They are not direct injected. The injectors can be in the head or in the intake or both. I've seen 16 injector setups. The injectors in the head are above the valves. If they were direct injected, the injector would be in the cylinder and be timed of the crank. This is just a constant flow system that has a cam driven fuel pump and bypasses to tune.

how much do one of these things cost?

[btman2]

@crv26 ALOT!

[ProfessorIgor]

I would think this is a 360.. there aren't any in the head direct injectors on this engine. Most, if not all guys use them on 410's... GREAT sound none the less !

[haggis240]

@ProfessorIgor 410 are not injected into the heads

[ProfessorIgor]

@haggis240 you better take a better look at the engines at an Outlaw event... they ALL run DI systems.. and they are all 410's

[haggis240]

@ProfessorIgor sorry i was thinking of our 372 setup

[arizonaresident1]

@haggis240 What's a 372?

[haggis240]

@arizonaresident1 a 372 motor we used to run them all the time here untill all the tracks went to 410 but their are still a few about

[arizonaresident1]

@haggis240 What I mean is how do you make one? You're not talking about a 377? a 350 block and 400 crank?

[arizonaresident1]

@haggis240 I meant a 400 block and 350 crank isa 377, I've never heard of a 372.

[haggis240]

@arizonaresident1 good question i will look into it when we kick off our season again wich will hopefully be soon i am sick of watching others have all the fun

[motocrossrider19]

ahhh that sounds like sex

[lotsapower101]

So curiously if that is a 310 what rules are they runnin the car by with aluminum heads? 360 and 410 are allowed aluminum heads not the 305 class sprints

[wildroot57]

Really? I do not know.  I knew about 360 and 410s.

[xKFCchickenx]

no offense but thats a 310 hahaha

[lotsapower101]
