I did not know that. Interesting.

Belvedere was back at the track today making passes. First pass he hooked up and the car went way up into the air. Scared the driver a bit since the car had never gone that high. Front was probably 4 or 5 feet in the air. Next pass he lowered the two step too much and the car bogged off the line. So it is a work in progress.

Only made two passes?

They were still racing when I left. Even with the bog off the line he ran a 9.30 so once he gets the launch sorted out he should pick up some.

Looks like the car would benefit from an anti roll bar.

Yeah they were talking about that. I think they are going to put wheelie bars on it and add a rear anti-roll bar.

Definitely NEEDS an anti roll. Lots of ways t tune a wheelie out and if only using them as a "safety" device will be just bad as tuning the wheelie out on performance.

Ran a 9.27 today without any changes to the engine.

Getting there Andy. 794 hp what was the best mph?

145 mph. Wallace says 850 hp, Moroso slide rule says 810 hp. I don't think the calculators are correct yet since the car isn't dialed in. The driver is still working on the best launch RPM as well as shift points. The chassis hasn't been fully sorted out either.

I thought the race weight was in the 3200lb range??

I posted that the car weighs 3000 lbs

So, 3000+ driver.

I guesstimated 3200........ I suppose that could also be 3300, or more.

Yep, driver is a very big guy.

The Big EZ heads made it two seasons before they developed leaks in multiple intake ports. So we're looking at different options. Looks like the best bet is to step up to a set of 440-1 castings with the 345cc porting package. We'll have the heads cut to the same 74 cc combustion chamber so the CR stays the same. Hopefully valve to piston stays the same but that will need to be checked. Hopefully the valves, springs, rocker arms, etc. all swap over from the Big EZ heads to the -1 heads. As far as I can tell everything will swap over, but I could be overlooking something.

I was of the assumption that the intake port of the EZ was the same as the -1. The difference between the two being the exhaust port height. I have to say I wouldn't be happy with multiple intake port leaks after 2 years of use.

Oooof! that's not right. Hope there is some restitution for you. Do they leak OIL or COOLANT? What MPH/ET did the car wind-up running? Probably not great MPH because it's not the most aerodynamic set-up.

The cnc345 is really better with a 2.25” intake valve.

Were those used in the EZ heads?

As cast, the EZ head has its own unique port shapes not shared with the other models. The floor is higher than a -1, with a much more rounded approach to the SSR, and a larger SSR radius.

I do believe the ez325 and the -1 325 utilize the same cnc program in the intake ports(I’m not certain of this since I haven’t had a pair of each here in the shop at the same time), which removes quite a bit of material from the EZ floor.

Agreed...the -1 345 SHOULD have the 2.25" And IIRC AndyF said his had the 2.25 installed by BEST. Wonder if they use the 'SR' INTAKE port with a lower exhaust? Randy has the cnc '345' -1 Indys with 2.25" Intakes on his jalopy with a SMALL/gentle cam you spec'd. 540" 12.9:1 It showed about 146 or so MPH so far @ 3300lbs. But there's definitely room for more in it's performance.
