Thanks, Wayne!

I read the article about direct injection in a recent Hot Rod Magazine, but your link provided more details about how the system operates.

there seem to be 3 pages... or many pictures..

here is direct to page 2

Fancy stuff that, and it proves the internal combustion engine isn't nearly dead yet.

So how so you adapt this to a 350 Chevy?

i was actually thinking about it... i really need to look at the the angle of the nozzles into the head... there might be room between the coolant passage and the pair of intake runners... where the exhaust crossover was... and again between the rear pair of intake runners and the rear coolant passage..

CoPPooPPoC

C is a coolant passage
o is where the injector will pass through the deck
P is the intake port..

it might be easier to do something like world products did.. and make a conventional bolt pattern small block chevy head with the best L92 head ports...

i would bet that gm engineering has a pair of prototype direct injection heads for the LS series of motors..

i wonder if there is any wear problems with the far cylinder wall.. as it might get washed down a bit.. but i guess that would depend on at what point the cycle the spray is started...

i seem to recall that some of the motors this year might be direct injection

those might be interesting to examine...
