Suggestions/help for my 440 build/swap

Mine is in the car as of two days ago, with lots of help from this forum. I am no expert by any stretch, but maybe something I did can help you in some way

Mine is a 71 K member so biscuit mounts, using the Schumacher inspired trans dapt SBM to BBM mount kit. You will have alot easier of time with the 73+ K member you have for sure

I went with Schumacher Tri Y's, and bought the 'advance exhaust' kit for intermediate pipes. I think Schumacher might be sold out again, but I can tell you there is a ton of room with the Schumachers for pretty much everything. I have not put plugs in yet but i do not see any issues like the ones I read about with TTI's and others.

Starter can go in and out with no issue.

Loads of room with a manual steering box. Clears my u joint deal I hobbled together.

For radiator I went with ALL30306 It will piss off alot of purists but I would rather have a crossflow rad any day over the normal Mopar rad. Yes I agree the Mopar rads look, well they look rad. Also, it fits so very well, no height issues at all as it is quite short in comparison. Most 26" 'budget' rads for Mopar are a bit too tall for A body without doing something with the cradle.

The trans fits like the stock one did, no issues there, so no issues with Yoke/shaft. You will need a 727 yoke if you currently have a 904. I bought a used A body driveshaft as mine did not have one and it has a 904 yoke so no bueno.

It is a budget build that of course didnt really follow a budget in weird spots. Aluminum heads/intake/water pump housing to make it light. I would almost bet its not much heavier than an all ironed up 340/360

You won't need to notch the K member for oil pump clearance the same way I had to given you are running spool mounts, but there might still be issues there? Someone on here will know
