I have just recently aquired a tall deck 427. I would like to know who(or where) produces perfomance parts for these engines? What can I get ,aftermarket for 'em, and what can I interchange?
I have pretty much always dealt with SB chevy's. I know the basics remain the same, but must admit to being slightly intimidated by the BB's.
Thanks, in advance for any help.......Konrad
All the parts are pretty much the same for the 427 tall block and short block, except the intake manifold and distributor. Since the tall block is a truck engine, it is going to have some real clunky pistons (4 rings instead of 3), a real sluggish cam and a distributor with governor. A good set of pistons, mild cam and aftermarket distributor will make the engine run pretty well. Used to be that you would have to use spacers to run a decent intake manifold but there are now tall block manifolds available from Dart and others. As I recall the truck engine used a huge water pump too, pass car pump can be installed. Have fun.

I bought a 427 tall block for my mud truck a 74 chevy i had been looking for a flex plate but didnt know if it was an internally or externally balanced.
There are a few manufacturers that make intakes with a regular distributor height location so any standard GM or aftermarket distributor can be used. The only other consideration that I can think of is being the decks are .400" taller, regular headers usually don't fit well.
I do believe the truck engines have a steel crank in them also, which is good. And as stated above, they are an internal balanced assembly.
I have a friend that has a tall deck in a 68 Camaro that spins it to 7500 regularly and sometimes to 8000RPM. Stock GM crank and aftermarket rods.
Edelbrock, Brodox, and Dart make the intakes with the recess for use with a standard GM dizzy.
Just built a 505 with one.
