427 SBC & 4L80e build

[72K5CSTDarkOlive]

[QUOTE=TexasT;8336265]What made it need to a 1.125" bore on the mc? Rear Disk upgrade? I love the hydroboost set up. I think they work great on my stuff, though I just used stock stuff on mine.

I was told that the bigger bore would give it more pedal travel but less pedal effort and I also think too because I'm doing disc/disc. It was a recommendation from the place I got the Hydro unit from.


That bare block is SEXXY!

I'd like to know the particulars of the 4l80e build also. Did the tc just require a new 32 spline input? I know that is what I did to the np246 I put together for our Burb when the pump rub took out the original.

Great build! Keep On Keeping on. My neighbors would be having a coronary if I had our truck on stands for more then an afternoon.

Thank you! Luckily, I was able to get the trans/tcase installed that same day. I went to Harbor Freight and picked up a transmission jack to do the install. I put it back in the box very neatly like no one ever used it and returned it that same day.

I'm waiting for the guy who built my trans/tcase to get back into town. He's been out of the country for a few weeks. I'll make sure to get all the details that went into the build and update this thread when I do.

Looks like they dynoed with a carb? Timing stated to be 40*. Is this locked there or are you running a dist with vac advance and mech advance or one? I'm no guru but the bsfc looks low and the engine might could use some tuning to get more out of it. Either way it DEFINATELY makes PAH! Will they be making any pulls with your fuelie setup?

We had to use a carb because we didn't have an EFI pump that would have been sufficient enough to use at the dyno. The distributor is mechanical advanced only and is not locked out. It comes into total timing around 2800 rpm and when the dyno is testing (starts at 3500 rpm) it's already fully advanced.

My engine builder thinks we could get more out of too because it was running a little more on the rich side and if he had some more time he could have leaned it out a bit. The Cam has 4 degrees advanced built into it to help with the bottom end so if we didn't advance the cam we definitely could have picked up more on the top end but I'd rarely ever take advantage of using that power at 6500+ rpms.

A chassis dyno might be in the foreseeable future!
