What length adjustable pushrod to measure for my build?

[TexasRoadRunner68]

Any ballpark of what size I should get for a low deck with trick flow 270s and t&d 1.6 rockers?

I have to get one for degree if the cam anyways. Any feedback from someone who has built something similar would help.

When I bought there were 2 available, one for a RB, the other for a B engine. Regardless of heads it should be the same. I bought both. If you need ones for cup end rockers there are also 2 available.

This is the shorter of the 2, and I would assume the B engine.

Make sure you get the correct ball end for the lifters you're using. Just saying.

Could cut a piece of coat hanger for a rough mock up

I think that should work.
My 440 engine with hydraulic roller cam has pushrods that are about 8.5" long, and the low deck block is 3/4" shorter deck (0.745") than the 440.

i just use an old push rod with a section cut out of it and thread both ends for 1/4"-28 all-thread. add a couple of nuts to locate everything.

The 270's are relatively high. I'm not entirely sure you're going to find something out of the box. I cut mine to length to get exactly what I wanted. I'm with @Jerry Hall, get the TF pushrod tool, put the heads on, measure carefully, and then cut. Also, when you cut your own you get a LOT more options.
