unfortunatly my fathats 72 monte carlo was totaled, leaving a perfect 350 small block chevy behind, i was wondering what i would need to swap that into my 86 t/a both are carbbed i ma in need of a shopping list if any motor is comming out friday and maybe in the firebird as soon as saturday at the moment i have a carbed 305 with a t-5 tranny that i think will bolt up no problem, will be shopping for a t-5 soon

any input will be appreciated, andi have searched probly not using te right trems though

 

youll need tools and to remember where all the bolts go at

 

so its a direct bolt on no sensors t ore locate nothing to adapt?

 

The '86 has a one-piece rear main seal, which means the crank flywheel flange is different than the '72 two-piece rear main seal flange. You will need a flywheel for the '83-'85 f-body T5 application. Your '86 starter may or may not fit on the '72 block, but that's what you need. Check the starter mount bolt holes in the '72 block - if they're the same as the '86 block, it'll work.

The '86 has the oil dipstick on the passenger side. The '72 has the dipstick on the driver's side. The '86 manifold gets in the way of the dipstick tube, and the '72 manifolds won't fit in the chassis. Headers solves that problem (along with solving the restriction problem of the '86 manifolds).

The '86 305 has a knock sensor that is tuned for the 305. You need a knock sensor tuned for the 350. The knock sensor module also needs to be replaced for the same reason. This is assuming you plan to use the '86 carb and distributor on the '72 350 (highly recommended).

Everything else should transfer from the 305 to the 350.
