So since I've recently decided to keep going with my C10 rather than get rid of it. I started looking for a big block to put on a stand and build little by little. My goal would be a street able 650-750 ish...
I found a guy selling a bare 427 tall deck with 4 bolt mains for $250, I'm planning on haggling to $200. So I'd be building the thing from the bottom up. Even though I'd love for it to come with the crank. It doesn't. So I'd be getting it to a machine shop to be restored and then buying all the parts as I like them, with advice ofc. This engine would ultimately be swapped in once the truck AND the engine are both finished and only missing each other.
For all the grumpy old timers here that will rip me to shreds if I post a question that has been beat more than a dead horse without using the search feature.... I DID USE It! Lol Here's what I've learned so far:
-Tall deck block is called a tall deck because the deck is .400" taller than the standard block
-originally used in truck applications
-the extra deck helped to fit pistons that had a fourth ring on it
-low rpm/high torque/low hp in stock form
- short deck intake manifold will not fit without spacers.
-the factory cranks were great on them.
However, I still have questions.
I just bought a complete Stage 3 upgrade kit for the factory AC on my truck from Classic Auto Air in Tampa Fl that would convert it to r134a along with a modern style compressor, the kit includes everything needed to overhaul the whole system, seals, o rings, evaporator core, hoses, brackets, accumulator etc. This kit will fit my 305 and the guy on the phone told me that when I do eventually convert to Big block all I'd have to do is call them back and get new brackets for the compressor and a compressor with a serpentine belt pulley since I told him I was going with a serpentine belt drive in the big block instead of V-Belt, he said everything else would be the same.
- How much does the tall deck block affect my plans with this?
- I imagine that the brackets for the compressor would be different due to the increased valley spacing, does anyone know if there is a company making brackets for modern compressors on tall decks?
To anyone that has actually used a tall deck in a C10 square.
-how is the header clearance?
-does it make the engine bay excessively tight?
-will I run into issues with fitting an upgraded power brake setup?
-does parts availability make it a lot more expensive to build a tall deck?
Anything else you guys know about these blocks and heir fitment that I should take into account before I decide on the tall deck?
Any info will be greatly appreciated.
