Just finished a customer of ours 5.9 build using our Iron heads, 9.4:1, small OE EFI friendly cam (around 210@ .050), our house 750carb / TTI step headers and Harland Sharp 1.7 rockers...
It made 418HP and 437TQ and idles at 800rpm with just a hint of a note at the tail pipe...

Nice power! What throttle body is it going to run when installed? Is that a Hughes/Edelbrock intake or did you modify an intake?
That is the Hughes intake, untouched. I'm not sure which TB he's using, I can find out and let you know.

That would be amazing if it would run with the OEM Computer/injection.

I have bigger cam, cubes and compression and it runs great with the factory injection. About all I did was add 460 ferd fuel infectors.

Cool,thanks,Nice work on your part to get the numbers.Do you think the EFI will produce similar power levels?

Yes I think it will be down a few, but not many.
