What is needed to put a 153 (on center) engine into a TR?

Pushrods being at a slight angle while not idea are not as much of a problem as you would think. I've worked on a lot of pretty serious BBC and SBC with severe pushrod angles that would scare you that don't have issues.
On another note you CAN run a stock intake on an on center . I did it when i first started running TSE at Bowling Green . You had to run a stock intake at the time. The bolt holes have to be enlarged and you can't get the ports lined up perfectly. They will be off about 3/32" unless you do a little welding on the outside of the intake ports and do some creative porting. It won't be pefect but it will work. My car ran 9.40's with the stock intake . After TA/ Champinion came out with there race intake and they changed rules to allow it i swithed to it. Car went a best of 9.27 with the TA intake. This was a max effort class legal car at 3600 pounds.

You can slightly slot the holes on a stock intake and get it to bolt on to a on center block. Eric Rankin used to do it all the time.

I've had a stock intake set up on mine and see how this would work. Ideally the China rail area would need a little tig work to change the angles to match the block. Extra RVT would probably be fine as well

What I did with mine, too.
