Cheap BBC

probably a tall deck block

BARRIE, ONTARIO

yeah I was gonna say the same 366 or 427 ???? . I forget but there,s something about the distance from deck to timing cover ??? to tell the difference ..77.

58Chev · ETOBICOKE, ONT

I have no clue on the difference.
Just thought a whole truck for 1,200 as opposed to another add for a just pulled 1970 BBC on a pallet for over $5Gs. Looked to be in the same condition.

I''m gonna guess a 366 as most C60 had those with Holly/Governed Carb which I can see in Picture!!! Not a engine you'd want in a car, lots of low end torque & don't think many parts are interchangeable with other BBC. Make a good "toy hauler" ramp truck?????

tall deck bbc in a car works just fine

ditch the old intake & carb , swap on a set of square port bbc heads and an eddelbrock tunnel ram and a pair of 660's - see what happens

a buddy and I put one in his 69 camero just like that

motor was in his 68 chevelle with a 4bbl intake - that worked just fine too

it was a tall deck 454

427 tall deck is a good start to build a big inch stoker motor, a 366 not so much

I stuck a tall deck forge steel crank out of a 366 into my 4 bolt main 454 block.

you don't just bolt on a short deck intake to a tall deck - you need spacers which these days are hard to come by

DJD · SCARBOROUGH, ONT

I've never seen spacers for one - just intakes like my buddie's that were cast for tall deck bb chevy

The crate 502 and 572 are tall deck engins as well. I would imagine there are some interchangable parts there, but still I agree Ron, the 366 is not a great engine to start from.

A 366 is a boat anchor - only good for the oil pan, forged crank, and truck rods. Everything else on the motor is basically junk.

The 427 tall deck is a good start to a big stroker - you can get a 4.5" stroke crank in them for an inexpensive 520+ ci.

You start needing a lot of grinding on the oil pan rails and need a stroker profiled oil pan when you get into 4.5" and above strokes. But the rotating assemblies all cost about the same so if you are going to stroke it, might as well go big. The cylinder walls on the truck blocks tend to be very thick because of the cylinders unsupported length and because it was designed for severe use. I have seen many of these blocks with cylinder walls approaching .350" thick when sonic checked. You could bore these blocks a full .125" over without a problem, and still have room for another cleanup bore if needed. With the 4.5" arm and .125 overbore, you get a cheap 540.

Hardblocking the bottom of the cylinders reduces the unsupported length of the cylinders for greater strength, while having little effect on cooling. It also ensures that you will not have water leaks if your clearance grinding gets into the water jacket.

Just have to be careful of cam clearance so stroker profiled rods with 12 point nuts are required and maybe a reduced base circle cam when you get into big strokers.
