fabio has 7/16" pushrods
Phillip has some 7/16" .165" wall that I got him from Trend products. I'm reasonably sure comp's stuff is produced by Trend...just more money with the comp part #.

Re: OnAllCylinders BBF 598 Build
I got blue thunder heads, maybe I will just go with the 3/8, 135 wall, I am using 1.80 rockers, to get a little more lift, and less flex on push rods should help a little, right?David Cole wrote:Comp Cams 7/16. .135 wall

Re: OnAllCylinders BBF 598 Build
They are not in the league with the 7/16 stuff but, the 3/8 x .135" are a big help.....especially since the cj style heads do not have the the extra lenght of P51, A460 or C460 heads.342g wrote:Thanks Lem.Lem Evans wrote:TFS-54400624 7/16" plates

When the spring pressures go up and the p. rod lenghts increase the demands on the pushrods increase also.
