So, first "W" I'm building and just wanted to tickle the brains of more knowledge than i have on these 348s....
I have a late model truck block, X on front left of block, single notch (block is at Machine shop to get bored to clean it up and new freeze plugs etc so i dont have the Casting # handy). I have 4 good 333 head castings that i can rebuild. I'm planning to put the engine in my 68 C-10 truck I've had for decades. I plan to make the truck a daily driver when i retire in 6 years. Plan to run holly sniper EFI as well.
My issue is: Keep it with my stock now turned 10/10 348 crank new scat/eagle rods and run a 9.5/1 or 10.5/1 piston (forged), run a decent cam, with a range of idle to 5000 or so (daily driver, but still want it to be fun to drive, and love a noticeable idle)....
or
Drop in a 4" crank, new rods, nothing over a 10.5/1 piston (want to run it off pump gas) same rough cam spec?
I'd run the matching alum edelbrock intake for both....
Is the 4" crank worth it? I know unless i do some porting work the 333 heads dont do much, but what power do you thing is expected with the stock crank and 333 heads compared to the 4" crank and 333 heads? Drivability? durability? I dont plan to race it other than use the gas on occasion off a light or to pass on the highway... Thoughts? advice?
