You to buddy. Some people compare dyno sheets and some guys RACE.

John, i think you missed a point. To meet both goals, pumpgas and season long reliability in a bigblock, it can be done, but will push stock blocks hard to achieve it. I want to hear Dragula won a season championship in shat air, run 5.900 in doing so and only had to change oil and check lash for the next season. That takes a pretty conservative, large motor to do. So that is my thoughts on how to get there based on experiance. The low stress is key, and allows money to be spent on a good base, like an aluminum block. With a combo like that, a data base for racing can get real long and accurate, unlike my last fifteen years of chasing ets.

The only base info with regard to a TF270 going 5.90's was HP given from a dyno. I wouldn't trust (spend money) based on that. Unless you are trying to be the first at something. That 470 Could have run 6.20's then what? You'd be stuck (spending more money).

Has anyone gone 5.90's with the 325EZ? Again just curious.

This car has EZ heads on it. Last year he ran a stock block 505 with TF270 heads on it. The 505 made about 750 hp with the TF270 heads, makes even more with the EZ heads although now he has a 572 inch shortblock under the EZ heads.

The TF270 vs EZ295 vs EZ325, on a 800hp type 540+ short block would be a fun dyno shoot out.
Then finish it off with some 440-1 cnc345’s.

It would be a very good dyno shootout. Just need $30,000 and a year or so to round up the parts!

I'm pretty sure I know how things would stack up but there is typically a surprise in the pile. Big question would be the cam. You can stack the deck either way by optimizing the cam for one end or the other. Probably get the best reaction from the crowd by using a big cam that was designed for the -1 heads. Then you get a big bang at the end of the shootout.

540 with 13.5 compression and a ported intake with a 1250 carb should make 750+ with the 270 heads and end up around 850 with the -1 heads.

What did it et with the 505?

9.70 to 9.90 depending on conditions

Let's not forget my friends car that I sponsored and wrenched on for years. It has gone 5.87 at about 117mph with a set of eddy rpm's that are pretty much maxed out. Hughes flat tappet cam, tunnel ram 2 750 holleys. About 2850#. 499RB. If I knew how to post a pic, I would.

Where do a set of maxed out B-1 heads fit in this line up?

North of the 440-1 heads

This is Andy F's old 514 with Indy EZ heads and a hand ported Victor Intake it went a best of 9.64 @ 138, 1.33 60' @ 3800 lbs with me 210lbs on a 9" slick

Nice picture. You have that car hooking up and going! Nice level wheelie too. Doesn't get much better than that.

Imo, “Maxed out” B-1’s wouldn’t even be part of the conversation unless one was shooting for, and building something capable of over 900hp.

Super Victor intake with a Dominator, or Victor?

This engine makes good power for Indy EZ heads. I'm sure there's more in it based on the mph/weight/ET not lining up. Probably a solid 850HP. Nice car/combo!

Looks good!!

Looks that way. That 514 usually made between 850 and 900 hp on the dyno when we were using it for part testing but in those days it had a dry sump system as well as a Wilson ported intake so it isn't the same combo that we ran: https://www.motortrend.com/how-to/modify-carburetor-run-oxygenated-race-gas/

Do you have a rear anti-roll bar in that car? The lift looks very square with the front of the car nice and flat rather than torqued over.

Sorry for Late response.... No anti roll bar ... Looking into it, I have 4.30 gears and crossing the stripe at 7500 + so I may change back to my 3.90 gears also got some Menscer Rear shocks.
I'm more worried about Diesel prices than race gas
