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.

Thank you sir!
What style lifter & pushrod diameter did you use, and how much fuss was it to clearance the pushrod holes in the cylinder heads?

From what I understand, anything larger than a 5/16” pushrod could be a real challenge especially with a hydraulic lifter with a centered plunger.

I used the TA SI heads with this setup which the pushrod is off set for the head already. Ran 5/16 push rod with short travel johnson lifters billet roller custom ground cam. Very lil head clearance at all to push rod holes. Cam is like 225 230 so like 560 ish and i run a 1.55 roller rocker again TA's because are there heads.

On 16 psi on a hankook kinergy tire car goes 11.00 flat 130mph and that spinning pretty good. On good tire it goes 10.4 same boost off foot brake. Ths is 100 percent street car, spare tire ,a/c cruise full interior. No cage
