HEMI heads are NOT nitrous friendly, nor does that type motor have a good design for big cubes. They can flow big air, but NOT without boost to push it through there. In a big nitrous motor you need bore, not stroke. You also need as close to a flat top as you can get for a proper flame front, neither of which the HEMI has. The relatively small bore, huge knot to make compression and weight of said piston are all detriments. There is a REASON all the fastest nitrous cars on the planet run a wedge. And while the Sonny's "Chemi" rules the roost in big inch pro-stock, with it's flattened piston and chamber design, that design does NOT favor in the nitrous world........and it HAS been tried, several times.

Thanks for the reply.

The injected fuel guys in Top Alky seem to do OK without the boost but I get what you're saying. S/F....Ken M
