Any intake, any carb(s), mechanical injection OK. No EFI. Points distributor or magneto only.
Transman, what is the rod journal dia on that 3.48 crank?

I'm not sure if you know Ron Flood...............North Branch , Mn. , but soon to be up Pine City way. I believe he has a set of the B - RB to Hemi conversion heads , and Lord knows what else he has squirreled away , but he might be a good brain to pick for a project like this. Cedar Machine.( 651 ) 674 - 8365 He is semi retired , but I think he would not be opposed to any project that was cool or interesting , and this sounds like both.

Transman, what is the rod journal dia on that 3.48 crank? Standard B/RB - 2.375” with standard mains - 2.750”. I also have a longer set of NASCAR rods at 7.06”.

That's good info to consider, Boff. What is the highest rod/stroke ratio that will still pull hard enuff on the intake to make big power?

Never mind, I'm sure it will be successful.

What about destroking/sleeving a 383/400 with Max-Wedge heads? Custom/welded intakes allowed?

Can you move the lifter bores around? The Wescott and Barton stuff all has the lifter bores moved, to straighten out the pushrod geometry. They have done for years.

We tried that before the de-stroked Hemi. 361 block. 348 cubic inches, port matched maxwedge heads, single 4 bbl. Ran it way past 8500. 4 speed. I think you would be hard pressed to get close to Hemi power even with state of the art raised port maxies. Valve train would be easier to sort out on a wedge.

THE BIGGEST PROBLEM WITH THAT KIND OF RPM IS STABLIZING THE VALVE TRAIN. RAY BARTON AND JESEL ARE NOW GETTING A HOLD OF IT AT 10500. ANYTING MORE THAN THAT I DONT KNOW.
