Default considering a 454.. tall block work?

I have acquired a sandblasted and por15 coated rolling chassis off a 68. mine is a 71 (both coupes)- since the frame is going to be sitting in my garage along the vette for future use (my frame is really bad).. I was thinking that I might buy a 454 and put it in the chassis sitting there as that would be the time to do it if I go that route. hoping to drive the car this summer way it is if I can get all the stuff working and do frame swap next summer. My question is this: I know where I can get a rebuilt 454 (7 years ago) with 3000 miles on it since rebuild. But it is a TBI engine I think in a 1 ton truck so is that worth the hassle? I'd have to change to carb and not sure what all is involved. it also may be a 'tall' block? ( I understand there is tall and otherwise reg) - I can get the engine for about $500

no its got to be a reg deck BBC,
but

look at the water pump mounting holes,are they just below the deck surface 1/8-1/4''? or are they 3/4'' or more below?

and I don't remember any 454 tall deck engs,just 366 and 427,,and then only in 4500-5500-6500 trucks

1-tons got passenger deck blocks.
TBI could be anywhere from '87 to '95. Probably flat tops. You can still swap intake and drop in a cam that will take advantage of what cylinder compression is there to be a decent engine.
Post the casting number along with head castings and we'll see what you have.
And help you spend your money

If it's TBI it's probably 454 standard deck. Ensure it has a fuel pump pad on passenger side to feed a carb. If so, it'll need only an intake manifold & carb. 366 & 427 TD not worth fooling with regardless of $... not when Too many 454 available.

I picked up a really nice 454, 4 bolt, Mark IV block out of a 1990 1 ton pickup truck.
The block was $500.00 plus $150.00 for the machine shop to mag, test, check the bores and bearing journals.

Pickup trucks are not trucks. Pickups, suburbans and campers built on G30 Van's got pass car low deck blocks. Truck blocks were put in big trucks. Spend their lives at full throttle so they need another compression ring. People think tall decks are better for building big cube long stroke engines, but cam is in the same place. Oil pan rails too. Only real advantage is ability to use longer rods.
