Prosport: beautiful car. Thanks for the insight!

It does everything better, with 1/3 less fuel. The torque isnt as broad, but good gawd. Keep in mind I have a 420" Gen III though. Ray Meyers is a great example of a comparison, he had a way more stout BB than I did.

Thanks, I wonder how a blown 392 gen III would compare to a big block?

There would be no comparison, a Whipple at 10lbs is usually a 700RWHP combo. Pump gas mind you. I was going to build a 400/499 deal and after I did all the math, for the same money I gained EFI in the process. And no valve adjustments, phantom oil leaks or questionable block strength. Like I said earlier, to have the same power AND reliability, you need a solid roller in a BB. Once that bridge is crossed, things start adding up to get daily driver reliability.

Bigblock stroker is what I would do and did do on my 63 but its not real big. The 400 is the best to use if you are ok with the intake selection on the lowblock. I went with the 440 because I may go to a crossram one day and I knew I only planned to make around 600 flywheel hp. If I wanted to make closer to 700 hp I would either go with the 400 block or a aftermarket 440 block. The new Hemi's will make great power but I just like seeing an eng that looks kinda like what came in the car.

And Prosport that eng looks awesome. Bottom line is you only have to please yourself. Also have you done a price comparison of the new Gen III Hemi vs the 400 or 440 setup ? Ron
