Tech Question
Jerry Anderson, Panama City Beach, FL, 1970 Plymouth Cuda
Hello Mr. Ehrenberg,
I am building a 70 Hemi Cuda Clone. I am planning to install a Hemi with a 4 speed. I have read about the Stage V conversion heads for 440 blocks. I have 3 440's. My question, are these good heads? And which way would you go, with these on a 440 or a new crate hemi? thanks
Jerry, there's nothing wrong with the Stage V Engineering heads, they flow well and make plenty of power. But then you'll have a one-off engine with parts that are basically non-interchangeable with anything else. And a relatively weak block, to boot.
The crate Hemi, when it reappears sometime next spring, will be built by Barton (the last batch was done by Cummins) and will be a super-quality product, with the clear advantage of 100% parts interchangeability with any other Hemi.
If you're in a rush, you'll be using a used block, be it 426H or 440W, since the reason that there's no crate engines is that the MP blocks are on IGBO (intergalalctic back-order), although Barton has a small stash of 'em. Alternately, finding a good, factory cross-bolted Hemi block, and having someone like Barton build it, seems like today's best plan.
Rick
