Serious build there. What intake & carb(or EFI)? Any dyno numbers or power estimate?

Moving the Super Victor EFI intake over that I originally built for the 461, it's all setup and ready to go, just need to do some minor gasket matching. Holley Dominator ECU.

Previous pic of 461 pic attached with the intake being used.

Based on past history, Paul conservatively gestimated @665hp, @550+ ft lbs. As stated, the main holdback is the head flow.

I would expect a Moser built rear to last almost forever, how hard did you beat it?

Um. Hard. As much abuse as you can imagine with street tires. But it was like over 4+ engines. A lot of N2O, and think I replaced the ring and pinion once, can't quite recall.

With the 461, it was eating pass axle bearings every 50k miles or so. Housing is straight, it's just that I was pushing it hard. Think it might be the earlier style TruTrac too, which has been updated.

I will go through it, it's time. I can do it for about $1k-$1500 max. Will do u-joints too. It's probably just time.

I will dig out the receipt and check what's in it, and should get an exact date then.

So looked up the receipt for the rear build, it was in '01. It's time.

I bet it makes more power than that. My race motor is 500 ci with a similar size SR and 335 CNC Eddy heads, and a victor/Dom, at 3550 # race weight the car goes 10.00 at 134 mph. I think the 535 will have plenty of power.

Well I'm hoping so AG! I'm not too concerned about the peak numbers, and sure it will be enough power for a nice street 'experience' !

I thrashed on it over the weekend, took yesterday off too, I'm REALLY close, only have a couple things left to be where I was before.

I had to gasket match the intake to the new engine, that took most of the time, but I feel pretty confident over this next weekend I will be at a point where I can fire it up.

Here's a shot of where I'm at now, about the only things left are some clean up tasks, bolt the converter back up, and adjust the shift cable.

Once that's done, will take it up to get the exhaust welded up, front end alignment, charge the AC, and get a state inspection. Will have some detail work to do, and fix a couple other small items, but I can drive it while I do that!
