Master cylinder for a T56?

[90'rado]

What year 6 lug front rotor will you go to? I know the 92 year had a wider rotor than earlier years. I assume that a 6 lug rotor from a 96 to 98 will work but, I am not sure of year they changed to 6 lug.
Is your 14 bolt a full float or semi with locker?
I looked for the McLeod shifter relocation and can't find anything on it for T56. Where did you guys see that? I also would like to keep stock shifter location and short shifts.

Any 6 lug front rotor from an 88-98 truck should work. As far as I know, most 2WD 1/2 tons from 88-98 were 5 lug. I believe that most, if not all 4WD truck in this year range had 6 lugs. Also, I'm pretty sure that all the 3/4 tons had at least 6 lugs, sometimes 8. So, either a rotor from a 4WD or a rotor from the light duty 3/4 ton, which would be 6 lugs.

The 14 bolt I have is a semi float. The full floaters are all 8 lugs and are overkill for a street setup. The semi float version has a 9-1/2" ring gear so it's got some serious beef to it. The axle is going to receive a TrueTrac

I think it should be about right if you look at the picture of the stock location in 90'rado's. I spoke with Red on Friday and the part number for 4.1" forward and not side offset is 81-420-294-08 for the F-body T56. He's coming out with a newer model that will have a bolt on offset arm instead of welded as the current one is. He said with the bolt on you can just send him back the offset arm for something different.

What is cost of shifter? I looked at S&P,but could not get to pricing page? I like the ideal of bolt on offset arm so if not satisfied with location you can send it back for better fit. It looks like 90' rado must be 6'13" by how far his seat is back.

From S&P it was $279 and $251 direct from Red were the quotes I had.

I'm not quite that tall. The bench just about had to be that far back to clear the shifter for 2,4 and 6.

I think I will look into ordering one of the shifters with the 4.1 forward but I would like to have it offset to driver by 2/3 inches.

Where did you get the motor mounts? stock location or set back 1". Did you you use the Walbro 255 fuel pump? Whose wiring harness and what computer(411?) did you use? Stock Exhaust/Headers?
I found O Reilly has a 6 lug 11" front rotor p/n 81-125205 that is the about the same as the 5 lug 11"rotor on my truck now.

I think the reason my driveshaft had to be changed was both the v6 and the 5 speed. The 5 speed is shorter than a 700R4 4L0E.
If I hadn't shortened it, I would have had to move the rear end back a few inches.
I figured it easier to shorten the shaft

Old Nash, I'm still running a SBC in my truck for now. I think S&P sells the motor mount plates which bolt to the LS block, and then your regular SBC "clamshell" mounts bolt to those. Walbro 255 should work great for a 6.0L. 411 seems to be a pretty common PCM to use for the LQ4 swap. I'd try to get the harness from the donor truck and then you can either merge that harness with the one in your truck, or send it off and have it done, I think S&P does that too. It shouldn't be too hard though, you'd just basically rip out the old ECM and most wires associated with it, leaving wiring for chassis electrical stuff, ya know wipers, headlights etc.

Thanks for posting up that p/n on the 6 lug rotor, I might have to buy new ones. I'm going to try to use the 6 lug rotors off a parts truck I have first and see what gives there.

I'll probably use these headers once I do the LQ4 swap
